本机sql到Doctrine_RawSql

Question

我有这个SQL查询。

SELECT
    c.id, 
    c.name,
    c.slug,
    sc.id,
    sc.name,
    sc.slug,
    COUNT(bsc.id) AS business_count
FROM
    fi_category c
LEFT JOIN
    fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN (
        fi_business b
    INNER JOIN
        fi_business_subcategory bsc ON b.id = bsc.business_id AND (bsc.deleted_at IS NULL)
    INNER JOIN
        fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1
    ) ON sc.id = bsc.subcategory_id
WHERE 
    (c.deleted_at IS NULL) 
GROUP BY 
    c.id, sc.id

因为DQL不支持此类查询。我想将它与Doctrine_RawSql

一起使用

我尝试过这样使用它。

$q = new Doctrine_RawSql();
$q->select('{c.name}, {c.slug}, {sc.name}, {sc.slug}, {COUNT(bsc.id) AS business_count}');
$q->from('fi_category c LEFT JOIN fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL) LEFT JOIN (fi_business b INNER JOIN fi_business_subcategory bsc ON b.id = bsc.business_id AND (bsc.deleted_at IS NULL) INNER JOIN fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1) ON sc.id = bsc.subcategory_id');
$q->groupBy('GROUP BY c.id, sc.id');
$q->addComponent('c', 'Model_Category c');
$q->addComponent('sc', 'c.Subcategory sc');
$q->addComponent('bsc', 'sc.BusinessSubcategory bsc');
$q->addComponent('b', 'bsc.Business b');
$q->addComponent('su', 'b.Suburb su');
$q->execute();

此查询无效，这是为上述SQL查询构建Doctrine_Rawsql的正确方法吗？

更新：这是此问题的延续，select query and count based on condition如果有人可以通过使用@MvG提供的解决方案中的任何查询帮助我构建Doctrine_Rawsql
