segfault in mysql_real_escape_string
Hi folks,
I've the main developer of nss-mysql. I've found out a very strange
problem.
On a Debian potato, mysql 3.23.38 and glibc 2.1.3
This bit of code segfault on the last line. The string useris correct
(printed correctly in log).
/* we escape the user string */
secure_user = malloc(strlen(user) * 2 + 1);
if ( secure_user == NULL ) {
_nss_mysql_log(LOG_ERR,initgroups: not enough memory to escape the
user string);
*errnop = EAGAIN;
return NSS_STATUS_TRYAGAIN;
}
mysql_real_escape_string(mysql_auth,secure_user,user,strlen(user));
This part is taken from the initgroups function and segfaults everytime
when called from Apache. I've noticed that upgrading libc to 2.2.4
fixes the problem. I guess this is a problem in the client lib.
Any hints will be welcome.

RE: Help needed getting table headings into an outfile
Sorry, I should have given you more information about the problem.
We have a Java program, with a J2EE backend which is connected to a MySQL
database.
The database is running on a windows 2000 machine, and we want to output the
contents of the tables in text format(CSV). I can get the formatting ok,
but it just needs the table headings.
Ideally we want to use one or more queries to do this, rather than using
mysqldump.

your output script.

my $sth = $dbh-prepare( $statement ) ;
$sth-execute();
my $fields = $sth-{NUM_OF_FIELDS};

Hi,
I keep sending this to the list, but im not sure if anyone else is getting
it.
I hope you can help me with this.
I am using the INTO OUTFILE 'filename' function, to create .CSV output
files
from my queries.
Whenever I do this, the table headings are removed from the output. Is
there a way to get the table headings displayed in the output file?
Thanks in advance

Login with password fails with jdbc

I'm trying to connect to a mySQL database on the
localhost through a jdbc (mm.mysql.jdbc-1.2b I
downloaded it from mySQL home page) driver, but I
cannot establish the connection for users that need a

following:
private String url = jdbc:mysql://localhost/test;
public static void main(String[] args) {
ProvaJDBC thisclass = new ProvaJDBC();
try {
Class.forName(org.gjt.mm.mysql.Driver).newInstance();
Driver dr =
DriverManager.getDriver(thisclass.url);
System.out.println(Connessione:
+dr.acceptsURL(thisclass.url)+
+dr.getMinorVersion());
Connection con =
DriverManager.getConnection(thisclass.url, user,
password
..
}
}
catch(SQLException e) {
System.out.println(SQLException: +
e.getMessage());
System.out.println(SQLState: +
e.getSQLState());
System.out.println(VendorError: +
e.getErrorCode());
e.printStackTrace();
}
This code works perfectly for users that don't need to
specify a password (that is, I specify a null or void string password),
while it gets an error when a
password is needed. The error is:

Cincinnatti was beating us 3-1, and I led off the bottom of the eighth with a walk. The next hitter banged a hard single to right field. Feeling the wind at my back, I rounded second and kept going, sliding safely into third base. With runners at first and third, and home-run hitter Ralph Kiner at bat, our manager put in the fast Brandy Davis to run for the player at first. Even with Kiner hitting and a change to win the game with a home run, Brandy took off for second and made it. Now we had runners at second and third. I'm standing at third, knowing I'm not going anywhere, and see Brandy start to take a lead. All of a sudden, here he comes. He makes a great slide into third, and I scream, Brandy, where are you going? He looks up, and shouts, Back to second if I can make it.
Column definition: The EXTRA column
I am trying to use the EXTRA column that exist in mySQL ( DEFAULT EXTRA FIELD KEY NULL PRIVILEGES TYPE), but I do not understand how to put a value into it, I can get the value with SHOW COLUMNS, but I can not set it, andd it seem to be totally ignored in the manual.

