You have a few ways to do this. What's happening here is that you do a comparison in a string context, which means that it will sort according to the ascii values, and 1 comes before 8. To sort the way you want you need to specify to MySQL that you want to do it in a numeric context. You have two

Re: can't find FULLTEXT index

2003-12-03 Thread Tobias Asplund
If you do a fulltext search on multiple columns at once, there must be a combined fulltext index on this exact set of columns. Just having an index on them individually will not work. On Wed, 3 Dec 2003, Mirza wrote: > Hi, > > I have error 1191 "can't find fulltext index matching the column li

I think that http://www.mysql.com/doc/en/example-Maximum-column-group-row.html covers your problem here. You either have to solve it with Temporary tables, the MAX-Concat trick (in the url above) or a subquery (which will be more inefficient than the other two options). On Thu, 20 Nov 2003, Yve

Re: Question on SELECT support

2003-10-17 Thread Tobias Asplund
MySQL doesn't support TOP, however, there's a LIMIT syntax for MySQL that roughly does the same thing: http://www.mysql.com/doc/en/SELECT.html for a brief explanation. In your example what you are looking for is: SELECT DateCreatedField FROM my_table ORDER BY DateCreatedField DESC LIMIT 10;

Re: mysql max

2003-10-17 Thread Tobias Asplund
It depends on your filesystem's and OS's max-size of a file in its filesystem. HOWEVER, there are a few ways you can get around this. You can use InnoDB tables, or read about RAID types here: http://www.mysql.com/doc/en/CREATE_TABLE.html (almost at the bottom of the page). You can also use MERGE
