Re: MySQL Spawns Many Processes and Uses 100% CPU! PART #1
Okay, here is the problem: everyone once in a while, say once or twice a day, my web server running RH 7.2, PHP 4.0.6 and MySQL, will seem to freeze (from a web users point of view). Upon SSH'ing into the server, and running top I see the system load averages in the 90s (!!!) and all I see for processes on the list is mysqld. The CPU usage is at 100%, and the top mysqld process ususally is taking 14% or so, then 12% then a lot of 10%, and on down until it goes off the list. This is what I used to have. We invoked the scenario described in http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html and since then things went back to normal without any other tuning. Oh, one more thing: I changed pconnect to connect in php. So it looks as like we had load problems at times due to poor hd performance which gave trouble to mysql. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

So all you have to do to make your phpMyAdmin unvulnerable is to
change 2 types of lines in 7 instances in 2 files, see:
http://www.securereality.com.au/patches/phpMyAdmin-SecureReality.diff
In particular, these are:
-if(file_exists($goto))
+if(file_exists(./$goto))
-include($goto);
+include(preg_replace('/\.\.*/', '.', $goto));
With respect to general security, this is of interest also, in

Re: synchronisation (replication)

If so, can someone point me in the right direction Well, I'll give it another try. The answer is Yes and No. Yes: you can replicate databases. You set up one database as a master and any number of other as slaves. These slaves may reside on the same machine or on any number of other machines. It is a one-way communication. The master is used to change data, the slaves to read data only. Very clean concept, seems to work well, although I didn't try it personally yet. No: as far as I understand your question, you want to synchronize data between your local machine and the webserver in a two way process. This is something I do regularly for some reason, i.e. users insert/delete/update the web database, I insert/delete/update some data locally for testing and later addition to the web. I don't see any way to automate such a two way communication, and it is certainly not possible with the replication mechanisms at hand. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Replication
My ISP provides me with a MySQL database. I have installed MyODBC and MySQL on my Windows2000 machine. Can you tell me if its possible to replicate the database to my own computer, make changes and these be replicated back to the database hosted by my ISP ? You will have to do it manually, I guess. This is how I do it: If it is a one time operation, I use mysqldump, i.e. in Win it is \path_to_mysqlbin\mysqldump \path_to_datadir\db_name \your_path\update.sql on the local machine, I upload the sql file via ftp, then feed it into mysql like this /path_to_mysqlbin/mysql -hlocalhost -uuser_name -p /path_to_datadir/db_name /your_path/update.sql If I have a large db and little changes, this would be overkill. What I do is get a dump from the table I changed with phpMyAdmin (just a click), copy the row(s) added to an instance of phpMyAdmin pointing to my web site to a new file (a snap with my editor), paste it to the sql textarea and click the go button. If it is more than a few records, this is not feasible either, so I upload that file via ftp and feed it like above into mysql. If somebody knows an easier way, I'd be glad to learn. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Patrice Garbe schrieb am Donnerstag, 9. August 2001, 14:20:04: Then It is not a memory problem for ini_set() didn't work. It always crashes at the same point. Mysql doc says : ERROR 2008: MySQL client ran out of memory note that the error refers to the MySQL client mysql. The reason for this error is simply that the client does not have enough memory to store the whole result. But as I said the query works with phpMyAdmin and is performed several times in the script with free_results() after each performing. So look at the difference between phpMyAdmin and your script. I assume that you put your query into phpMyAdmin and that's it. In your script, you will obtain the same result when you do the same, as phpMyAdmin does nothing else than call the usual php functions. Therefore, I assume that you will do some other sort of things in your script, like a huge while loop which eats up memory. It isn't hard to construct such a thing. You didn't provide your code, did you? Patrice Le jeu, 09 aoû 2001, vous avez écrit : If it is a memory problem, try for example ini_set(memory_limit, 16M); in your script.

You have timestamp fields in your table. When the user connects, you insert a row. The first timestamp field is set to the entry time automatically, you just record the user.

