Re: MySQL users.
Check also the other tables in the `mysql` database such as db and host to make sure that there are no entries of that user with 'locahost' as host. If you created the entries earlier, there is a chance that the entries are still there with the localhost entry. Or simply delete everything in DB table and restart. Hope this helps.

Subject: Retrieving info from a Joined column
We have a column in our table that has
new info added each time using a JOIN function.
The data sample makes me rather think
update table set field=CONCATE(field,':','more')
The data is separated using a : separator.
This doesn't answer your question...
However, note that in most instances using columns with multiple
values is a bad idea in a relational database. If possible, you'd be
better off with a design that does not require multiple values in a
single column.
I'ld second that. However, to maintain compatible output to your Perl script
consider GROUP_CONCAT http://www.mysql.com/doc/en/GROUP-BY-Functions.html
How does one retrieve this info from the colomn and put it
into list format,
In Perl there is 'split'; takes a 'field delimiter and a string to return an
array of strings.
or check for duplicates,
Using 'where NOT( field LIKE '9807:' and field LIKE ':9807' and field LIKE
':9807:' ' ) within your UPDATE should do the tric
or do a search in the column for a certan string.
On an existing data base you might consider LIKE
... where field LIKE '9807:' and field LIKE ':9807' and field LIKE ':9807:'
Adding a ':' to both the beginning and end of the content would obsolete the
first and second part of the above.
However, you need to 'shift' and 'pop' a pair of empty fields in Perl AND
change to CONCATE(field,'more',':')

I raise the question because the vendor that provides the utility we use to create our installation package claims that MySQL uses non-standard commands for installing and removing services. As a result, they say, we cannot expect their program to install or remove the service. The irony is ... their program **does** install the service. It just can't stop the service and remove it. We use a third-party installer because we package the six databases our software suite requires with MySQL. I'm not sure I'm getting what you're after, but here's what MySQL does: shell mysqld --install # installs a service with the name Mysql shell mysqld --install MyMySQL # installs a service with the name MyMySQL shell mysqld --remove # removes a service with the default name (Mysql) shell NET START Mysql # starts the service called Mysql shell NET STOP Mysql # stops the service called Mysql shell would be something like c:\mysql\bin, depending on where you've installed MySQL. mysqld may as well be a different flavour of the MySQL server, e.g. mysqld-max-nt. What --install does is write a couple of entries to the Windows registry, and --remove will delete those entries. I don't know whether that procedure is considered standard on Windows systems or not; if it isn't, you might want to have a look at what --install actually writes, and then use a standard way of writing those entries (using a .reg file or whatever).

Also dual processors will speed things up some, perhaps by 30%. m 2) Is the problem related to reads or writes to the database? What's the easiest way to check? Chuck may be right in that your joins are not using indexes. Use Explain select to see which indexes are being used for your joins. If indexes are being used, then investigate: Show Status or Show Status like key% to get just some of the lines. Look for Handler_Write which shows the number of times a write was performed Max_Used_Connections, If Opened_Tables is large then increase table cache size. Select_Full_Joins: The number of joins that did not use indexes Select_Scan: Number of joins that did a full scan of the first table Table_Locks_Waited: # of times the operation had to wait to get a table lock Also look at join_buffer_size which is the size of buffer used in non-index joins. If for some reason you can't use an index in the join, you may have to change this setting. Needless to say, you want to use an index if at all possible when running on a webserver. Mike m 2a) If the problem is with reads, I'd recommend put a Limit 10 or m 20 on your Select statements so they don't pull too much data at one time. m Chances are they are only going to look at the first 10 choices anyway. To m get the next page, increment the page # and increment Offset m which=(PageNum-1)*RowsPerPage. m 2b) If the problem is with writing to MyISAM tables have you m looked at InnoDb for the tables with a heavy # of updates? m 3) I've also found that 20%-25% of the CPU time is spent loading m the PHP script from the disk. Every time the PHP page loads, it needs to m re-read the PHP file(s) from disk. You can speed this up considerably by m creating a small RAM drive and put your PHP script files on that. Change m your PHP configuration to look for the RAM disk first. m 4) You can try a PHP accelerator. There are several free ones out m there. Yeah I will try this. m 5) You can of course replicate the data to 2 machines and use a m load balancer to handle read queries. Updates would be made to one database. m 6) If all else fails, shave your head and tell the ladies you are m Vin Diesel looking for a new co-star in XXX-2 and you'll forget all about m your MySQL problem. g Yes this sounds the best solution, I wish I could forget! m Mike Thanks for the suggestions -- Best regards, Nevmailto:[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Hi I am new to MySQL connector J. I do not know how to install it. I just downloaded the .zip file and I am using XP Home. I want to use it with tomcat which is already running OK.

RE: Installing MySQL on Fedora
As far as I am aware mysqladmin is a server control program so it comes with the mysql-server RPM .. The one listed below is purely a mysql client and shared library package. Regards, Phil. From: Todd Cary [mailto:[EMAIL PROTECTED] Sent: 30 November 2003 01:02 To: [EMAIL PROTECTED] Subject: Installing MySQL on Fedora I tried installing MySQL on Fedora and all seemed to go fine, but there is no mysqladmin. Have I missed something here? And I am not sure where the mysql executable resides. The version is MySQL-3.23.58-1.i386.rpm Todd -- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