Notice about seconds overroll - S7K bug
(This is third attempt to post. always failed in some reason) I would like to make your attention on bug which was introduced tonight and can affect some people who are using (var)char field to store timestamp data. It is not worst security bug. It affects only people who already had bug in their code. Just now this bug become visible/exploitable. This is not MySQL bug. This is how people use their database. Also similar situation can be found in other software. I would like to inform people in public list as maybe some people have to search similar problems. The problem: Computers store time and date usually as integer value representing amount of seconds from 1 January 1970. Tonight it overrolled from 9 to 10. Possible bug and exploit relies on fact that some people have used character type of field to store this seconds information (we have already such case) example: mysql create table session (expire varchar(100) not null); Query OK, 0 rows affected (0.31 sec) mysql insert into session values (7), (8), (9), (10), (11); Query OK, 5 rows affected (0.00 sec) Records: 5 Duplicates: 0 Warnings: 0 mysql mysql select * from session; ++ | expire | ++ | 7 | | 8 | | 9 | | 10 | | 11 | ++ 5 rows in set (0.00 sec) mysql Let's assume that this table contains values we use somewhere to authenticate users. After user logs in, we write down session expiry time and later we check it like this: mysql select count(*) from session where expire = '132535'; +--+ | count(*) | +--+ |3 | +--+ 1 row in set (0.00 sec) mysql WOW, what happened? Shouldn't be 13253 bigger than any value in table? It worked yesterday! In MySQL we suggested people to use quotation marks around integer values. This can avoid many web-based attacks targeted to modify SQL commands (more information on http://www.mysql.com/doc/G/e/General_security.html). This is the reason why people put quotation marks around integer expressions and this is correct. Also automatic type casting will fix the source problem is column data is integer or some time/date vale. But when both column is character type and expression, they get compared as strings. And as we know, strings get sorted in order: 1,11,2,22 but integers: 1.2.11.22 So, this is why 13253 10 It is possible that some web applicatons have endless expiry times now and not only in MySQL contexts. -- For technical support contracts, goto https://order.mysql.com/ __ ___ ___ __ / |/ /_ __/ __/ __ \/ /Mr. Tonu Samuel [EMAIL PROTECTED] / /|_/ / // /\ \/ /_/ / /__ MySQL AB, Security Administrator /_/ /_/\_, /___/\___\_\___/ Hong Kong, China ___/ www.mysql.com - 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?

show columns
Hi Folks - simple Q from a newbie, I'd like to return only the column names using something like show columns. I'm using PHP to display db tables in html, with the headers of the html table url'ed to sort the result by field. It's easy when you hard-code the column names into the page, but I'm going by the table name only, and need to work with an array of the column names to print out the html table header. Help appreciated; thx in advance.

Stored procedures (2)
I've got a tour on the web, searching for info and ideas, regarding the subject to implement some sort of stored procedure in mysql (remember Lets approach stored procedure thread ?) This was what I discovered - The Perl stored procedures (myperl project) in not a good idea at all, but, even if called poor man's stored procedure, I think that this project don't add, actually, stored procedure in the precise meamning of term. It add only a binding with Perl via UDF. It's a nice (and quite simple) hack. Dana Power, I've not take a look to _your_ hack, but I think this is the same approach. - I had searched everywhere the ANSI SQL3 directive... not luck. I only found a 1994 document where this directives were proposed It is quite incomprensile, though (like all standard doc I have read :) - I'm evalueting the IBM DB2 approach. Since the ol' COBOL days (rattles...) I remember the EXEC SQL ... END-EXEC commands embedded inside the COBOL as the host language. At compile time there was a cross-compile step the produced some code to get recompiled and finally linked and binded. This is also the (old?) informix approach, where SQL EXECs were embedded inside the C source, and then a cross-compile (or precompiler) make the dirty work, creating another C source that could finally be compiled and linked. But I don't know to have some (low skilled) SQL coders to be well skilled in some other language to write down a stored procedure. So here came my idea: use a SIMPLE language to write the logic of the stored procedure (no complex structures, definition and use of local variables, some test statement, error trapping, and of source free SQL coding), than use a precompiler to convert that source into the source of an UDF. At last, we had stored procedure written in a simple language, but compiled and used as UDFs. MySQL itself could then be used to store the packaging approach (as Oracle does), or other information regarding validation of the sp, last modification time, user... etc Just some thoughts Claudio Cicali mysql, database, tables - 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?

Select where A is not a member of B
Hi - I've got an annoying problem here, I've checked books, web, archives, etc, but can't find anything suitable so far.

