Re: How to auto repair db on hosting with quota
I won't convert thread style, so, i'm top-posting :) All this would be great if it worked. The main problem is that temporary directory option for mysqld iS NOT USED while doing table repair. All files while repairing tables are placed in the same directoty with the same owner and group as the original database files (i mean, for example, .TMD files which can be huge!). So, i am currenctly stuck with no solultion to the problem. -- Artem Russell E Glaue wrote: Using Quota on Unix, you can specify a different quota soft_limit for temporary space.

With MySQL temp dir set to /tmp, and a soft/hard quota as 10MB/300MB, the recovery should occur successfully. And going above the soft_limit gives the user X amount of days to get back down below the soft_limit. And the user cannot go above the hard_limit. You can set the soft_limit recovery days to like 1 day. They can go over the 10MB soft_limit for 1 day, up to the hard_limit of 300MB, but after one day the temp files will be deleted until the soft_limit is satisfied.

A use for REGEXP, I think.
I have a field in a DB that contains something like lvlscore4:4493,lvlscore5:3232,lvlscore6:6128 I need to select all records where the lvlscore5: is greater than 3000. I think this can be done using REGEXP but I have read the docs and am non the wiser for it. Can anyone point me in the right direction? -- Thanks David Scott
Re: How to auto repair db on hosting with quota
Hmm.., I thought the temp tables were created in the temp directory. What version of MySQL are you using? Perhaps you can temporarily increase the user's hard_limit, and not increase the soft_limit. When they have finished recovering, you can reset the hard_limit. Or perhaps it is possible to copy the corrupted database to the temp directory (with increased hard_limit), perform the recovery there, then copy it back. The data directory does not have to remain in the same location in order to be recoverable. This would be the same as the last e-mailed proposed solution, but with two extra steps to copy back and forth from the temp directory. -RG - Original Message - From: Artem Kuchin [EMAIL PROTECTED] To: Russell E Glaue [EMAIL PROTECTED], mysql@lists.mysql.com Sent: Sunday, December 9, 2007 9:03:45 AM (GMT-0600) America/Chicago Subject: Re: How to auto repair db on hosting with quota I won't convert thread style, so, i'm top-posting :) All this would be great if it worked.

Re: A use for REGEXP, I think.
regex discussion are a little outside of the scope of this list, but I will offer an opinion: You can't do math, no matter how simple, in regular expressions. I have seen many try and fail. While I am sure there are circumstances around how that data got that way, what you really need to do is use the database relationally and decompose that field into data structures instead of strings, then you can do pretty much anything you want. - michael dykman On Dec 9, 2007 12:53 PM, David Scott [EMAIL PROTECTED] wrote: I have a field in a DB that contains something like lvlscore4:4493,lvlscore5:3232,lvlscore6:6128 I need to select all records where the lvlscore5: is greater than 3000.

Insert lecture about correctly normalizing data.
I think what you suggested is the wrong path for a successful outcome.
As far as I can tell the regex engine in mysql only returns a
booleans. http://dev.mysql.com/doc/refman/5.0/en/regexp.html . Someone
correct me if I am wrong.
This would work:
SELECT 'lvlscore4:4493,lvlscore5:3232,lvlscore6:6128',
SUBSTRING('lvlscore4:4493,lvlscore5:3232,lvlscore6:6128',
LOCATE('lvlscore5','lvlscore4:4493,lvlscore5:3232,lvlscore6:6128')+length('lvlscore5')+1,
4
) as 'lvlscore5'
4 is a magic number that will not work if the score is not always of
length 4. If that is the case replacing the last argument of substring
with a bit more logic will sort this problem.

Replication - urgent
Hello All,
I set up replication between 2 servers recently. I just need one db to be
replicated and the SHOW SLAVE STATUS shows this:
Relay_Master_Log_File: gyana01-bin.02
Slave_IO_Running: Yes
Slave_SQL_Running: No
Replicate_Do_DB: tallydb,tallydb
Now the problem is that there is another db named tallydbopextblob and the
tables from this db are also getting replicated as shown in the below line.
Last_Error: Error 'Table 'tallydbopextblob.TBL_EVAL_PITEM_OP_EXT_DETAILS'
doesn't exist' on query. Default database: 'tallydb'. Query: 'INSERT INTO

Why is this happening?

To be clear the regex should work, but it will probably take more work
than what I just suggested. Using what I suggested in the where clause
rather than as shown in the select clause will probably be the easiest
solution.
