Count number of articles in categories

This code only shows categories with articles in them. I want to show all categories. Pls help.

$query = "SELECT C.id, C.jcat_name,COUNT(A.catid) AS catid FROM jt_categories C INNER J开发者_Python百科OIN jt_articles A ON C.id = A.catid GROUP BY C.id";

change to left join

 SELECT C.id, C.jcat_name,COUNT(A.catid) AS catid FROM jt_categories C 
LEFT JOIN jt_articles A ON C.id = A.catid GROUP BY C.id

Change INNER JOIN for LEFT JOIN in your query.

INNER JOIN looks explicitely for the join in the data

replace the inner join by a left outer join

Change INNER JOIN to LEFT JOIN.

Did u try LEFT JOIN ? bc. (i think) in second table u have NULL articles for some categories.
