Question

I have googled my problem but didnt get the answer.
I want to list all of the results of below sql including NULL (when COUNT(review.id) return 0 also) but instead i just got the results of articles of place that only contains review.

$sql = "SELECT tbl_place.id, tbl_place.region_id, tbl_place.subregion_id, tbl_place.title, tbl_place.metalink, tbl_place.img_thumbnail, tbl_place.summary, tbl_place.category1_id, tbl_place.category2_id, tbl_place.category3_id, COUNT(review.id) AS total_review FROM tbl_place
        JOIN review ON tbl_place.id = review.place_id
        WHERE
        tbl_place.category1_id = '32'   AND 
        tbl_place.status = '1'          AND
        review.rating != '0.00'         
        GROUP BY tbl_place.id
        ORDER BY total_review $by
        LIMIT $limit OFFSET $offset";

Answer 1

please use left join for review table instead of join. join is by default inner join so it will take only matched records.
