a real example: (table harz_ufpos references harz_uf) create or replace function gh_insert(text,int,int,text,int,float) returns int as $$ declare c int; begin select into c count(*) from harz_uf where (uf,ab) = ($1,$2); if c = 0 then insert into harz_uf (uf,ab,beschreibung,aktiv) values ($1,$2,$4,'t'); end if; insert into harz_ufpos (uf,pos,anzahl,rest,flaeche) values ($1,$3,$5,$5,$6); return 1; end; $$ language 'plpgsql'; HTH, Andreas -- Really, I'm not out to destroy Microsoft.