Re: InnoDB tables : difficulties with COUNT(*), DELETE etc ...
Alex, slowness of count(*) is a well-known problem. I will fix it some time this fall. Not very easy, because of multiversioning and recovery. The other problem you have is that a delete operation ends up in a deadlock (I think it should not be called a 'crash'). I will write in October a selective deadlock resolution algorithm to InnoDB where a big transaction is not chosen as the victim in a deadlock situation. Unfortunately EXPLAIN does not work on a DELETE, and you cannot ask how MySQL does the delete. You should download the version 3.23.42 and do mysqlcreate table innodb_lock_monitor (a int) type = innodb; so that we would see what locks and lock waits happen during the delete. That could give us a clue how to fix the delete inefficiency.

compiling MySQLGUI
I am trying to compile MySQLGUI for solaris 8. I can't use the precompiled version as I do not have the same version shared library for libstdc++. Recompiling that at this point is not an option. The precompiled version is also several revisions old and not compiled for solaris 8 (this last argument does not stand on its own, but if I am going for the latest version, I might as well get it compiled for the same version).. The first issue I have it that MySQLGUI expects the fl_editor package to compile static libraries librcl and librcledit. However, the version distributed from the mysql.com site as well as newer versions on the maintainers site do not build these libraries. I had to get an older version (0.3) to get these files built. Using those static libraries I almost finished, but got a bunch of undefined symbol errors errors when trying to build the final binary. Thanks for your time.

indexes and desc
When doing a select that is ordered by a column that is indexed and has a limit, does mysql not use the index if the order by is descending? Here's an example: select parent,number,lastpost from posts where topic=1 and board='abc' and approved='yes' order by lastpost desc limit 9,12 My app is a message board and I'm using date descending as the order. One thought I had is to create a new column like desctime and set the value of each post to something like the time value for say 1/1/2025 minus the lastpost time - that should set it far enough out I wouldn't have to every worry about it. Another thought I guess would be to just store the value as a negative value. If it doesn't use the index in descending order, does anyone have any suggestions on my thoughts here or other ideas on how to work around this most efficiently? And are there future plans for indexing on desc order? - 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?

Index Question
Hello All, I've got a question that is likely an easy one, I just want confirmation from my peers. I have tables with a timestamp column and perform many selects and counts from these tables based on the date that the record was written. Can/should I index a timestamp column? I do my best to index columns that I specify in my WHERE clauses, however I haven't yet tried to index a timestamp column. Is it even possible? Is it advisable? Should I treat it as a char and limit it to just index on the portion of the data that distinguishes the date (I don't care about the time, just the date). Thanks!

