Probably I didn't make myself clear enough. :) I know this works (see
above two examples).
I need to connect two tables, one is:
CREATE TEMP TABLE haystack (straw text);
INSERT INTO haystack SELECT n FROM generate_series(1,100) AS x(n);
CREATE TEMP TABLE needles (id int, straws text[]);
INSERT INTO needles VALUES (1, '{10,15,aaa}');
SELECT * FROM haystack WHERE straw = ANY (SELECT straws FROM needles
WHERE id=1);
ERROR: operator does not exist: text = text[]
HINT: No operator matches the given name and argument type(s). You
might need to add explicit type casts.
But you are right, though! I just need to leave off the subselect! Thanks!
SELECT h.* FROM haystack h JOIN needles ON straw = ANY (straws);
(not exactly what I was looking for, but it works ;))
