链接查询错误代码1052

我收到错误代码1052列FireStationHome在字段列表是试图在查询链接查询错误代码1052

以等值连接两个表一起这是我使用下面的代码含糊：

SELECT FiremanID, FiremanHomeStation,StationPhone 
FROM FIRE_REPORT AS F, FIRE_STATION AS FS 
WHERE F.FiremanHomeStation = FS.FiremanHomeStation 
AND StationPhone ='703';

通过论坛阅读，我了解到我需要通过链接键链接第一个关系。 FiremanHomeStation是我需要运行以下指令的唯一连接键。

显示以'703'开头的所有消防队员的消防员，消防员主机和电话号码。

使用博伊斯科德方法我已恢复正常以下

FIRE_REPORT(FireID,Alarms,Address,FiremanID,FiremanName,FiremanPhone,FiremanHomeStation,StationAddress,StationPhone,TruckID,LicensePlate)

规则：

每个火可以有分配给它
几个消防队员每个消防可以分配几个消防车到它
每个消防员可以被分配到几个火灾
每辆消防车和被分配到 sev全部擦除触发
每个消防员具有单个家庭站
每个站是唯一
每个站具有单个电话号码

主键

FireID, FiremanID, FiremanHomeStation,TruckID 

FireID -> Alarms, Address 
FiremanID -> FiremanName, FiremanPhone, FiremanHomeStation 
FiremanHomeStation -> StationAddress, StationPhone 
TruckID -> LicensePlate

FIRE_REPORT（FireID，FiremanID，FiremanHomeStation， TruckID）
FIRE（FireID，报警，地址）
FIREMAN_ID（FiremanID，FiremanName，FiremanPhone）
FIRE_STATION（FiremanHomeStation，StationAddress，StationPhone）
卡车（TruckID，LicensePlate）

参照完整性约束
FireID在FIRE_REPORT必须存在于FireID在FIRE
FiremanID在FIRE_REPORT必须存在于FiremanID在FIREMAN_ID
FiremanHomeStation在FIRE_REPORT必须FiremanHomeStation存在于在FIRE_REPORT FIRE_STATION
TruckID必须TruckID存在于卡车

FiremanHomeStation在这两个表中都存在，但您不指定要从哪个表中指定结果，这是不明确的。

SELECT FiremanID, FS.FiremanHomeStation,StationPhone 
FROM FIRE_REPORT AS F, FIRE_STATION AS FS 
WHERE F.FiremanHomeStation = FS.FiremanHomeStation 
AND StationPhone ='703';

应工作