reading error
I experience entries in hostname.err like 010806 11:05:48 Aborted connection 1780 to db: 'pferdezeitung' user: 'pferdezeitung' host: `localhost' (Got an error reading communication packets) The frequency of serious problems has dropped since we changed RAM modules. The ISP tells me that he performed fsck after that which proves to him that there is _no_ hardware problem on the machine. So - what else can be the cause of the error? If I have few of those (reading or writing), the machine still runs, but if I have lots of them in the same second (say 40), mysqld and httpd change to status D in top and load average rises, response times get very bad. They have a cron job checking the bad condition every minute, which will kill and restart http, now every 5 hours or so, so we can live with it somehow. Before they changed RAM (and upgraded from 384 MB to 768), restart frequency was about 30 minutes. Anything I can do or tell my ISP? We run on Intel single CPU 700 MHz, Linux Suse with Kernel 2.2.19, Server Apache/1.3.19 PHP/4.0.4pl1 I told him that Sinisa recommended Kernel 2.4 and they tell me, that all of their machines run with 2.2.19 with no problems. They tell me they have one client with more than 1 million hits per day and a huge MySQL database, who never had problems. I asked about check free space on both datadir and TMPDIR and they say no problem. We run 3.23.33 and they don't dare to change versions because of possible problems. I don't have any experience. I suppose I could unpack and just change executables, but I am reluctant to try. We moved to that ISP 4 weeks ago. Before that, we never had any errors of that kind (reading or writing) AFAICS. We didn't have any problems the first 10 days (or we didn't notice them), then all of a sudden things went crazy. Quite naturally, I looked for programming errors first, but I can't find any and it doesn't look like there are any. We did have those errors right from the start, though, roughly 6.000 per day, more than 60.000 until we had massive problems and I found out about it in hostname.err.

CREATE TABLE NPGE_RETTEN_TMP ( NP_NR NUMERIC(7,0) NOT NULL, GE_NR NUMERIC(18,0) NOT NULL, ORTSANGABE VARCHAR(100), TELEFON_NR VARCHAR(50), TELEFAX_NR VARCHAR(50), TEL_VORWAHL VARCHAR(20), BUCHTITEL VARCHAR(100), ANREDETITEL VARCHAR(20), BT_SCHLUESSEL VARCHAR(5), BEMERKUNG VARCHAR(100), LOESCHKZ VARCHAR(1), U_VERSION VARCHAR(1) ); Normally, I've got this error when using KEY(x, y, x) where the column length of x, y and z overrides 500 chars.

No Database Selected /weird behaviour
Errno: 1046 Error: No Database Selected I get this on only one of my sites, on the first query during a connection only, and actually it is an impossible error. All sites are driven by db_mysql.inc from PHPLIB. Therefore, everything is totally automatic, no chance to omit the database name during connect. In fact, when the query returns that error, I jump in between and look for all the parameters, and indeed, they are present, including the database -- nothing else could be expected. If it occurs, it is a simple query SELECT * FROM lgs which will return the languages supported at the time, three right now. Simple table, simple query, three rows, so I guess the problem is not located here. I could hard code that stuff as well, but why? It worked fine for a year. So this is rather interesting indeed. Also, it does no harm as I default to a standard language if the query doesn't work. But I get an email notice, so I know. The rest runs fine, I didn't have problems although I reuse the connection and do a lot of other queries shortly thereafter. I notice this for at least 6 months now. It happens mostly in intervals, say once a day on three days a week. During the last week, the behavior changed slightly. I received thousands of notices during the period of about one or two hours, then things went back to normal. Before, I mostly received tens or at most hundreds of notices. top shows a really funny picture if it happens: typically no httpd, but 20 or more mysqld processes. I had a look at the hostname.log which looked rather normal, issuing queries that ought to be expected during normal page generation. hostname.err shows Number of processes running now: 34 mysqld process hanging, pid 2830 - killed Currently, there is only this client on the machine. Previously, I had another site on the same machine which produced much more load. Back then, I experienced similar problems with processes hanging. Is this a clue to something?

