Doctrine 2 DQL CASE WHEN in Count

Question

I have this Query in native MySQL Code

SELECT *
FROM `turn`
LEFT JOIN (
    poi
) ON ( turn.id = poi.turn_id )
GROUP BY turn.id
ORDER BY count( case when poi.image = 1 then 1 else null end) DESC;

I need to rebuild this in Doctrine 2 DQL

My attempt so far is this:

SELECT t, COUNT((CASE WHEN Bundle\Entity\Poi p.image = 1 then 1 ELSE NULL END)) AS num
FROM Bundle\Entity\Turn t
JOIN t.pois p
GROUP BY t.id
ORDER BY num DESC

And im getting this error:

An exception has been thrown during the rendering of a template ("[Syntax Error] line 0, col 99: Error: Expected end of string, got '.'") in Bundle:Admin:showTurnsFiltered.html.twig at line 75.

What am i doing wrong?

Answer 1

I found it by myself after hours of trying and searching, it's working with this DQL:

$dql = 'SELECT t, SUM(CASE WHEN p.image = 1 THEN 1 ELSE 0 END) AS numImage
                    FROM Bundle\Entity\Turn t
                    JOIN t.pois p
                    GROUP BY t.id
                    ORDER BY numImage DESC;  

Important that you need to use SUM instead of COUNT
