 Description   

For example:

$queryBuilder
    ->select('DISTINCT c.id')
    ->from('Campaigns', 'c')
    ->leftJoin('c', 'CampaignOperations', 'od', 'od.campaignId = c.id AND od.operation = :operation')
    ->from('BannerGroups', 'bg')
    ->innerJoin('bg', 'BannerGroupStrategies', 'bgs', 'bgs.groupId = bg.id AND bgs.advSystem = :system')
    ->where('bg.campaignId = c.id');

Builded the query:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation)
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system), 
  BannerGroups bg
  WHERE (bg.campaignId = c.id)

If this query execute on mysql, we get error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'bg.id' in 'on clause'

Expected result:

SELECT DISTINCT c.id FROM Campaigns s 
  LEFT JOIN CampaignOperations od ON (od.campaignId = c.id AND od.operation = :operation),
  BannerGroups bg
  INNER JOIN BannerGroupStrategies bgs ON (bgs.groupId = bg.id AND bgs.advSystem = :system)
  WHERE (bg.campaignId = c.id)
