Question

I’m doing a simple MySQL query to count the number of rows a query is returning without the effect of the LIMIT clause. I’m using Active Records with Codeigniter PHP framework.

Problem: I’m getting an error when SQL_CALC_FOUND_ROWS is used. Why is this so?

Query

SELECT `listing_id`, SQL_CALC_FOUND_ROWS listing_id FROM (`listings`) LIMIT 100

Error

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘SQL_CALC_FOUND_ROWS listing_id FROM (listings) LIMIT 100′ at
line 1

Codeigniter Active Records

$this->db->select('listing_id')
            ->select('SQL_CALC_FOUND_ROWS listing_id', FALSE)
            ->from('listings')
            ->where('price < 1000')
            ->limit($limit, $offset)
            ->order_by('listing_id', 'desc');

Answer 1

You can use MySql’s count() function to achieve what you are looking for ie.

SELECT `listing_id`, count(*) FROM (`listings`) LIMIT 100
