RE: [SQL] Date type select

From
"Jackson, DeJuan"
Date:
I think you misunderstood, try:
SELECT * FROM callsWHERE date_trunc('month', date_in)='9/1/1999'ORDER BY employee_nbr, date_in;

'date_trunc' is the function not my field name.  Your method works well for
date but might not for daytime's because of the hour:minutes:seconds
specification, but that's another discussion.DEJ

Yes, I made a big confusion.

The statement that you sent and George worked fine too.
