Thanks for the reply!
Alright, I'll use EXISTS instead of IN .... I didn't know that EXISTS is
faster.....

About my query, I have tried :

"
SELECT * FROM entry where isapproved='y' AND EXISTS (SELECT id
FROM subcategory WHERE catid='2') ORDER BY subcatid DESC LIMIT 5;
";
This will return only 5 rows....

But when I add the GROUP BY, then I got error
"
SELECT * FROM entry where isapproved='y' AND EXISTS (SELECT id
FROM subcategory WHERE catid='2') ORDER BY subcatid DESC LIMIT 5 GROUP BY
subcatid;
"

: ERROR: parser: parse error at or near "GROUP"

Thanks.....
