Hi! Bruce,
Many thanks to your great contributions to Pgsql
projects.
I cannot find the following to-fix bug in section
"SERVER-SIDE LANGUAGES" in "PostgreSQL TO-DO List".
Please also refer to:
"Example 23-4. A PL/pgSQL Function on Composite Type"
in integrated on-line document.
Best Regards,
CN
=========================
create table test(f1 integer,f2 integer);
CREATE FUNCTION fun1(test) RETURNS BOOLEAN AS '
DECLARE
f1 FOR $1.f1;
f2 FOR $1.f2;
integer sum;
BEGIN
sum:=f1+f2;
raise notice ''f1+f2'',sum;
RETURN TRUE;
END;' LANGUAGE 'plpgsql';
-----------------------
CREATE FUNCTION fun2() RETURNS OPAQUE AS '
BEGIN
PERFORM fun1(NEW);
RETURN NEW;
END;' LANGUAGE 'plpgsql';
CREATE TRIGGER ttest AFTER INSERT ON test FOR EACH
ROW EXECUTE PROCEDURE fun2();
insert into test values(1,2);
NOTICE: Error occurred while executing PL/pgSQL
function fun2
NOTICE: line 2 at assignment
ERROR: NEW used in non-rule query
