Question

表1：Userinfo_attarea

    employee_id area_id
          13    61
          14    61

表2：Userinfo

userid  badgenumber
   14   ST021
   15   ST013

表3：DevicePersonnelarea

areaid  areaname
  18    PROJECT119
  15    PROJECT108

表4：employee_attarea

emp_code    area_id
  ST021     119
  ST013     108

我正在使用以下触发器它工作正常但是当我更新多个时它只更改为单个值..如果值已经存在意味着它将更新，否则为同一employee_id插入多个。 mY tRIGGER查询：

            VALUES (@employee_code,@areaid);
        END
    END
END

预期输出：userinfo_attarea

employee_id area_id
  14           1
  14           2
  14          18

任何人都有帮助...
