我在员工和工作组之间有以下多对多关系:
employees table ----------------- id empgroups table --------------- employee_id workgroup_id workorders table ---------------- workgroup_id
我正在尝试编写SQL,它将根据员工所属的工作组列出员工的所有工作人员.
这是我的尝试:
SELECT wonum, workgroup_id
FROM workorders
INNER JOIN employees
ON workorders.employee_id = employee_id
INNER JOIN empgroups
ON employees.employee.id = empgroups.employee_id
WHERE employee_id = 2
我得到的错误是:
ERROR: schema "employees" does not exist
对不起 - 员工的身份不是employee.id
