如何使用typeorm createQueryBuilder编写此查询？

Question

我想使用typeorm createQueryBuilder编写这个原始查询。我怎样才能使用typeorm createQueryBuilder来实现这个目标？

SELECT *
FROM Location l
INNER JOIN LocationType t ON l.TypeId = t.Id
LEFT JOIN Location p ON l.ParentId = p.Id
LEFT JOIN (SELECT locationId, SUM(Units) TotalUnits FROM ItemInventory GROUP BY LocationId) qty ON l.Id = qty.LocationId`
