在下面的代码中，当employee_code_list 超过2000 项时抛出错误，如下所述。但是，当列表少于 2000 项时，它可以完美运行。
query = session.query(TblUserEmployee, TblUser).filter(
and_(
(TblUser.UserId == TblUserEmployee.EmployeeId),
(func.lower(TblUserEmployee.EmployeeCode).in_(employee_code_list)),
(TblUser.OrgnId == MIG_CONSTANTS.context.organizationid),
(TblUser.UserTypeId == user_type)
))
results = query.all()
这是引发的错误的相关部分：
