Hello,
Im having problems trying to concatenate two arrays in a plpgsql
function. Doing the following :
--
CREATE TABLE t1 (
id1 int,
id2 int
);
INSERT INTO t1 (id1, id2) VALUES (1,3);
INSERT INTO t1 (id1, id2) VALUES (1,4);
INSERT INTO t1 (id1, id2) VALUES (1,5);
INSERT INTO t1 (id1, id2) VALUES (1,6);
INSERT INTO t1 (id1, id2) VALUES (2,7);
INSERT INTO t1 (id1, id2) VALUES (2,8);
CREATE OR REPLACE FUNCTION tmpfunc(int[]) RETURNS int[] AS '
DECLARE
Ids ALIAS FOR $1;
AllIds int[];
BEGIN
AllIds := Ids || array(select id2 from t1 where id1 in (Ids) group by id2);
RETURN AllIds;
END
' LANGUAGE 'plpgsql';
SELECT * FROM tmpfunc(array[1,2]);
ERROR: operator does not exist: integer = integer[]
--
What am I doing wrong here?
Thank you in advance,
- A Gilmore
