CREATE OR REPLACE FUNCTION public.sample(varchar)
RETURNS SETOF record AS
'
DECLARE
row RECORD;
BEGIN
LOCK TABLE table1 IN ROW SHARE MODE;
FOR urlrow in EXECUTE \'SELECT * FROM "table1"\'
LOOP
UPDATE "table1" SET col1=5 WHERE "col2"=6
RETURN NEXT row;
END LOOP;
RETURN;
END;
'
LANGUAGE 'plpgsql' VOLATILE;