Re: Index Question
From: [EMAIL PROTECTED] Can/should I index a timestamp column? Can: Yes. Should: Why not? Should I treat it as a char and limit it to just index on the portion of the data that distinguishes the date Hmm, I wouldn't. Offhand, I'd guess that MySQL handles time/date things as integers. I'm pretty sure that he also handles indexes as some sort of integer based serialization. Meaning that conversion to a string would be an extra step and thereby a loss. I'd say to try it a few different ways (if you have the time on this job) and find out what works best for you. --- Rodney Broom Programmer: Desert.Net Spam filter: sql - 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: MySQL Performance Problem
On Thu, Sep 06, 2001 at 05:26:53PM +0200, Henning Schroeder wrote: Find all the queries that interact with this table. EXPLAIN them. Time them. *all* of them? there are lots. Well, perhaps not initially but you may want to have EXPLAINed a majority of the queries that are issued against your database and probably all the ones that occur often. as said before, it is the main user table. a user account is updated every time somebody request a page. and i need to join to that table very often to find out, when the corresponding user logged in last and what his name is. bad design? bad idea? what do you think? It does seem to be a point of contention. i could split these queries below into multiple queries, first getting the userid and then firing off another query to get the name (without a join). but i thought letting the database handle this should be faster. I guess only benchmarking will show if it's faster. Generally though I've found that many very quick queries is preferable to MySQL than one large, slow query, even if the many queries take longer (all added together) than the one large query. This assumes a web-backend type of application. select * from cookies left join users on cookies.uid=users.uid left join sessions on users.uid=sessions.uid where cookies.cookie=e3bd03382561eb3619b66fbea2af217d; select * from cookies left join users on cookies.uid=users.uid left join extended on users.uid=extended.uid where cookies.cookie=5226220e3b62cef71a13524ec7a413ac; (above queries have to be performed at the beginning of every webpage to find the current user. i don´t really think they are slow; they just lock because of something else.) i just tried the above query ten times. result: 7x 0.00sec, 1x0.01, 1x0.02, 1x0.04. does that spell slow? Yes. I wouldn't let queries with times like these near a busy production server I was responsible for unless I was positive they wouldn't and couldn't happen more than a handful of times a day. :-) Post the output of EXPLAIN for these queries. Along with the create defns for these other tables. Explanations snipped doesn´t look too bad for me. except that timing information at the end :-(. but that´s because the database is almost completely locked up again (processlist full of queries with Locked status). the table definition is quite long, i´ll append it to the end of the mail. Yes, I see what you mean. :-) Since uid is the primary key for cookies, users, sessions and extended, I wonder if the database could be made happier overall by breaking the queries down... select uid from cookies where cookie = 5226220e3b62cef71a13524ec7a413ac select * from users where uid=$uid select * from sessions where uid=$uid select * from extended where uid=$uid These might ease the bottlenecks. An update to sessions (for example) will only delay for the (relatively quick) third query instead of on the first bigger query. Conversely, only the third query will delay updates to sessions. I assume (and I'm guessing here) that the bottlenecks are being caused by regular updates to sessions and, to a lesser extent, extended. Perhaps some normalisation of sessions might help? Chances are I'm missing an important subtlety in your use of left join though, so feel free to flame (offlist)... :-) well, yes. i noticed that :-(. thank you for your good explanation though. but i think it´s probably not very fruitful to look for queries in the processlist that have locked status, because they are probably not the slow ones that caused the block. am i correct? Pretty much. While queries that spend too much time in a locked state aren't directly to blame (I blame the queries that lock the tables :-), blame isn't really at issue: either make the tables not locked so much or make the queries less dependent on the locked tables. :-) i also tried logging the queries that appear often with copying to temp table status and now have a nice set of them, though i don´t quite understand *why* the are copying. below are two: (the rows count is *way* to high, probably because the timestamps are ancient by the time i ran explain select) select count(*) from adviews where click=f and uid=7618 and cid=11 and datestamp=999782664 mysql explain select count(*) from adviews where click=f and uid=7618 and cid=11 and datestamp=999782664 ; +-+--+-+--+-+---+--++ | table | type | possible_keys | key | key_len | ref | rows | Extra | +-+--+-+--+-+---+--++ | adviews | ref | uid,click,cid,datestamp | uid | 4 | const | 2365 | where used | +-+--+-+--+-+---+--++ 1 row in set (0.00 sec) index on all fields, optimized nightly.
Re: Let's approach stored procedures
Depending on the way you define things, MIN and MAX are essentially stored procedures that were programmed into MySQL. Why not let us make our own? This is already possible with Aggregate UDF 's.

Re: Stored procedures (2)
- The Perl stored procedures (myperl project) in not a good idea at all, but, even if called poor man's stored procedure, I think that this project don't add, actually, stored procedure in the precise meamning of term. It add only a binding with Perl via UDF. It's a nice (and quite simple) hack. Dana Power, I've not take a look to _your_ hack, but I think this is the same approach. Actually, its not. Its more along the lines of apache's CGI vs. mod_perl. And its not just perl, its an architecture for pluggable languages ( python, javascript, lisp, or your new pl/sql clone ), which is exactly what you're looking for, if im not mistaken. The problem you're going to have is that MySQL does not support callbacks into the engine - i.e. youre in the middle of an sql call when your function gets called ( whether its udf or something else doesnt matter ), halting everything - effectively pushing it onto 'the stack' - and making separate sql calls, is not supported. You'll find that the hardest part is overcoming the current 'atomic' architecture, which has been used to optimize pretty much every part of the engine ( atomic meaning that 1 sql call is 1 simple actions. ). Of course CREATE ... SELECT and INSERT ... SELECT are simple exceptions, but the same reason that Sub-Selects are non-trivial, is the same reason that stored procedures are non-trivial. dpk - 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?

