I have table:
--------------------------------------------
CREATE TABLE "public"."test" (
"id" INTEGER,
"text1" VARCHAR(25),
"text2" VARCHAR(25)
) WITH OIDS;
INSERT INTO test VALUES (1, 'qwerty', '111');
INSERT INTO test VALUES (2, 'asdfgh', '222');
--------------------------------------------
and function:
--------------------------------------------
CREATE OR REPLACE FUNCTION "public"."test1" () RETURNS integer AS
$body$
BEGIN
UPDATE test SET text1='qqq' WHERE id = 2;
RETURN 2;
END;
$body$
LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
--------------------------------------------
When I do
SELECT test1();
it works fine and return "2".
But this thing don't work:
UPDATE test SET text2='test' WHERE id = (SELECT test1());
(rows affected: 0)
Why? There is two updates on the same row, but work only first update
(in the function). Maybe it's bug?
P.S.:
I'm using PostgreSQL 8.0.1 on Win32.
Sorry for my english.
