>>While you have your answer, the real problem is that SQL Server 2000 always uses ANSI settings for things like datetimes. So

csql = "select * from prestacoes where data_venc <= '2/28/2006 00:00:00'"

should also work. The time portion of the above is optional.

Geez, Dragan, I don't know. And I can't find where I read that. All I can say is that I don't have any problems with any of our SQL Servers when I use "mm/dd/yyyy" or add the time to it.
