I think, you should prevent NULL-strings. To ensure that you can use coalesce. For instance: sql:='SELECT FROM foo WHERE col = ' || coalesce(var, default-value) Other way: you check if your sql-string is NULL or not Andreas -- Andreas Kretschmer Kontakt: Heynitz: 035242/47150, D1: 0160/7141639 (mehr: -> Header) GnuPG-ID: 0x3FFF606C, privat 0x7F4584DA http://wwwkeys.de.pgp.net -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
