[DC-914] Doctrine_Pager ignores custom COUNT query

Mon, 7 Nov 2011 22:54:46 +0000

I found some problem when I tried to define custom query for results counting. Defined custom COUNT query is totally ignored and executed default one. I will give you full description of problem bellow.

We have following source code:

 
$q_select = Doctrine_Query::create ()
->select ( 'DISTINCT p.product_name AS product_name' )
->from ( 'Product p' )
->where( 'p.product_name LIKE ?', '%motorola%');
				
$q_count = Doctrine_Query::create ()
->select ( 'COUNT (DISTINCT p.product_name) num_results' )
->from ( 'Product p' )
->where( 'p.product_name LIKE ?', '%motorola%');
												
$pager = new Doctrine_Pager( $q_select, 1, 25 );										
$pager->setCountQuery($q_count);

Let's check custom query before calling $pager->execute() method:

 
echo $pager->getCountQuery();

Output:

 
SELECT COUNT (DISTINCT p.product_name) num_results FROM Product p WHERE p.product_name LIKE ?

Looks like until now is everything is correct. Let's call $pager->execute() method:

 
$products = $pager->execute();

Let's check executed queries using Symfony SQL queries log panel:

SELECT COUNT(*) AS num_results FROM product p WHERE p.product_name LIKE '%motorola%'
7.27s, "doctrine" connection

SELECT DISTINCT p.product_name AS p__0 FROM product p WHERE (p.product_name LIKE '%motorola%') LIMIT 25
3.25s, "doctrine" connection

Executed COUNT query is not same we set using $pager->setCountQuery($q_count). Our defined custom COUNT query is totally ignored and executed default one:

INSTEAD OF THIS CUSTOM COUNT QUERY:

SELECT COUNT (DISTINCT p.product_name) num_results FROM Product p WHERE p.product_name LIKE '%motorola%'

EXECUTED DEFAULT COUNT QUERY:

SELECT COUNT(*) AS num_results FROM product p WHERE p.product_name LIKE '%motorola%'
