Question

I want to select rows with using inner join to another table.

SELECT COUNT(t3.ID), t3.act, t3.dj_id, t1.ID, 
  t1.name, t1.label_id, t1.date, t1.genre, 
  t1.plink, t1.featana, t1.promo_aktif 
FROM `release` t1 
INNER JOIN `acts` t3 ON t3.release_id = t1.ID 
WHERE t1.ID IN ($lst) AND t1.promo_aktif = 'Active' 
 AND t3.act = 'hide' AND t3.dj_id = '$id' 
HAVING COUNT(t3.ID) = 0 
ORDER BY t1.ID DESC 
LIMIT 0,15

In this query, result is empty. it selects 0 rows. but i am sure there are rows with this conditions.

query needs to select rows in t1 when there is no record found in t3

where am i wrong in this query ?

thanks

EDIT

correct code is

SELECT t3.act, t3.dj_id, t1.ID, 
  t1.name, t1.label_id, t1.date, t1.genre, 
  t1.plink, t1.featana, t1.promo_aktif 
FROM `release` t1 
LEFT JOIN `acts` t3 ON t3.release_id = t1.ID AND t3.act = 'hide' AND t3.dj_id = '$id' 
WHERE t1.ID IN ($lst) AND t1.promo_aktif = 'Active'
AND t3.release_id is null
ORDER BY t1.ID DESC 
LIMIT 0,15