Re: Query Acting Weird
Adam Douglas schrieb am Donnerstag, 2. August 2001, 19:14:15: I have a group of 3 queries that's used to find our representative for Unitary, Applied and Wholesale based on a Zip Code. This all is executed through PHP to MySQL. The three queries work fine and get the results I want. The problem is the 3 queries seem to work one minute but not the next. You could enter say 3 or 4 zip codes and have it return results with no problem, but on the 5 try it will crap out. This seems to be random, one minute it wouldn't work on the first try and then the next it will. When the 3 queries crap out it renders MySQL useless, you can send or do any thing to MySQL when the 3 queries crap out. It puts my CPU usage to 99.0% and stays roughly there forever. I've left the query running for more then 8 hours and still nothing seems to be returned. Can anyone direct me in the right direction on how to resolve this problem? I didn't have a look at your code as I don't think it is probable that you will have a problem here. These days, I am hunting problems similarly weird. I'm looking into faulty hardware now. Yesterday, we changed 2 of the 3 128 MB RAM modules, which has reduced problem frequency from 30 minutes to 10 hours. We see from hostname.err that the problem occurs exactly when the log records 010802 22:35:30 Aborted connection 231 to db: 'pferdezeitung' user: 'pferdezeitung' host: `localhost' (Got an error writing communication packets) So we will replace the 3rd module or all three to see what will happen then. It might be the hard disk, though, or the controller, or something else. Also, it may be a good idea to look at the hostname.log to see what mysql does when running wild. I did this to test queries that seemingly produced errors, but when reproduced, they did not, so this was proof that neither the query nor the data had problems. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: How to add an excel file directly to MySQL database using PHP?
Yeong CN schrieb am Freitag, 3. August 2001, 06:43:11: How can I add an excel file with *.xls extension directly into MySQL database..is it possible to do or I need to convert it into *.csv format or *.txt format first? You can put anything into MySQL provided you choose the right column type. In this case, you should use one of the text or blob types. Make sure you escape the special characters. If you program in php, you wrap the input with the function addslashes which does the job for you, and you strip the escapes back on retrieval with stripslashes. If you don't want to operate on these files, it is probably not a good idea to put them into the database. In this case, the general considerations regarding pictures apply. Here is what Rasmus says about storing pictures in databases: When dealing with images, it is of course possible to insert the image data into the database as binary blobs. However, the value in doing that is questionable. Until databases provide you with cool pattern recognition tools that will let you search a blob for a picture of a rose, having the image data itself in the database isn't of much use. Every operating system comes with a finely tuned blob database. It is called your file system. So, just put the full-path filename into the database and leave the images sitting somewhere on your disk. You will save yourself much aggrevation in the long run. As the data format of Microsoft files is not very good documented, I wonder what operations you may want to perform on those. Of course, they do have some ASCII inside you may search for. You seem to be willing to sacrifice all Excel specific data, which will happen if you convert to csv or txt. This looks like you are only interested in the plain ASCII and structure and don't want to conserve anything that adds on that. In this case it will be a good idea to convert xls to any of these formats, because you will save a lot of space. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Writing 100+ fields with Perl DBI
I don't see the problem. If you have a table with 120 columns and
need to populate it, do you not want to do it with one insert
statement? What else?
I am not very familiar with perl, but in php it would be easy for
me to construct the insert statement:
You can read the columns names into one array; the values are in
the array $HTTP_POST_VARS; so you loop over the arrays and build
parts of your insert statement -- you only have to make sure you
get the correspondence correct.
If you name the columns accordingly, you don't even have to ask
mysql about them. So you say:
$q = 'INSERT INTO table (';
for ($i = 1; $i 120; $i++) {
$q .= 'Q' . $i . ', ';
}
$q = substr($q, 0, -2);
//take off the last ', '
$q .= ') VALUES (';
while(list(, $val) = each($HTTP_POST_VARS)) {
$q .= '$val', ;
}
$q = substr($q, 0, -2);
//take off the last ', '
$q .= ')';
//you are done, hoopefully, with something like
//INSERT INTO table (..., ...) VALUES ('...', ...)

In my application I'm writing up to 120 fields of data in one swoop
(the results of a sort of survey). I'm using Perl DBI with MySQL.
Each survey has several fields of data like 'name' (stored as
parameters in the CGI object $asmt) and then up to 100 actual survey
questions (Q1, Q2, etc). Until now I've just written one line of
data to a text file, like:
# Write basic data
print FILE asmt - param('name') . \t;
print FILE asmt - param('city') . \t;
$v = 1;
#write response to each question (Q1, Q2 etc)
while ($v = $questions) {
$x = Q . $v;
print FILE $asmt - param($x). \t;
$v++;
}
And this works fine for the text file - but from what I've seen I
probably can't carry over the iteration through the (up to) 100
actual survey questions. I named the MySQL fields 'q1', 'q2',
anticipating some way to do a loop, but I can't see it.
Does anyone have any suggestions of how best to do this? The thought
of one huge INSERT statement makes my eyes glaze over - I'm hoping
there is a more elegant alternative.
Thanks,
Nelson

Re: Parsing text file into mysql database.
I'll give you an example, step-by-step.
I didn't do that kind of thing myself yet, so I had a look at the
manual. First, I discovered that mysql can take all kinds of
separators (I read that before, but forgot about it), so you
don't have to convert at all, as you can signal different
separators and delimiters to mysql.
To get a text file in the first place, I issued the following
command:
SELECT * INTO OUTFILE result.txt
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY ''
LINES TERMINATED BY \\n
FROM autoren;
Here you see already that you can specify exactly how you want
the records to be written. The result looked like this:
1,Werner Stürenburg,[EMAIL PROTECTED]
2,Priv. Doz. Dr. med. Th. Rommel,
3,Regina Steinkrauss,[EMAIL PROTECTED]

