在SQL过程中的情况

Question

I'm trying to use a case when in a sql procedure.

What i want is that when the variable @ID_ETAPA is 6 the where is a little diferent. But i'm getting multiple erros. Incorrect syntax near = And Incorrect syntax near ELSE Someone knows what i'm missing?

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

---

THE full select with error in the where clause.

SELECT DISTINCT CF.NOM_FILIAL,
        SS.COD_SOLICITACAO,

ORDER BY SS.COD_SOLICITACAO

Answer 1

The CASE statement must be part of the WHERE statement. Try:

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

See this post for more information: "CASE" statement within "WHERE" clause in SQL Server 2008

EDIT

Try taking SS.ID_STATUSSOLICITACAO = 1 out of the CASE expression and placing it afterwards:

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