'localhost' problem
hello all,
i am running mysql on a red hat linux v7.0 box. when i
am trying to connect to the mysql database to read a
table that is present in the mysql database i am
facing a strange problem. i am able to get into the
database(named 'newone') to read the table (named
'namelist') from the command line on the machine that
is running mysql in any of the following ways:
# mysql -u myname -p mypassword
# mysql -u myname -p mypassword -h localhost
# mysql -u myname -p mypassword -h mydomain.edu
All these 3 commands are successful, without returning
an error.
So i have created a php file named 'namelist.php' to
read this 'namelist' table, which reads like the
following:
html
head
titleName List/title
/head
body
?php
mysql_connect ('localhost','myname','mypassword') or
die ('bUnable to connect to the database/b');
mysql_select_db ('newone') or die ('bUnable to
connect to the database/b');
$result = mysql_query (select * from namelist);
printf (First Name: %sbr\n, mysql_result($result,
0, firstname));
printf (Last Name: %sbr\n, mysql_result($result,
0, lastname));
?
/body
/html
when i run this php script from the browser, it is
producing the following error:
Warning: MySQL Connection Failed: Can't connect to
local MySQL server through socket
'/var/lib/mysql/mysql.sock' (111) in
/var/www/html/namelist.php on line 7
Unable to connect to the database
But if change the 'localhost' to 'mydomain.edu' in
line 7 it shows the contents of the table on the
browser without any glitch. My question is eventhough
if it doesn't complain any thing from the command line
when i specify '-h localhost', why it returns the
above error when i run the script in a browser? i am
able to reach the index.html page from the browser by
typing any of the following, on the same machine:
127.0.01
localhost
mydomain.edu
138.xx.xx.xx --my ip address
Can any one please help me with this.

Still Searching for Accent solution - MySQL 3.23
Hello, I'm still having problems with MySQL 3.23 being accent sensitive during searches. However, I'm now tested to ensure I'm getting the correct accented search term to MySQL. Here's my test page, which includes a small database of names with 2 entries per name, one including an accented vowel. http://www.sedl.org/accents.html If you search for Jose (no accent on the e) you get Jose (no accent) If you search for José (with accent on the é) you get José (with accent) At first, I thought it might be a problem with MySQL not recieveing the accented value in the search term correctly, but that still doesn't answer why searching for Jose (no accent) doesn't act like a wildcard to pull up the record with the accented value as well as the unaccented value.

RE: ASP MySQL
-Original Message- From: L_U_I_Z [mailto:[EMAIL PROTECTED]] Sent: Monday, September 10, 2001 9:08 PM To: [EMAIL PROTECTED] I'm developing an application and I have to choose a good database server. I guess that's not the only choice... I'm considering MS SQL Server and MySQL. I haven't heard very much about MySQL, but from I've read on the web I think MySQL is Unix/Linux orientated and works well with PHP. True, but MySQL has an exellent ODBC module as well. It's called MyODBC. I'm going to use a NT platform, with the IIS as web server, and I wanted to use ASP. Does MySQL fit good with IIS and ASP? Now, with this env, you want to check out how big your application might become and shed light on aspects like scalability, ease of backup and restore, etc. Especially Microsoft made some very good progress in this area with MS SQL 2000... OTOH, MySQL is very simple to backup / restore. MySQL is also quite scalable when it comes to seperation of readers and writers (replication). Now, back to your question. As far as my experience is concerned, the Microsoft products work very well if left in a Microsoft-Products-Only-Environment. The big problem that remains is that you need to understand how to install the products in order to guarantee long life time. I don't know about performance of IIS/MySQL vs IIS/SQLServer2000, but I guess MS has the top hand here as well. OTOH, if your choice was somewhat free, I'ld rather use Apache/PHP/MySQL combination: 1st: Cheap Solution (OS + Web Server + DB all for free...) 2nd: Proven Record of Quality (PHP is the most widely used language in Server Side Scripting...; Apache has a proven record of being the most used web server...) 3rd: Yahoo uses MySQL for certain (if not all) areas, and they seem quite happy. 4th: (From my own experience) MySQL virtually never crashes... last but not least: Monty and Team, and this list are very actively participating in helping people out with their problems.

Re: Still Searching for Accent solution - MySQL 3.23
Joshua, I'm not really asking for a new feature. I'm just trying to get the accent insensitive search to work. If you look at the 3.23 Change Log http://www.mysql.com/doc/N/e/News-3.23.0.html the ninth bullet says: Changed LIKE character comparison to behave as =; This means that 'e' LIKE ''e' (if the line doesn't display correctly, the latter 'e' means a French 'e' with a dot above) is now true. So, I'm still thinking my configuration is messed up or something. Brian While I am not saying that a search feature should not be made for this, I will say that 'é' and 'e' have different values, and thus wouldn't match... Perhaps you could substitue a regular expression style search w/more intelligence in your code, for each case where you may want to see an accented character? On Monday 10 September 2001 01:00 pm, you wrote: Hello, I'm still having problems with MySQL 3.23 being accent sensitive during searches.