11,Elizabeth Wener,
12,Marianne Schwöbel,
13,Merten-Melching,
14,Dr. Otto Marré,
15,Taschen Verlag,[EMAIL PROTECTED]
Now let's reverse the process. I used phpMyAdmin to copy the
table autoren to autoren2, structure only (enter name + click).
Now I issued the command
LOAD DATA INFILE 'result3.txt' INTO TABLE autoren2
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY ''
LINES TERMINATED BY \\n;
again from phpMyAdmin. This populated the new table with those
values. Both tables are identical.
I did all this on my local Win system. If you do it on your
server, there are differences in syntax regarding the location of
your text file, residing either on your local machine or the
server. The latter is faster, as the data doesn't have to travel
across the phone line (it had to earlier to get there in the first
place), but you need the FILE priviledge in the user table to be
able to do that.
So if your text file is very large, I'd suggest you compress it,
transfer it to the server, decompress it and load from there -
make sure you have the file priviledge or else give it to
yourself in this case.
The advantage of this approach is that it is straightforward and
as fast as can be.

I don't have the original post any more, but you will have some
kind of file where the records are lines and the fileds in the
record are separated by some kind of character, say tab or blank
or anything else, but you will know what.
So let's say the filename is $filename and the separator is $sep.
Then you read the content of the file into an array with
$content = file($filename);
Now the elements of the array are the records. You will have to
convert the separator into , to get csv style. There are several
styles to do that, for example
while(list($key, $val) = each($comment)) {
$content[$key] = str_replace($sep, ',', $val);
}
Now $content should be written to a file to feed to mysql. Well,
this is a common task, and there isn't a handy php function as
far as I know, so I wrote it myself (see below). With that
function, I don't have to think about all that mumbo jumbo and
get it right nevertheless:
stringToFile(implode(\n, $content), $filename_csv);
The implode function transforms the array to a string which can
be written to the file, glueing the rows together with \n (new
line) in this case.
function stringToFile($str, $filename, $mode=a){
$fp = fopen($filename,$mode);
$res = fwrite($fp, $str);
fclose($fp);
return $res;
}
Of course, I have written the reverse function, too:
function fileToString($filename, $sep=' ') {
return @implode($sep, @file($filename));
}
The @ insures that no error messages are shown. So this function
will return nothing if the file does not exist.

Re: Parsing text file into mysql database.
Well, you can't do that with LOAD DATA INFILE.
You will have to write some piece of code for that. Like so...
$content = file($filename);
while(list($key, $val) = each($content)) {//sorry,
//I had a typo in here in my prev. post
$content[$key] = do_some_error_checking($val);
}
with some do_some_error_checking function
or
while(list($key, $val) = each($content)) {
if (do_some_error_checking($val)){
$correct_content[] = $val;
}
}
and then work with $correct_content. Once you are at it, why
don't you
while(list($key, $val) = each($content)) {
if (do_some_error_checking($val)){
insert_my_data_into_table($val);
}
}
with the appropriate insert_my_data_into_table function, where
your do_some_error_checking will return true or false only.
You would get faster and better answers if you would provide as
much info on your problem as possible. Don't hesitate to provide
sample code and/or data - it is easy to skip text but impossible
to imagine missing information.

Do it like any other insert, but care for special characters. In php, you would wrap data with addSlashes() and remove them on retrieval with stripSlashes(). But... you better not insert images into a table. Yes, you can do it, but it is generally considered a bad idea. Read about it at http://www.bitbybit.dk/mysqlfaq/ - if the images have to be provided by users, use the upload functions of your system. php for example has upload support built in. Next you have to care for the appropriate write rights for those files. These can be handled safely without compromising system security. Store all data associated with the pictures in a table except the picture itself, which should be taken care of by the file sytem. [EMAIL PROTECTED] schrieb am Montag, 30.

Write yourself a function like roundCurr() and then insert
roundCurr($row[xan]*$rcurr) instead. To get a hint, how to do
that, look at php.net and do a little research. You want to
behave your reound function in a certain way, and it can be done
very elegantly, as I remember, but I don't remember how and I
don't want to do the work for you..

Re: timestamp problem
Omit the value for timestamp. mysql will do all by itself.
Kory Wheatley schrieb am Freitag, 27. Juli 2001, 01:17:22:
I'm using PHP to add records into a mysql database. The records write
successfully to the database
except for the timestamp field which I have defined as
Field Type Null Key
Default Extra
TheDatetimestamp(14) YES NULL
Everytime I write a record or edit a record it puts 000 in
the TheDate, which of course is not the correct date.
Here is the insert command below that I'm using, does anyone have a
solution.
$query3 = INSERT INTO Quser VALUES('', '$fullname', '$add_novell',
'$tot_novell', '$add_cwis', '$tot_cwis', '$add_mail', '$tot_mail',
'TIMESTAMP');
mysql_query($query3);
is the TIMESTAMP option where I get the current date from.

