Hi, PROBLEM : it's a query performance problem. There is several inner join in my query (on 5 table and 1 view and 1 user function) return 23000 lines. -> Select with 30 columns (60 with select *) CONFIG : Tests have been made on 2 pc with same hardware : -> PIV Dual Core D920 -> Same harddrive -> SQL Serveur 2K SP4 version : 8.00.2039 -> Same database WHAT: -> On pc without problem : execution time 1850ms -> On pc with problem : Select "columns_list" : 17854ms Select * : 3753ms Select "columns_list" without join on view and user funtion : 8000ms Select * without join on view and user funtion : 3800ms More test on third pc running query on the 2 other: 3rd pc on pc without problem : 8500ms 3rd pc on pc with problem : 8500ms so problem seems disapear when run remotely. TRY TO RESOLVE : Check database (restore same on 2 pc) Reinstall SQL Server et SP4 If you have any idea, she is welcome. Thanks in advance.