Re: 'localhost' problem
I had the same problem with suse 7.2. I see that the path to mysql.sock
is /var/lib/mysql/mysql.sock. this location of mysql.sock was a leftover
from the mysql that i installed from the distribution. the downloaded
version though stores the mysql.sock in /tmp/mysql.sock - i had to tell
a few of my programs to look for it there. may you need to add a line in
your php program to look for it there

Subject: 'localhost' problem
hello all,
i am running mysql on a red hat linux v7.0 box.
when i
am trying to connect to the mysql database to read
a
table that is present in the mysql database i am
facing a strange problem. i am able to get into
the
database(named 'newone') to read the table (named
'namelist') from the command line on the machine
that
is running mysql in any of the following ways:
# mysql -u myname -p mypassword
# mysql -u myname -p mypassword -h localhost
# mysql -u myname -p mypassword -h mydomain.edu
All these 3 commands are successful, without
returning
an error.
So i have created a php file named 'namelist.php'
to
read this 'namelist' table, which reads like the
following:
html
head
titleName List/title
/head
body
?php
mysql_connect ('localhost','myname','mypassword')
or
die ('bUnable to connect to the database/b');
mysql_select_db ('newone') or die ('bUnable to
connect to the database/b');
$result = mysql_query (select * from namelist);
printf (First Name: %sbr\n,
mysql_result($result,
0, firstname));
printf (Last Name: %sbr\n,
mysql_result($result,
0, lastname));
?
/body
/html
when i run this php script from the browser, it is
producing the following error:
Warning: MySQL Connection Failed: Can't connect to
local MySQL server through socket
'/var/lib/mysql/mysql.sock' (111) in
/var/www/html/namelist.php on line 7
Unable to connect to the database
But if change the 'localhost' to 'mydomain.edu' in
line 7 it shows the contents of the table on the
browser without any glitch. My question is
eventhough
if it doesn't complain any thing from the command
line
when i specify '-h localhost', why it returns the
above error when i run the script in a browser? i
am
able to reach the index.html page from the browser
by
typing any of the following, on the same machine:
127.0.01
localhost
mydomain.edu
138.xx.xx.xx --my ip address
Can any one please help me with this.

Seemingly Strange Variable Behavior
I ran into this and was hoping someone on this list can explain this behavior to me. Lets say I have the table table which has id and name, and five rows of data. I am using the query select table.*,if(@count,@count:=@count+1,@count:=1) as count, from table; What I get is id, name, and five rows of 1's under count. Now If I do set @count=NULL; select table.*,if(@count,@count:=@count+1,@count:=1) as count, from table; the count column has 1,2,3,4,5 When I do select @count immediately upon opening MySQL it returns NULL. So why do I get the expected result when I do set @count=NULL; but an entire column of 1's when I don't... even though @count returns NULL?

Logically, what I would like to do is: Update tbl1 set x1 = x2 where y1 = y2; But this won't work because x1 and x2 are from different tables, as are y1 and y2.

my.cnf optimization question ..
Basic (maybe?) question on some optimal variables for MySQLd's my.cnf configuration .. Right now, I have three MySQL servers, each with 2 GB ram, dual-CPU P3 1ghz. They average around 500 connections/second at any given time, two have a master/slave setup. MySQL is prettty much the only thing running, nice'd at -20 on a Patched Linux 2.4.9 along w/patched glibc 2.2.4 (LinuxThreads patches). Its run smoothly when I tested it w/~4000 connections and didn't skip a beat. The question basically goes with, I'm expecting to get around 1-2,000 connections/second on average on the systems, using a modified 'my-huge.cnf' from the distribution. No InnoDB, BDB, or overly huge blobs being used. On average each query joins w/about 4 tables on primary/unique indexes where possible. Any changes for this many connections/ram that would be suggested?

Re: Copying data from one table to another.
Will this actually work? Because I can't select from the table into which I'm inserting. Also I don't want to insert. I want to update a bunch of records that already exist. Here is exactly what I want to do. I have two tables set up that I'm dealing with right now. One is the main information table, and one is a table that I set up from a filemaker export. These are tables with information about a bunch of centers our company has, and the information I'm dealing with will be the sponsors field and the zip code. Basically I want to find a record in the export table, and then take the sponsors info from that row and insert it into the sponsors slot in the other row in the other table that correspond to the same zip code. The code I would use is logically like this. But it seems I can't get the SQL right. I do this, and it tells me it can't find my table. Update tblOrganizations set OrgSponsors = tblCenters.CenterSponsors where OrgZip like tblCenters. CenterZip; Any help would really be great.