top reports Status D
Server Version: Apache/1.3.19 (Unix) PHP/4.0.4pl1 MySQL 3.23.33 To find out about a peculiar phenomenon I am hunting for 10 days already, I added a stopwatch and record for each URL the elapsed time from entry of page construction to end. Right from the start, I get significant data: auto Timestamp URL secs 178 20010727193459 Preis/30-35 1.06 179 20010727193459 Preis/35-40 0.41 180 20010727193500 Preis/18-20 81.55 181 20010727193505 Preis/40-45 0.81 182 20010727193505 Anzeigen/Woche/9 2.68 183 20010727193526 1461 0.47 184 20010727193531 Preis/20-25 91.86 185 20010727193538 4485 0.17 186 20010727193549 Berichte/120 0.56 Entries 180 and 184 are extreme. All Preis-URLs fetch classifieds within that price range (horses 30.000-35.000 DM, for example). As can be seen from the timestamp alone, this is no human scanning the pages, rather a spider. The program is always the same, the table also, the only difference are the conditioning numbers for the query. Therefore, it is not likely to be a program or query fault, as this should produce equally bad figures on all URLs with that pattern. The table in question for the above data is ok, as might be suspected, because it is the same table with all queries, slow or fast. I just made a manual test with URL Preis/18-20: it took 2.98 seconds - so this is proof that it is not the data range that produces the differences. I show at most 10 records, and clearly there will be more in this range than in range 40-45 (in fact, we have no offers in this range right now). Time is consumed not in fetching the data but in producing the html for presenting the data. Did anybody ever see something like this? Should I upgrade to 3.23.40? Is it plausible that this is a problem with MySQL in the first place? Any places to look at in addition? Any ideas of how to track this thing down? What else can I say? When watching top, things go nicely for a while. If there is high load, it is significant that mostly httpd processes are shown, very seldom a mysql process. All of a sudden, the picture changes. Some mysql processes show with status column showing D instead of R, meaning uninterruptible sleep versus running. Looking at processlist, I may or may not see mysql processes. If I do, there are all kinds of status reports like sorting, opening, copying to tmp table etc. Without that state, I have little chance to see any processes at all (except root looking for processlist :-)), which seems to show that mysql is extremely fast. With these few mysql processes in status D, very fast some httpd processes show status D as well, and in addition, if there were many processes running and showing before, we have only a few shown with status D and few if any running. So if I let top run in the background without really watching, I will notice this change by the number of rows shown. Response time will decline very fast, load average will rise instead, and we have seen values of up to 200, at which situation the machine is essentially non responding to anything. The only remedy we know to date is killing and restarting Apache, which we do with a cron job every minute evaluating load average, but that's just a workaround for the moment. We will refine this watching for status D. I thought about bad queries or faulty code, but the data above does not back this idea. Also, we thought that the machine could not handle the load, but it happens with few hits as well and does not seem to accelerate significantly with heavy load. Actually, I don't know if the data shown above relates to Status D or not, but it is highly peculiar in any case and maybe significant. These are the first data that really show something weird. I have processlist and Apache status, but neither showed anything valuable. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: auto_increment, is this a bug?? Where to report it?
We had this discussion here a couple of days ago. There are versions of MySQL who behave this way, but it is mostly not considered the correct way. So you may as well get used to the idea that an autoincremented field is doomed to increment no matter what. That got me thinking...say you have a list of 500 people, and you delete the person with id 500 (The Person with the very last ID). Now, your ID's go up to 499. Now say someone else is added. Would they have an id of 500 or 501? For me it would be 500, which would create a security problem, but I very well could be doing something wrong. Is this a typical behavior? -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Many students - each with own DB - would like to restrict size of each DB
I think this is a problem similar to that of ISPs. I don't know about this technique personally, as I am not fit on Linux/Unix, but restricting disc space on those systems is standard, so you will know how to do that. Databases for MySQL are just subdirectories, as you may already know, so you may very easily restrict disc usage on those subdirs for each student. Also, you may use symbolic links and place those subdirs into the dir structure you provide for the students anyway. Surinder S. Dio schrieb am Montag, 23. Juli 2001, 17:09:54: Hi, I work in a university and need to give students access to a MySQL database from their php enabled web server. The apache/php stuff is all working but I was wondering on some advise as to how best to deal with a large number of students. Ideally waht I'd like to do is to setup MySQL so that each student has their own unique database, accessible from their own userid, this would mean a large (1000) number of relatively small databases (I'm hoping to restrict each student to approx 20Mb for Db usage) and they could setup their own tables etc via something like phpMyAdmin. They can have full access rights to their own individual db - but not see any other students's. The machine I've set aside for this purpose is a Sun Ultra 5 - 256Mb ram - plenty of swap and fast local disk. ALso I want to restrict the size of the database for each studnet - as this is only for learning php/mysql purposes and if theirs a more serious project then I can provide other facilities. Is this going to to be achievable - how are other Uni's or ISP who provide MySQL dealing with this tpye of issue. If I can't restrict the size of each database - should I be pursuing some other db option?

