RE: Error Code 28
Morning Jorg, Thanks for the reply. The limit clause restricts the data returned, but not the data examined. You ask the server to examine a certain set of rows (where ...), sort it (order by ...), and then to return a limited number of these rows (limit ...). As the data only exist in some other order and you (probably) do not have a way to access them in the order desired (or do you have an index on bluetooth_session.created?), the server must first sort all qualifying rows. This is where it needs so much space. This makes perfect sense, I see what you mean about the fact that the data has to effectively be collated in its entirety before it is ordered and limited, that's a very fair statement. Somebody else has already commented on the limit clause you use, I need not repeat that. They did indeed, I hadn't noticed this myself, the SQL is produced by an ORM so I'll examine how I'm using that, thanks to all who pointed that one out. I strongly suspect an index on bluetooth_session.created would help, both in evaluating the where condition and in avoiding the sort for order by, and so both reduce the time and avoid the temp space. I can see your point on this, I've not worked with index's at all at this point in time so I'll give them a shot and see what difference that makes, the created date definitely makes a very strong candidate as this is generally how the data is queried, so that'll be my first index, I also regularly query on the address column so I'll be sure to try indexing that too. Disclaimer: Not tested, not checked - just assuming. I really appreciate the suggestions, I certainly see the logic in them, let's hope they bare fruit :-) Cheers, Heston -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Error Code 28
you can make mysql to use memory for creating temp files rather than disk set sort_buffer_size=1024*1024*100; and try your query. Also the size of the columns is based on the db engine ur using, i dont remember the exact number, i will denfinitly find it in mysql docs. regards anandkl On 10/22/08, Heston James - Cold Beans [EMAIL PROTECTED] wrote: Hi Rob, Thanks for getting back to me on this.

RE: Error Code 28
Heston, What happens if you remove the Order By clause from the query? Does the file size drop? Also why are you using LIMIT 1, 699? The 1 skips the first row because that is the offset. If you just want the first 700 rows then use Limit 700 Mike At 06:29 AM 10/22/2008, you wrote: Hi Rob, Thanks for getting back to me on this.

Re: Error Code 28?
Hi ED, thats a number to big for me yet. Sorry. I guess thats better posted to the mailing list. The best I can do is an educated guess (or whatever thats called).

RE: Error code 28: No space left on device
What will happen on Error code 28: No space left on device? Will mysql crash down?... Will there be posibility of reading data from tables? I saw this error on one of my servers not too long ago. MySQL keeps running but seemingly refuses to do SELECTs on any tables. Upon freeing some space those same SELECTs went through fine without a restart of mysqld. I believe the default my.cnf uses /tmp for its temporary files. If this partition is full you may either free some space within it or alternatively specify a different location for MySQL's temporary files. See the tmpdir setting in my.cnf. e.g.: tmpdir = /usr/tmp/ Ron Jamison - 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?