load level on linux mysql server out of control
I'm running mysql 3.23.41 on a PIII 800 Mhz machine with 512MB RAM, linux kernel 2.4.7, dedicated machine (ie, not running anything other than MySQL). I've been running mysql in a production environment for nearly 2 years, moderately hit (500,000 - 800,000 database connects per day) with no problems until very recently, and I'm trying to figure out what's going on. I just installed the 3.23.41 from source about 2 weeks ago, and fairly shortly thereafter I started seeing my load levels increase dramatically. This was on a faster machine with 1GB RAM...last week the hard drive developed bad sectors on a part of the disk where one of my larger and more frequently written tables lived, and that machine died a horrible death. So I chalked the load level increase up to bad hard drive, put the above-described machine in its place, and the load levels went thru the roof again. Ran isamchk and myisamchk -r on all problem tables. Verified the disk integrity...but yesterday the *new* disk failed at a block containing another big and heavily hit table started with the bad blocks...caught this one in time and moved the table someplace else. Two disks in one week makes me think of power fluctuations, and I'm wondering if this could be causing me to think the problem is MySQL and really it's a power spike during a table write?? And I wouldn't be seeing the same thing on the web server because it's not written to very often, unlike the mysql server... I'm having a lot of trouble tracing the origin of the problem -- sometimes it seems that accessing a particular large table is causing it, sometimes it seems that a combination of factors is causing it. Regardless, what I observe is that within 1 minute my load level climbs from between 2 and 4 to over 100, which I have never seen on any *nix system before. The RAM utilization is high, but not over 85%, and the CPU utilization fluctuates of course but stays below 40% user until whatever is causing my problems happens, and then it jumps to 100% and doesn't come down until I kill mysqld and let everything close. The database is being accessed almost entirely by PHP calls from php4.0.6 running with apache 1.3.20, using PHP's built in mysql functions. The web server lives on a different machine.Does anyone know of any problems with PHP and the newer versions of MySQL? What about large table handling on linux? I realise that if the tables aren't constructed properly they could cause problems, but these tables aren't *that* big...the data files are no more than 200Mb. And they seem to be using indexes correctly, and they've been running fine for nearly 2 years. These are mostly ISAM tables, if that makes a difference. This has been going on for the better part of a week now and I'm about out of guesses. We have combed our code for places where database connections aren't closed properly, we've split large tables off and checked indexing, we've even moved a high-volume read-only database onto the webserver itself to help lessen the load, and I don't know what else to do. If anyone can help, it will be greatly appreciated.

Re: my.cnf optimization question ..

Right now, I have three MySQL servers, each with 2 GB ram, dual-CPU P3 1ghz. Nice. :-) They average around 500 connections/second at any given time, two have a master/slave setup. Connections/sec or Queries/sec? That's a lot of connections per second? Can you use persistent connections? It would save a lot of overhead. MySQL is prettty much the only thing running, nice'd at -20 on a Patched Linux 2.4.9 along w/patched glibc 2.2.4 (LinuxThreads patches). Its run smoothly when I tested it w/~4000 connections and didn't skip a beat. The question basically goes with, I'm expecting to get around 1-2,000 connections/second on average on the systems, using a modified 'my-huge.cnf' from the distribution. Care to share the config file? With that much RAM, there are probably some things you can tweak to make optimal use of the 2GB RAM. But if you've done a lot of that, I won't bother pointing them out (obviously). On average each query joins w/about 4 tables on primary/unique indexes where possible. Any changes for this many connections/ram that would be suggested? How are things looking in SHOW STATUS? Any red flags that you've noticed? Any slow queries? Jeremy -- Jeremy D.