If the latter does make sense economically is another question. The usual prescription for things not implemented is to look for a work around.

Re: concept of users connecting from different host
i don't understand what does connecting from different host mean? Where do you have this problem? 1. does it mean connecting from a different pc to the pc hosting the mysql server through telnet? Why would you like to do that? looks like a masochistic approach to me, under normal circumstances. 2. connecting from the same pc hosting the mysql server and specifying the host when connecting? Which would be localhost then, right? 3. running mysql client on a local computer and connecting to the pc hosting the mysql server. how do you connect in thisway then? Well, i do it through the browser as I use mysql on my server. in this approach, the connection is done through a cgi program running on the server, in my case php. in other words, I use php functions to connect to mysql, which means that the program connects to localhost. If I would like to connect, say, from your program on one machine to a database on another machine, then you will have to address that machine directly, for example with the IP number of that machine. You will have to insert a new user in the mysql database. Example: I manage my server databases through phpMyAdmin. This is a server based program, so it connects like all other server stuff through localhost. No problem. Recently, I downloaded mysqlfront (http://www.mysqlfront.de/). I liked that program very much, but as it runs as a standalone program on my client machine, it can connect to the database on that machine as localhost, but not to the web server. In order to do that, I would have to set up a new user and such. Another example. In addition to my own project, I have several customer projects. When I wanted to integrate data from a customer into my own project, I couldn't connect to the database of the customer directly because the ISP wouldn't allow it. When we moved to our own dedicated server, I moved the site of this customer to this machine, too. As I was master of this machine now, I could have realized my original plan to tap into the live data of this customer. In this case, both databases would reside on localhost. But it turned out that we had some problems. Now we moved our project to a separate dedicated server. As I am master of both machines, I will have to introduce the machine address of our project into the user table of the machine with the customer's data to realize my original plan. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: REPLACE single value
Sorry, I didn't use replace yet, I always work with update which
is what I want. Are you sure you want to use replace? See the
differences in the manual. The syntax for update is
UPDATE table_name
SET col1 = '$val1',
col2 = '$val2',
col3 = '$val3'
WHERE primKey = '$id'
or something -- you get the idea.
REPLACE contacts (access) VALUE ('P') WHERE id=x

Re: mysql.org
Absolutely great! You are so keen and brave - I wouldn't dare to and some others obviously neither! We need people who calm things down to make negotiations and an agreement possible, that's absolutely true, but we also need people to emphasize the frontiers to make a correct agreement possible in the first place. If it is not possible to distinguish between right or wrong, how will you hope to reach a basis that will last? It is not a question of politics, but of ethics and morals. I know that these are not counted upon in business, but ultimately this is what drives the world. And nobody will ever change the basic principles. You may have short term success violating those principles, but they will not last. Yesterday, I read an interesting German article about Bill Gates. A nice parallel was drawn to Napoleon and the like. All of these had huge success on the short run, but failed very soon. When I started in my computer business, Nixdorf was overwhelmingly successful. Five years later, they didn't exist anymore. They, like all big players at the time, held their customers hostage. Nobody liked that, so as soon as they had a chance they took their choice. The same will happen with Microsoft and any other endeavor which tries to force people into something which they don't really want. On the other hand, the open source movement is driven by huge energies which cannot be bought by money, no matter how much you want to throw at it. As they are negotiating right now, as far as I remember, this beautiful analysis may come a little late. On the other hand, they plan to take breaks and communicate, so I hope both parties will get to know your arguments. You are, of course, welcome to your opinion, and to the expression of said opinion. You are also liable to be judged on the basis of that expression, and frankly, your expression leaves me wondering about your wisdom and your analytical capabilities, not to mention your social skills. What - you work for NuShpere. My analysis of this affair is correct. It comes down to trust I TRUST MONTY. I do not trust Brit, and man who has abused the GPL, abused the MYSQL trademark, and broke the trust between the two partners. What do I base that trust on 6 years of contant communication and dependency of the MYSQL staff and my PERSONAL relationship with Monty and his Fella's as he called them. Furthmore, the assumption that under any condition NuSphere BROUGHT the right to open up shop directly under the MYSQL name and conduct independent sales, promotion and business, is damn off the wall, far fetched, and ridicules to asume, that you'd have to be a complete utter moron to beleive this report, and in addition, the report should be playing tomorrow afternoon on the Opra show, and be reported right next to the alien abduction story in the National Enquirer. Furthermore, their behavior secondary to this, and the proposition that they opened the mysql.org site as a Community site flies right in the face of the proposition forwarded by NuShpere that they opened the site with full rights to do so under previous agreements because they purchased control over the MYSQL trademark because they did in secret, then protested they had they right ot, after saying it was a communitee site, and then finally, they release they're Gemini code on it, only after 100's of people complained that they were violating the GPL. This is NOT the actions of an honest person...period... No We need NuSphere to admit their wrongs, make a blanket apology, and everyone can call a no harm no foul, and forget it happened.

