Hi Doug, First, thanks for the idea. Well, We solved the problem using 2 selects. Actually I was doing what you suggested. I used a "little" select using limit 0,10 and got the last DATE value. So, with this value I can construct the WHERE part easily of the second select. it's working fine, but, I just wanted to optimize it trying to make it with only one select. I tried to use de LAST_INDEX() function, that catch the last inserted AUTO_INCREMENT, but I could'nt do it!. I'm trying to make some kind of REGEXP but I'm almost giving up. Some friend of mine told me that TWO selects aren't recommended, but in this case I can't see no other way to do this.
If you have any other idea, it will be very helpfull. Thanks!

(1) Put the first result set into a temp table, on which you could execute subsequent queries, or (2) Use php to construct an array of the result rows, and then use php's array-sorting functions, but I'm not sure why you couldn't... (3) Go back to the db for fresh data with a WHERE clause modification based on user input. - Doug At 07:02 PM 12/3/2002 -0200, you wrote: >Hi Jim and others that tried to help me! >Thanks for any kind os answer. > > Well, the SQL command that you suggested don't work for me.
