Re: Please Help. selectcol_arrayref problem
Nope. That's just granting replication privileges so it can read updates
on all tables on all databases. It cannot select anything.
Why are you trying to connect with a replication slave user?

Re: please help reading DB deadlock notice
Nikita Tovstoles [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Do both of your SELECT statements use the same index (`token`) when setting locks on the rows? My guess is that the situation is as follows. TX2: SELECT ... WHERE id = ... FOR UPDATE TX2 sets an exclusive lock for a row on PRIMARY index. TX1: SELECT ... WHERE token = ... FOR UPDATE TX1 tries to acquire X-lock for a row in `token` index, which succedes. This however requires also a lock on PRIMARY, but the corresponding row on that index is already locked by TX2. TX1 waits. TX2: DELETE ... WHERE id = ... TX2 tries to delete the row. This of course requires the removal of its presence in the indxexes, including `token`, but because of the earlier exclusive lock set by TX1 this cannot be accomplished without waiting for the lock to be freed. TX2 waits. Hence, the deadlock. I'm wondering if granting X-locks for the secondary indexes could not be delayed until such lock on the primary key is acquired...?

Re: please help optimize this query
Thank you for your help. I will try using chars instead of
varchars. That should be fairly
easy to try. I already do have a table for symbols, though the key
is varchar not integer.
I was using shares and value as varchar because there was some weird
rounding happening when I
used decimal, or floats. It seemed easier to keep them as
character. Also the date is part
of the key since for different days there is different values as the
stock market changes.
I will try char though and see if that makes it faster.
Thank you.

When you drop a database, it deletes the table files and then tries to delete the directory. If the directory remains, even if it is empty, it still looks like a databbase to MySQL. So check the directory that corresponds to this troublesome database for unusual permissions or content (such as some files other than MySQL's table files) that may be preventing the deletion of the directory. (Check /etc/my.cnf for the location of your database directories. RedHat usually puts them in /var/lib/mysql.)

Although this is something for a PHP mailing list of forum, I'll try to
give you some pointers.
I assume that you first used mysql_connect() to connect to the MySQL db.
mysql_query() returns FALSE if the query failed for some reason. In that
case you can use mysql_error() to retrieve the error message.
$result = mysql_query($dbQuery);
if (!$result) die('Query failed: ' . mysql_error());
Checking isset() is useless, since $result is always set (either with
false, true or the result resource of the query).
http://www.php.net/manual/en/ref.mysql.php contains an example which
shows all the steps you need to set up a connection and run a query.

Posted by gogman on Monday May 5 2003, @10:42am on the mysql website:

It's not clear to me that this is entirely accurate (Google, for example, is

don't think web search engine front ends are particularly relevant in any case.

('OR' would be the default setting so as to not break older code)
With a 'AND' default 'OR' would have to be explicit. Example: 'dog cat' = 'dog
AND cat', 'dog OR cat' - requires 'OR' to be set.
Performance tests are indicating a 5-7 times increase in search speed
with AND vs OR statements.

I have done some searches on google and found several people wanting to do the
same... but no solutions.
Is there still no solution for this? Every large searchengine works like
this.
Why do you *need* this? More to the point, why should mysql do this?
Honestly, I think you are confusing the user interface, the application, and
the back end. Your user interface is free to include a search box where the
user can type 'dog cat' with the expectation that only documents containing
both (AND) will be returned. Your application needs to parse the request
and send the proper query to mysql (the back end). Mysql is just a useful
tool. It stores your data and provides various forms of full-text searching:
Relevance scoring -
WHERE MATCH (doc, description) AGAINST ('dog cat')
OR searches -
WHERE MATCH (doc, description) AGAINST ('dog cat' IN BOOLEAN MODE)
AND searches -
WHERE MATCH (doc, description) AGAINST ('+dog +cat' IN BOOLEAN MODE)
Given these choices, I'm not sure what difference it makes what the default
is. You surely don't propose to pass unmodified user input to mysql, as
that's not a good idea (see SQL injection
http://www.google.com/search?q=SQL+injection). If you want AND searches,
simply have your app add the + signs to the user input as it builds the
query to send to mysql.
If you are determined to change mysql's default behavior, then Sergei has
already given a solution earlier in this thread: swap the '+' and ' ' in the
ft_boolean_syntax variable. The only objection raised to this was the
suggestion that if the user prepends a '+' to a word, it becomes optional
(OR instead of AND), but that's a moot point, as your app will, of course,
strip the '+' when parsing the user's input.

