Sql query : select max timestamp value from table
I have multiple timestamps values for single ip in a table, I need the max(timestamp)for each ip I select out. example: timestamp ip 2003-09-29 13:20:23 68.209.182.42003-09-29 13:20:44 68.209.182.42003-10-02 12:53:38 68.209.182.42003-10-02 12:35:06 68.75.94.1582003-10-02 12:52:03 68.97.33.69 Thus select distinct ip, max(timestamp) from table group by ip, timestamp; returns every timestamp value per ip. Any ideas on how to get only the max(timestamp) for each ip?
Re: Sql query : select max timestamp value from table
Johan, First, you don't need the distinct. The proper query will return 1 row per ip. Second, take the max(timestamp) out of the group by. That is causing the problem.

Johann, Take the timestamp out of your group by. Cheers, Melanie *** Melanie Caffrey Proximo Consulting Services, Inc.
