Another option: rewrite your function: CREATE OR REPLACE FUNCTION "name_add" (p_name varchar, p_created_date date) RETURNS integer AS $$ BEGIN case when $2 is null then INSERT INTO names(name, created_date) values (p_name, default); else insert into names values ($1, $2); end case; return 1; end; $$ language plpgsql; Andreas -- Andreas Kretschmer Kontakt: Heynitz: 035242/47150, D1: 0160/7141639 (mehr: -> Header)