You want to put the space first (for must be present words)

Re: Please help me: Boolean fulltext searches, AND instead of OR
I couldn't find much on the variable you were trying to change.
Although it may have changed and now be called ft_boolean_syntax. But
that still won't help you since it doesn't appear to have an option to
change the default separator.
I think you will need to add the + to each word if you want the AND
behavior. Why are you so averse to parsing? It would make it easier for
the user to input search terms.
If it's helpful, below is some php code I use for parsing search
phrases entered by users. It adds + and * based on quotes or
independent words. I wrote it a long time ago and it problem needs to
be looked at to make it better, but it's worked for me for a while now.
It will give you the AND behavior you are looking for.
function prepFullTextSearch($searchVal) {
//Split words into list
$word_List = explode(' ',trim($searchVal));
//Step through word list to get search phrases
$i = 0;
$isPhrase= false;
foreach($word_List as $word) {
$searchItems[$i] = trim( ($isPhrase?$searchItems[$i].' '.$word:$word)
);
//Check for start of Phrase
if(substr($searchItems[$i],0,1) == '') {
$isPhrase = true;
}
//If not building a phrase, append wildcard (*) to end of word
if(!$isPhrase) {
$searchItems[$i] .= '*';
$i++;
}
//Check for end of Phrase
if(substr($searchItems[$i],-1) == '') {
$isPhrase = false;
$i++;
}
}
$searchVal= '+'.implode(' +',$searchItems);
return $searchVal;
}

I found this:
set-variable = ft_boolean_default='AND'
SET ft_boolean_default = 'AND'
But it does not work, everything would be sooo much easier if this was
possible.
black cat is only an example and the real query comes from user
input. So it can be anything like +cat -dog +big nose -horse white
black -red
so parsing the input is not what i want, i just want to change the
default word separator to AND instead of OR.
Now i´m running 4.1.10 and also tried with 4.0.24
Please help me, there must be a way to change this?!?!

Re: Please help with query to show duplicate addresses... TIA!
If you are using 4.1, you can look into the GROUP_CONCAT function. Otherwise, try a self join like this: SELECT A.LastName,A.OrderNum,B.OrderNum FROM Orders AS A LEFT JOIN Orders AS B ON A.LastName=B.LastName WHERE A.OrderNum!=B.OrderNum ORDER BY A.LastName That joins the Order table with itself on LastName and filters out the non-duplicates, since there will always be at least one match, by filtering out Order Numbers that match for the duplicate last names. It will output something like this: A.LastName A.Order B.OrderNum - smith 1 2 smith 1 3 jones 5 10 jones 5 12 jones 5 23 I don't know if the not equal syntax I used != is valid for your version of MySQL. I know it works in 4.1. That shows that smith has order 1,2, and 3. Jones has 5,10,12 and 23.

Re: Please help me optimize a MySQL server.
Something that small shouldn't really need optimizing. What is the size of your data (mb?, gb?) and what does your query look like? If you are doing a wild card search on a large text field without a full text index, then those times may be the best you're going to get. Many times it's about optimizing your query statement or you indexes rather than MySQL settings. For instance, I have a test machine (Mac G4 400Mhz, 512MB, MySQL 4.0.18) that does a three table join with each table having just over 100,000 rows. My initial query took about 12 seconds, but changing my query statement around a little I got it to just under 1 second. Which is pretty good considering the hardware it's on. What does you explain for the query look like? It's probably doing a full table scan, which means you're bottleneck is the disk.

Re: Please help me optimize a MySQL server.
I wouldn't upgrade until you know where the bottleneck is (CPU, disk, network, or RAM). Since you are using professional software, I wouldn't try to change the queries. Have you made changes to your my.cnf file? Since you have enough ram to hold all the data, ram is probably not your bottleneck. The question is whether you have your system configured to use it. I forget if phpbb and phpnuke use PEAR::DB to access the underlying database. If they do, there is a certain amount of overhead involved that you just can't get around without changing the database access code to use native calls. Are your database and web server on the same machine (a security no-no, but performance yes-yes)? If they are on separate machines, make sure you have a fast connection between them, at least 100MB and make sure it's full duplex.

But the server is down all right (at least to me). Then I logged out in my connection as ginger to mysql server. Then I changed the variables in /etc/my.cnf and try to bring up the server using 'safe_mysqld --user=root '.

Re: Please help with syntax for mysqldump

Re: Please help with syntax for mysqldump
mysqldump is run at the system command-line, not within the mysql client environment. This is most likely to be my problem then. I assumed that what is called the system command line to be the mysql client environment. The tutorial book that I have been going through instructs me to issue this command in the start menus run dialogue box: C:\Windows\Desktop cd C:\mysql\bin and from there I have issued all commands in the black window. Is this not the command line, and if not, what is? Sorry for my ignorance, I am still a beginner.

