hi , what is wrong with this if statement in this function if distance ='' THEN distance := 1; end if; here distance variable is of type integer , this function has been created successfully but when i execute this function it gives me this error , ERROR: invalid input syntax for integer: "" LINE 1: SELECT distance ='' ^ QUERY: SELECT distance ='' CONTEXT: PL/pgSQL function "getsitesbytfid" line 6 at IF ********** Error ********** ERROR: invalid input syntax for integer: "" SQL state: 22P02 Context: PL/pgSQL function "getsitesbytfid" line 6 at IF ======================================================================== The empty-string is not a valid syntax for an integer. You probably want: IF (distance IS NULL) . David J. -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
