normaly i wouldn't be this picky but...... language-lawyer version.. you used the wrong version of the lang, the docs say it complies to SQL3, which has completely different wording than SQL99 -----Original Message----- From: Peter Eisentraut [mailto:peter_e@gmx.net] Sent: Thursday, June 22, 2000 11:17 AM To: Marc Britten Cc: pgsql-general@postgresql.org Subject: Re: [GENERAL] boolean isn't boolean? Marc Britten writes: > why does a boolean value return a t or an f? The language-lawyer version: ISO/IEC 9075-5:1999 ("SQL99") 17.2 GR6 "If [the result of the query expression] is not empty, then [it] is returned. The method of returning [it] is implementation-defined." Then that's how this implementation defines it. :-)