Open a new Command Prompt in windows (something like Start-Programs-Accessories-Command Prompt) Then type cd c:\mysql assuming that is where you installed MySQL then type : bin\mysqldump -uusername -ppassword dbname csi_db01 c:\csi_db01.sql This will create a file called csi_db01.sql in the base of your C: drive that contains all the SQL needed to recreate your table.

Assuming that Iknow the codes for each characters (found at the above point) how can I putthese codes in the three tables within the latin2.conf file?- Original Message -From: "Primaria Falticeni" [EMAIL PROTECTED]To: "MySQL LIST" [EMAIL PROTECTED]Sent: Monday, July 28, 2003 10:00 PMSubject: Please HELP Romanian charset Collate in MySQL Hello, Simply I made a table with romanian characters "aAîÎâÂsStT".

RE: Please help me!
As this is really a PHP specific question, you may get a better response on the PHP
general mailing list at http://www.php.net/mailing-lists.php
Anyway, if my limited experience in PHP serves correctly, you may need to call
echo(mysql_error()); near the potentially troublesome code.

Re: Please help: Can not insert binary data larger than 16 megabytes
Try using 'max_allowed_packet=16M' instead of your current value. You may also find help by reviewing the below. http://www.mysql.com/doc/en/Packet_too_large.html Is there a reason you are including the BLOBs in the database instead of just linking via it? I know it's generally considered better practice to do the latter.

Stewart, Yesterday I posted the message listed below. I have some more information. We have found the command that pushes our database over the edge! It is: SHOW VARIABLES; All other db commands work (such as SHOW VARIABLES %a;) except for: SHOW VARIABLES % This should be SHOW VARIABLES LIKE '%'. I tested all variants with 4.0.10, no problems. SHOW VARIABLES '%' gives me error 1064, as should be. Does anyone have any idea why this could be happening?

I've got a web page (php) that's displaying the images available for a
particular product using a query like:
select products.product_name, images.fg_number, images.image_name,
images.thumbnail, images.image_path, images.color_depth,
images.width_inches, images.height_inches, images.resolution,
images.filesize, images.filetype, images.notes from products, images where
products.fg_number ='$fg_number' and images.fg_number = products.fg_number;
Which works fine, as long as there is data in the images table
corresponding to a product, but in the case where there are no images
related to a particular fg_number, the query returns an empty set.
What I'd like to get, is the products.product_name regardless of weather
there are any corresponding images, so the variable $product_name will have
a value on the php page and I can generate a message something like sorry
there are no images of '$product_name' available...
I can see how to do this with 2 queries, but shouldn't I be able to do it
with one? and wouldn't I take a performance hit by running more than one
query per page?

Re: Please Help
Files never get smaller. They can only grow. Deleteing a record marks the area used as available, but does not remove it from the file. I believe you will have to optimize the table to pack out the unused records. This is another good argument for storing images in the filesystem, and only their locations in the database.

No you don't need them if you don't want that the tool queries the server for to see the variables, databases/tables and make reports, in another words them are used for to connect to the server, not for start/stop the server. However you need to consider that the my.ini file is locates at WinDir directory (WINNT\Windows) and for security you need to protect that directory with the Windows directives, in this case the my.ini file even in plain text should be protected.

RE: Please Help! MySql 4.01/PhP 4.06 looking for Libmysqlclient.so.10?
PHP is looking for the client library that gets installed with MySQL 3.23.4+. Now, you can try a QUICK fix that might not work, but it's worth a shot. Go to the directory that has the libmysqlclient.so.11 file and type the following: ln -s libmysqlclient.so.11 libmysqlclient.so.10 That should create the file libmysqlclient.so.10 that links to ...so.11. If the client library is vastly different, though, it might not work. If it doesn't work, you should go uninstall PHP, go to the directory where everything was being compiled, edit the necessary files to have PHP use libmysqlclient.so.11 instead (this might be in the Makefile - but be sure you run a make clean first), and recompile. I don't know how different the PHP RPM will be, but there should be a place where you can change the reference to libmysqlclient. I use FreeBSD's ports system and it has a special configure script that creates a little addon to the Makefile that specifies the library version numbers like 10 or 11, and you can change that file before compiling. - Jonathan -Original Message- From: Ronald Arenas [mailto:[EMAIL PROTECTED]] Sent: Friday, March 01, 2002 12:19 PM To: Mysql Subject: Please Help!
