MySql: Problem when using a temporary table
- by Alex
Hi, I'm trying to use a temporary tables to store some values I need for a query. The reason of using a temporary table is that I don't want to store the data permanently so different users can modify it at the same time. That data is just stored for a second, so I think a temporary table is the best approach for this.
The thing is that it seems that the way I'm trying to use it is not right (the query works if I use a permanent one).
This is an example of query:
CREATE TEMPORARY TABLE SearchMatches (PatternID int not null primary key, Matches int not null)
INSERT INTO SearchMatches (PatternID, Matches)
VALUES ('12605','1'),('12503','1'),('12587','2'),('12456','1'),
('12457','2'),('12486','2'),('12704','1'),(' 12686','1'),
('12531','2'),('12549','1'),('12604','1'),('12504','1'),
('12586','1'),('12548','1'),('12 530','1'),('12687','2'),
('12485','1'),('12705','1')
SELECT pat.id, signatures.signature, products.product, versions.version, builds.build, pat.log_file, sig_types.sig_type, pat.notes, pat.kb
FROM patterns AS pat
INNER JOIN signatures ON pat.signature = signatures.id
INNER JOIN products ON pat.product = products.id
INNER JOIN versions ON pat.version = versions.id
INNER JOIN builds ON pat.build = builds.id
INNER JOIN sig_types ON pat.sig_type = sig_types.id, SearchMatches AS sm
INNER JOIN patterns ON patterns.id = sm.PatternID
WHERE sm.Matches <> 0
ORDER BY sm.Matches DESC, products.product, versions.version, builds.build
LIMIT 0 , 50
Any suggestion?
Thanks.
