Question

I am doing a pretty normal routine, but having a tough time getting my output correct.

I have two tables: *ads_list* (listings) and *ads_cate* (categories).

I am currently displaying my category list like so:

SELECT id, cateName FROM ads_cate ORDER BY cateName

What I am trying to achieve: count of all items in each category in this format:

Category | Number of Ads

categoryName 56

This is my current code, and have been tweaking but getting no output in my array:

SELECT 

ads_cate.id, 
ads_cate.cateName, // Category Name

ads_list.id, 
ads_list.COUNT(title), // Title of ad
ads_list.Category // Relational Category ID INT(11)

FROM

ads_cate, 
ads_list

GROUP BY cateName 
ORDER BY cateName

I am calling in all required fields and running a COUNT() on my title field (as these are unique for each ad) and then I am grouping by cateName which also seems correct.

Answer 1

See what this gives you. I think it is what you need.

SELECT 
ads_cate.cateName, // Category Name
COUNT(ads_list.id), // Title of ad
FROM

ads_cate
INNER JOIN 
ads_list
ON ads_cate.id = ads_list.category

GROUP BY cateName 
ORDER BY cateName
