PostgreSQL version: 8.1.1-1
Operating system: Windows
Description: Error "relation with OID ... does not exist" when using
temporary table in function.
Details:
After running function proc_3 (described below) more than once error
"relation with OID ... does not exist" occures.
First run of function proc_3() is OK but the second run always fails until
we recreate function proc_2().
Script to reproduce.
--------------------------------------------------------
--DROP FUNCTION proc_1();
CREATE OR REPLACE FUNCTION proc_1() RETURNS int AS
$BODY$
DECLARE
__nCount int;
BEGIN
SELECT INTO __nCount COUNT(*) FROM __tmp_xx;
return __nCount;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
--DROP FUNCTION proc_2();
CREATE OR REPLACE FUNCTION proc_2() RETURNS int AS
$BODY$
DECLARE
__nCount int;
BEGIN
CREATE TEMPORARY TABLE __tmp_xx(
nId int PRIMARY KEY,
wstrName varchar(256) NOT NULL
);
INSERT INTO __tmp_xx (nId, wstrName) VALUES (1, 'xx');
__nCount := proc_1();
DROP TABLE __tmp_xx;
return __nCount;
END
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
--DROP FUNCTION proc_3();
CREATE OR REPLACE FUNCTION proc_3() RETURNS int AS
$BODY$
DECLARE
__nCount int;
BEGIN
__nCount = proc_2();
--DELETE FROM t_res;
--INSERT INTO t_res(nId, nValue) VALUES(1, __nCount);
return __nCount;
END
