Re: SQL problem with date types

Hi Bob,

I think your problem lies in the fact that date columns also contain a time element..in the first select you allow for 'greater than or equal to' so anything later (greater than) DEC 06 at midnight gets returned..in the second select you're specifying rows that must exactly equal both the date and time (to the nano second) the equal sign is the problem..or, truncate the date column so it just returns dates with no times.

Hope this helps,

Steve
