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 > -----Original Message----- > From: Paulo Roberto Kappke [SMTP:paulok@cyclades.com.br] > Sent: Wednesday, September 22, 1999 12:48 PM > To: Jackson, DeJuan > Cc: pgsql-sql@postgreSQL.org > Subject: Re: [SQL] Date type select > > OK DeJuan, but, probably your field's type is datetime and my type is > date.
