As an example:
CREATE TABLE userdata ( userdata_id serial NOT NULL, user_id smallint, data text
);
CREATE TABLE users ( user_id serial NOT NULL, name text, "type" smallint
);
INSERT INTO userdata (userdata_id, user_id, data) VALUES (1, 1,
'2005-01-01');
INSERT INTO userdata (userdata_id, user_id, data) VALUES (2, 2,
'2005-10-10');
INSERT INTO userdata (userdata_id, user_id, data) VALUES (3, 3,
'052-44-5863');
INSERT INTO userdata (userdata_id, user_id, data) VALUES (4, 4,
'052-44-5863');
INSERT INTO users (user_id, name, "type") VALUES (1, 'Jim', 1);
INSERT INTO users (user_id, name, "type") VALUES (2, 'John', 1);
INSERT INTO users (user_id, name, "type") VALUES (3, 'Bob', 2);
INSERT INTO users (user_id, name, "type") VALUES (4, 'Bill', 2);
Then run the query:
SELECT *
FROM
(SELECT u.user_id, ud.dataFROM users u, userdata udWHERE u.user_id = ud.user_idAND u.type = 1
) subusers
WHERE subusers.data::text::date < now();
Returns the message: ERROR: date/time field value out of range:
"052-44-5863"
So my question is how does this query ever even SEE the row containing
"052-44-5863"? The sub-query doesn't return that row so I don't see
how it can get this error.
