Subject: problems with array
Date: Sat, 15 Oct 2005 08:49:15 +0000
Message-ID: <BAY108-F2573522163DF0C1FC43D0DD27C0@phx.gbl> (raw)
PostgreSQL is 7.4.7.
My first table
CREATE TABLE tb_cat (
id INTEGER,
desc text
);
INSERT INTO tb_cat VALUES (10, 'cat10');
INSERT INTO tb_cat VALUES (20, 'cat20');
INSERT INTO tb_cat VALUES (30, 'cat30');
My second table
CREATE TABLE tb_array(
id INTEGER,
cat INTEGER[]
);
INSERT INTO tb_array VALUES(1, ARRAY [10, 20]);
When I write my select
SELECT * from tb_cat WHERE id IN (SELECT cat FROM tb_array WHERE id=1);
the output is:
ERROR: operator does not exist: integer = integer[]
HINT: No operator matches the given name and argument type(s). You may need
to add explicit type casts.
Can anyone help me?
thanks.
