Question

I have two tables:

table Filters

id   INT(11) PRIMARY KEY
text VARCHAR(50)

table items

id    INT(11) PRIMARY KEY
title VARCHAR(255)

I’d like to dipslay all filter terms along with count fo their occurence among titles

I’m currently using this statement but I get zeroes as counts

SELECT  filters.text, 
        (SELECT COUNT(items.id) 
         FROM items 
         WHERE (items.title LIKE 'filters.text' OR 
                items.title LIKE '%filters.text' OR 
                items.title LIKE '%filters.text%' OR 
                items.title LIKE 'filters.text%')
        ) AS count
        FROM filters, items
GROUP BY filters.ID
ORDER BY filters.ID DESC

Answer 1

give this a try,

SELECT  a.text, COUNT(b.id) totalCount
FROM    filters a
        LEFT JOIN items b
            ON b.title LIKE CONCAT('%',a.text,'%')
GROUP BY a.text
ORDER BY totalCount DESC
