我有三个表与另一个表共享一个字段，所以：
Employee_Data: EMP_ID, PHONE_EXTENSION
Outage_Data: DATE, EMP_ID
Phone_Data: DATE, PHONE_EXTENSION
我需要将代理数据与其他两个表中的数据匹配的数据组合在一起。基本上，我需要将来自Outage_data和Phone_data的数据（因为它全部按日期分组）与Employee_Data作为“桥梁”进行组合。
我已经拥有了我的SELECT，并且所有内容都像它需要的那样布局;我只需要帮助加入。
修改的 按请求，这是完整查询。为了简单起见，我尽量不这样做：

ORDER By P.DATE
