案例在SQL過程

Question

時我試圖在sql過程中使用一個案例。

我想要的是當變量@ID_ETAPA是6時，哪裏有點不同。但我收到了多個錯誤。 不正確的語法附近= 和 ELSE附近的語法不正確 有人知道我錯過了什麼嗎？

WHERE CASE 
     WHEN @ID_ETAPA=6 THEN 
     SS.ID_STATUSSOLICITACAO = 1 -- PENDENTES 
      AND SS.Id_etapa = @ID_ETAPA 
     Else 
      SS.ID_STATUSSOLICITACAO = 1 -- PENDENTES 
    END 

---

完整的選擇，錯誤的where子句。

ORDER BY SS.COD_SOLICITACAO 

Answer 1

CASE聲明必須是WHERE聲明的一部分。嘗試：

WHERE SS.ID_STATUSSOLICITACAO = CASE 
     WHEN @ID_ETAPA=6 THEN 
     SS.ID_STATUSSOLICITACAO = 1 -- PENDENTES 
      AND SS.Id_etapa = @ID_ETAPA 
     Else 
      SS.ID_STATUSSOLICITACAO = 1 -- PENDENTES 
    END 

看到這個職位的詳細信息："CASE" statement within "WHERE" clause in SQL Server 2008

編輯

嘗試採取SS.ID_STATUSSOLICITACAO = 1出CASE表達的，並把它算賬：

WHERE SS.Id_etapa = 
    CASE WHEN @ID_ETAPA=6 THEN @ID_ETAPA 
     ELSE 0 --- What you use for this value depends on what other values are possible for the @ID_ETAPA variable of course 
    END 
AND SS.ID_STATUSSOLICITACAO = 1