Re: load level on linux mysql server out of control
At 01:46 11.09.01, you wrote: I'm having a lot of trouble tracing the origin of the problem -- sometimes it seems that accessing a particular large table is causing it, sometimes it seems that a combination of factors is causing it. Regardless, what I observe is that within 1 minute my load level climbs from between 2 and 4 to over 100, which I have never seen on any *nix system before. The RAM utilization is high, but not over 85%, and the CPU utilization fluctuates of course but stays below 40% user until whatever is causing my problems happens, and then it jumps to 100% and doesn't come down until I kill mysqld and let everything close. hi, same problem here. mysql 3.23.41, apache 1.3.20, php 4.0.6, kernel 2.2.19, debian system. 1GHz PIII 512MB. load 200. my fix for now till i have a better idea is to restrict the number of apache children to 60 which keeps the load 20. which is horrible nevertheless. and extremely slow for the users at times. the load normalizes (to something 4-ish, which is still pretty high for ~50q/s) again after ~15min. if you find out anything about that problem, PLEASE tell me. i´m searching for ~3 weeks and i´m not smarter in the least. and it sucks :-( at least i didn´t have that harddisk failures. yet. but then, it´s a colo machine so power should be fine. yes, dear mailing list, i know you told me my queries are, well, suboptimal. but i´m not quite sure about that. more tomorrow:-) greetings henning - 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?

Strange insert behavior with larger tables
This weekend I wanted to better characterize how different key configurations affect the way rows are inserted. I ran into some behavior I can't understand: I created a prototype table to allow me to track the number of events that occur on a particular day. Events are described with three integer fields and a type field which can be 0-3. The table then is: date date not null, type tinyint not null, val1 int not null, val2 int not null, val3 int not null, occurrences int not null. I then added a primary key (date, type, val1, val2, val3) because I want to ensure that I have only one row for each combination of these items. I ran these benchmarks on my Win2K box (real environment Linux, just testing here). I wrote a program which inserts a number of rows for each day (with unique type, val1, val2, val3 values). type can have the values 0-3, and val1-3 can be between 0 and 24,000. I found that I could insert about 10,000 rows in about 4-5 seconds (512 M RAM, IDE drives UDMA). It consistently took between 4-7 seconds to insert 10,000 rows until I got up to about 2 million rows. Around that time it started to slow down significantly taking about 10 seconds to insert 10,000 rows. By the time I got up to about 15 million rows, it was taking over 30-40 seconds to insert 10,000 rows. The strange thing, however is that as soon as I changed to a new day (the first element in my primary key) rows began inserting very quickly again. I was right back where I started-getting 10,000 rows in only 4-5 seconds. I guessed that the key was the limiting factor here somehow, so I tried my test again, but first dropped the primary key. Without the key I no longer have a guarantee of uniqueness, but I'm able to insert 10,000 rows every 3-4 seconds consistently well over 5 million for a single day. Therefore, it appears to be the key which is so dramatically slowing inserts as I get more rows. Curious, I ran perfmon on my machine and repeated the experiment. I observed the following: - Time to insert quadruples (from 4-5 sec/10,000 rows to 20-25 sec/10,000 rows) - Processor usage drops 2/3s (100% usage to 37% usage) - Amount written to disk/sec drop 4 fold (~400 bytes/sec to ~200 bytes/sec) - Number of writes/sec almost double (232 to 385) - Avg. amount of data with each write drops 4 fold (19000 bytes to 5000 bytes) - Avg. time to do each write stays constant (.004 sec) - The machine is NOT swapping page files on and off the disk. To summarize, at first when doing these inserts the machine is CPU bound. It is using 100% of CPU resources. However, as the number of rows for the day we are inserting increases, the machine becomes severely IO bound. This seems to be due to the fact that although the number of writes to the disk almost double, the average amount of data drops 4 fold as does the amount of data being written with each byte. Basically we switch from doing fewer larger writes and being CPU bound, to doing many many more tiny writes that the disk can't keep up with. At first (before seeing the perfmon data) I though this might have something to do with the key being held in a buffer until it grew too large. Then is when we'd start to see the performance slow down. However, I have not been able to find a value of the key buffer which really changes performance. I've tried values between 3M and 70M, with very similar results. I do get slightly poorer performance with the 3M than 70M (starts slowing down around 1.3 million instead of 2 million) but nothing that I think accounts for this problem. Why do inserts slow down once I get around two million, and I don't seem to be able to affect this by tweaking buffer sizes? Why do inserts then speed up again when switching to a new value for date, but slow down again once I get close to 2 million for the new value? I've included below a dump of variables.

Looking for a Data entry program for mysql...
Hi all, I am looking for a freeware-shareware pgm for data entry, on win32 for a mysql database on Linux(not that it matters I guess), that would allow me to feed data with drop down or list box field. Any suggestions???

Re: help with mysql.sock error
su nobody ls -l /var/lib/mysql/mysql.sock Whatever user is trying to get it [such as nobody for a web server usually or the user]- make sure the user can access the file.