Re: auto_increment, is this a bug?? Where to report it?
The problem is...if I delete the third entry (Edicao = 3), the next entry inserted should be 3, right?! Well it is not! It is 4. Well, this may be debated. I suffered a lot from the behaviour you want to have. I considered it bad design ... An autoincrement field should not serve for counting or numbering but for making sure that you have a unique key - no more and no less - without having to think about it. If you count on this - that every record will have its own number no matter what happens - then the number of a deleted record _must_ be discarded. Of course, you can live with both implementations if you know what happens and what you're doing. Lastly, the trouble I had was nothing else than bad design. Relying on the unique key, populated other tables with this foreign key. When the row was deleted, I didn't care about deleting the dependent rows in the other tables and files connected with them (pictures). As a result, there was a good chance that somebody had the wrong picture in their classifieds: big embarrassment! Took me some time to find out about this scenario. Of course, the bad design was that I didn't care about deleting all dependencies including the files. But otherwise, I wouldn't have run into problems at all and only wasted disk space which isn't that much of a value these days. If you care to look at the manual, you will find explanations about this change in design. I don't remember the details now, but I know that I have seen them. Use the search box and you will find it fast. This explains why the behavior changes with the versions. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Is last_insert_id reliable?
Currently, I have been counting the rows in PHP in order to get the value of the last hit_id in the database like this: You have mysql_insert_id() in php to get the last autoincrement value. This is _not_necessarily_ the same as the number of rows. It's staggering the difference in speed. But if I sit there and hit refresh on the browser, I get wildly different values for $pixels. It jumps around the actual number by +-10 or 12. The first method is precisely the same every time (unless a hit is recorded in the interim). Am I doing something wrong here? Well, I imagine that the last inserted id (not number of rows) will be given after you have actually inserted a row. I never tried to ask twice. Did you ever find that a variable in php shows a totally obscure value? If so, you may find that the value was not defined at all and point to some random memory block which contains some value from another process which you see. Maybe this is the case with mysql, too. So you better be sure to look for what you refer to. I made a search on LAST_INSERT_ID but it returned 0 results in mysql.com. Funny. Can I not count on MySQL to know how many rows it has recorded in a table? Any idea why that select statement would select a different row each time? This is a different question. You should ask SELECT count(*) as num FROM hits and then look at the value of num to get an answer to that question. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: blob question
Generally, it is not advised to add pictures to tables. See http://www.bitbybit.dk/mysqlfaq/faq.html#storing_images We had this question here some days ago, so it may ge a good idea to discuss at length possible problems why people won't like this approach of storing pics as files. WARNING: this is _not_ MySQL specific. You may want to stop reading here. 2nd WARNING: I will also show what can be done with all that information to arrive at some kind of content management wizardry. After all, people do use MySQL to do something with it, and many seem to manage pictures. So here it goes. If you let people upload images with php (which is built in and really easy) you will receive the images in, say some sort of tmp dir. You will have to move them in your code to a separate storage dir, as php will automatically delete the tmp files (see manual). Now php is part of httpd and that runs as nobody, so it cannot write to that storage dir unless you open that dir to nobody. This will be ok as you use this dir only for the purpose of storing those third party images. You may protect it in addition with .htaccess or move it out of the normal dir tree if you are a little paranoid. Now you can store the images as files with no problem and only note the filename and type or such (for example comments of the user to the picture) in the database. When you upload, you move the file, so this is a good point to record the file in your table. Once you are at it, you can retrieve the dimensions of that image with php function getImageSize and store them in your table together with the type as well. So now you know everything about this file you need for inclusion in your html code. Hence you write yourself a function, say getImgCode, which produces the html tags from this info, so you can insert the whole stuff into your code without any further thought like ... ?php getImgCode(firstNameOfMyPicture) ? ...

Re: UPDATEing values in SET columns
I would take another approach.
table 1 has only user_id
table 2 has flag values and key user_id
So you just insert rows or delete them in table 2. That's it.
Did I understand your problem?

