多个表达式在sql查询中使用case exprssion

Question

我有下面写的查询。

SELECT T1.[AcctCode],T1.[Segment_0],SUM(T0.[DebLTotal]) AS BUDGET, SUM(T3.[Debit]) AS DEBIT, 
     AcctName = CASE WHEN T1.[Segment_0] LIKE '6001%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6002%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6003%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6004%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6005%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6006%%' THEN 'Operating Cost' 
     ELSE T1.[AcctName] END 
FROM OBGT T0 INNER JOIN OACT T1 ON T0.[AcctCode]=T1.[AcctCode] INNER JOIN OBGS T2 
ON T0.[Instance] = T2.[AbsId] INNER JOIN JDT1 T3 ON T1.[AcctCode] = T3.[Account] INNER JOIN OASC T4 ON T1.[Project]=T4.[Code] 
where T1.[Segment_0] like '60%%' 
GROUP BY T1.[AcctCode],T1.[Segment_0],T1.[AcctName] 

此查询为我提供了不同的运营成本值。我需要类似WHEN T1.[Segment_0] LIKE '6002%%,6003%%,6004%%' THEN 'Operating Cost'。可能吗？我不需要一个接一个的喜欢。作为运营成本，我需要一切。请帮我解决这个问题。

Answer 1

如果T1.[Segment_0]只是数值您可以使用此语法与between：

case when substring(T1.[Segment_0], 1, 4) between 6001 and 6006 then 'Operating Cost' else T1.[AcctName] end 

否则，您可以使用IN：

case when substring(T1.[Segment_0], 1, 4) in ('6001','6002','6003','6004','6005','6006') then 'Operating Cost' else T1.[AcctName] end 

Answer 2

也许你的问题是，你在group byAcctName而不是case的结果。也许这你想要做什么：

SELECT T1.[AcctCode],T1.[Segment_0],SUM(T0.[DebLTotal]) AS BUDGET, SUM(T3.[Debit]) AS DEBIT, 
     AcctName = (CASE WHEN T1.[Segment_0] LIKE '6001%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6002%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6003%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6004%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6005%%' THEN 'Operating Cost' 
         WHEN T1.[Segment_0] LIKE '6006%%' THEN 'Operating Cost' 
        ELSE T1.[AcctName] END) 
FROM OBGT T0 INNER JOIN OACT 
    T1 
    ON T0.[AcctCode]=T1.[AcctCode] INNER JOIN 
    OBGS T2 
    ON T0.[Instance] = T2.[AbsId] INNER JOIN 
    JDT1 T3 
    ON T1.[AcctCode] = T3.[Account] INNER JOIN 
    OASC T4 
    ON T1.[Project] = T4.[Code] 
where T1.[Segment_0] like '60%%' 
GROUP BY T1.[AcctCode], T1.[Segment_0], 
     (CASE WHEN T1.[Segment_0] LIKE '6001%%' THEN 'Operating Cost' 
       WHEN T1.[Segment_0] LIKE '6002%%' THEN 'Operating Cost' 
       WHEN T1.[Segment_0] LIKE '6003%%' THEN 'Operating Cost' 
       WHEN T1.[Segment_0] LIKE '6004%%' THEN 'Operating Cost' 
       WHEN T1.[Segment_0] LIKE '6005%%' THEN 'Operating Cost' 
       WHEN T1.[Segment_0] LIKE '6006%%' THEN 'Operating Cost' 
       ELSE T1.[AcctName] 
      END); 

编辑：

您可能还需要从select和group by，既除去Segment_0。没有样本数据，很难说。

Answer 3

SQL服务器等做pattern matching

尝试CASE WHEN T1.[Segment_0] LIKE '600[123456]%%' THEN 'Operating Cost'
