php - Doctrine Multiple Join Query 给出错误

Question

我在 Doctrine 2.3.3 中编写一个查询，我想从 4 个不同的表中检索数据。现在我编写了一个适用于单连接的查询。但是当我编写多个连接查询时，它会显示一个错误..

我的查询是

$query = $parent->entityManager->createQuery('SELECT t,s,q,d FROM TblEmployee t JOIN TblEmployeeShifts s JOIN TblEmployeeQualification q JOIN TblEmployeeDepartment d where t.employeeId = s.employeeId and t.employeeId = d.employeeId and t.employeeId = q.employeeId and t.employeeId ='.$data);

但上面的查询给了我一个错误，如下所示，

[Syntax Error] line 0, col 89: Error: Expected =, <, <=, <>, >, >=, !=, got 'q'

请指导我在哪里我错了..

这是我们可以在 Doctrine 中执行多重连接的方法之一

$query = $parent->entityManager->createQuery('
    SELECT t,s,d,q 
    FROM TblEmployee t
    JOIN TblEmployeeDepartment s WITH t.employeeId = s.employeeId
    JOIN TblEmployeeShifts d WITH t.employeeId = d.employeeId
    JOIN TblEmployeeQualification q WITH t.employeeId = q.employeeId 
         and t.employeeId = '.$data
);
