爲什麼我得到這個錯誤：

The multi-part identifier could not be bound on line 18
The multi-part identifier "ShipTB.sh_Type" could not be bound.
Line 32 the multi-part identifier "ShipTB.sh_Type" could not be bound.

你不能做到這一點，這條路。 IF語句中的ShipTB.sh_Type是一個結果集，它是一個包含多個值的字段。此外，它不能參考SELECT條款之外。如果該字段ShipTB.sh_Type應該只包含一個值，那麼您可以將其選擇爲標量變量，如@type，然後將其置於該條件中。

否則，如果該字段ShipTB.sh_Type包含更多的價值，那麼我認爲你正在嘗試做一個有條件的加入，在這種情況下，你可以這樣做，在一個查詢，像這樣：

... 

SELECT  
    ExceptionTB.excep_ref, 
    ExceptionTB.emo_no, 
    ExceptionTB.broker, 
    ExceptionTB.r_date, 
    ShipTB.S_Name, 
    ShipTB.sh_Type, 
    ArrivalNotiDate.Arri_noti_date, 
    ArrivalNotiDate.port, 
    PassengerCertificate.[1], 
    PassengerCertificate.[2], 
    PassengerCertificate.[3], 
    PassengerCertificate.[4], 
    PassengerCertificate.[5], 
    PassengerCertificate.[6] 
    CargoCertificate.[1], 
    CargoCertificate.[2], 
    CargoCertificate.[3], 
    CargoCertificate.[4], 
    CargoCertificate.[5], 
    CargoCertificate.[6], 
    CargoCertificate.[7], 
    CargoCertificate.[8] 
FROM  ExceptionTB 
INNER JOIN ShipTB     
     ON ExceptionTB.emo_no = ShipTB.Emo_No 
INNER JOIN ArrivalNotiDate  
     ON ExceptionTB.excep_ref = ArrivalNotiDate.exp_ref 
INNER JOIN CargoCertificate  
     ON ExceptionTB.excep_ref = CargoCertificate.excep_ref 
     AND ShipTB.sh_Type  = 'تجارية' 
INNER JOIN PassengerCertificate 
     ON ExceptionTB.excep_ref = PassengerCertificate.excep_ref 
     AND ShipTB.sh_Type  = 'سياحية' 
WHERE  ExceptionTB.excep_ref LIKE CAST(@keyser as varchar(50)) + '%';
