Обсуждение: Stupid Monday Problem
Ok- here's the problem ( too little coffee?)... This query runs under Access. I of course change a bit of the SQL ( removed the '#' and have played with quotes), but can'tseem to get it to run. What the #%$^& am I doing wrong here? Kenn SELECT oid FROM file_header WHERE expire_date < 04/16/00 ADODB.Recordset.1 error '80004005' Error while executing the query; ERROR: Unable to identify an operator '<' for types 'date' and 'int4' You will have to retypethis query using an explicit cast
Hi. Dates should be quoted like '04/16/00' What you're trying to do is to calculate an integer of value 04/16/00 (which, if the parser would let it through, would even generate a division by zero error.)

try (add '' around date literal): SELECT oid FROM file_header WHERE expire_date < '04/16/00' On Mon, 17 Apr 2000, Kenn Thompson wrote: > Ok- here's the problem ( too little coffee?)... > > This query runs under Access.

You have to cast the date properly - postgres is interpreting this as 4 divided by 16 divided by 0. Try: SELECT oid FROM file_header WHERE expire_date < '04/16/00'::date; --------------------------------------------------------------------- Andrew J.