Hi
I have been searching through the manual and the list archives for the last
few days regarding a problem I have with the SET column type.
I'm creating an app that uses a SET column as 'flags'. Different parts
within the application will check to see if certain 'flags' are enabled. As
I understand, the SET column uses bit representation internally.
My problem is updating the column with flags already set. Below is an
example:
The table is as follows:
CREATE TABLE users ...
user_id INT ...
user_flags SET('another','test','pass_renew','none') NOT NULL DEFAULT
'none'
...
When I update a record, I can only set the whole string not just the
individual flag.
i.e. This works fine...
UPDATE users SET user_flags = 'test, none' WHERE user_id = 1
How can I add (or remove) values within the SET column without affecting the
existing contents?
I've tried a number of ways with no success!!
For example
UPDATE users SET user_flags = CONCAT(user_flags,'pass_renew') WHERE user_id
= 1
Any help or pointers would be greatly appreciated.
Thanks
Nick Brandon

Re: blob question
What I need to know is: 1. what would the create table statment look like in Mysql. DROP TABLE IF EXISTS pictures; CREATE TABLE pictures ( id mediumint(4) NOT NULL auto_increment, comment text NOT NULL, width smallint(6) DEFAULT '0' NOT NULL, height smallint(6) DEFAULT '0' NOT NULL, format varchar(4) NOT NULL, PRIMARY KEY (id), KEY pid (pid) ); You may add other colums as needed or create other tables with foreign keys to this to connect the picture data to other data, e.g. texts, classifieds, whatever. 2. Should I use a longblob based on my 100k .gif size? You should provide for enough space in the field to hold your data. The field definitions tell you what is provided. If you deliver greater values than storage space, MySQL will truncate your data. You will want to acoid this. 3. Is one column with the gifs enough. Or should I add a autoincremented primary key? That is always a good idea, unless you use a foreign key which in turn will most probably be an autoincremented key itself. 4. Is it better to have a seperate table for this or, is it better to update my existing table, and add a blob column. Does it matter in terms of speed of queries? I would create a separate table. No, rather I would not store pictures in a table, as said. Werner Stuerenburg wrote: Generally, it is not advised to add pictures to tables. See http://www.bitbybit.dk/mysqlfaq/faq.html#storing_images We had this question here some days ago, so it may ge a good idea to discuss at length possible problems why people won't like this approach of storing pics as files. WARNING: this is _not_ MySQL specific. You may want to stop reading here. 2nd WARNING: I will also show what can be done with all that information to arrive at some kind of content management wizardry. After all, people do use MySQL to do something with it, and many seem to manage pictures. So here it goes. If you let people upload images with php (which is built in and really easy) you will receive the images in, say some sort of tmp dir. You will have to move them in your code to a separate storage dir, as php will automatically delete the tmp files (see manual). Now php is part of httpd and that runs as nobody, so it cannot write to that storage dir unless you open that dir to nobody. This will be ok as you use this dir only for the purpose of storing those third party images. You may protect it in addition with .htaccess or move it out of the normal dir tree if you are a little paranoid. Now you can store the images as files with no problem and only note the filename and type or such (for example comments of the user to the picture) in the database. When you upload, you move the file, so this is a good point to record the file in your table. Once you are at it, you can retrieve the dimensions of that image with php function getImageSize and store them in your table together with the type as well. So now you know everything about this file you need for inclusion in your html code. Hence you write yourself a function, say getImgCode, which produces the html tags from this info, so you can insert the whole stuff into your code without any further thought like ... ?php getImgCode(firstNameOfMyPicture) ? ... You may even go a step further if you are in at content production. Let's assume the user uploads any text and pictures. The user is instructed to embed their pics with special syntax like ... stuff stuff stuff *MyImageFirstName* stuff stuff stuff ... You later insert the image with $content = preg_replace(/\*(\w+)\*/e, getImgCode($1), $content); This example is taken from http://php.net/manual/en/ref.pcre.php (I developed a content management system along these lines on my own, but this is just stunning - an incentive to learn the art of regular expressions).

Re: Questions about extremely large database support
Is mySQL up to such a task? I have been using mySQL for four years now, but have never used it in a project of this magnitude. We'll be handling financial data in the database, so integrity is important. I think so. You find impressive statements on the mysql site about speed size reliability incl. testimonials. Also, you may want to consider the new innobase table type - see statements at their site as well. Where can I find information about very large databases with mySQL? See above. Also you will find statements in the list archives lists.mysql.com, but you may have a harder time searching the appropriate posts. Is there a really efficient way to implement a function like indexseek() in FoxPro? This function will simply check an index to tell you if a record with that key exists. Sort of like select count(id) from Foo where id=1 except that it doesn't actually fetch the field value and it just checks the index file, not the data file. As far as I know that's exactly what MySQL does. -- Herzlich Werner Stuerenburg _ ISIS Verlag, Teut 3, D-32683 Barntrup-Alverdissen Tel 0(049) 5224-997 407 · Fax 0(049) 5224-997 409 http://pferdezeitung.de - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
