Question

我有一个查询，它给我语法错误。我没有得到它。请帮忙整理一下。

SELECT 
    T3.[AcctName],
    SUM(T0.[DebLTotal]/85) AS buget,(Select sum(T3.[Debit]/85) From JDT1 T3 ) as 'CurrentBudget'
FROM 
    OBGT T0
INNER JOIN
    (SELECT 
         CASE WHEN T1.[AcctCode] = '5001' THEN T1.[AcctName] = 'Salaries'
         END as [AcctName],
         [AcctCode]
     FROM 
         OACT AS T1) AS T3 ON T0.[AcctCode] = T3.[AcctCode]
INNER JOIN 
    OBGS T2 ON T0.[Instance] = T2.[AbsId]
WHERE
    T2.[Name] = 'Main Budget 2015'
GROUP BY 
    T3.[AcctName], T2.[Name]

我在这一行收到Incorrect syntax near '='错误

SELECT CASE WHEN T1.[AcctCode] = '5001' THEN T1.[AcctName] = 'Salaries'

Answer 1

问题是你在CASE表达式中间的作业：

SELECT 
     CASE WHEN T1.[AcctCode] = '5001' THEN T1.[AcctName] = 'Salaries'
     END as [AcctName],
     [AcctCode]
 FROM 
     OACT AS T1

这将永远不会有效，因为CASE只是T-SQL中的表达式 - 它只能返回一个原子值 - 它无法进行分配或控制代码流。

您需要使用以下内容：

SELECT 
     [AcctName] = CASE 
                     WHEN [AcctCode] = N'5001' THEN 'Salaries'
                     ELSE 'Other'
                  END,
     [AcctCode]
 FROM 
     OACT AS T1

如果您的AcctCode是5001 - 那么您使用Salaries作为AcctName（如果它是另一个值 - 您想做什么？）

更新：不确定仅执行其他部分的意思 - 请查看此演示：

DECLARE @t1 TABLE (ID INT NOT NULL, AcctCode INT)

INSERT INTO @T1 VALUES(1, 5000), (2, 5001), (3, 5000), (4, 5002), (5, 5001), (6, 4999)

SELECT 
     [AcctName] = CASE 
                     WHEN [AcctCode] = 5001 THEN 'Salaries'
                     ELSE 'Other'
                  END,
     [AcctCode]
 FROM @T1

输出将清楚地显示我的CASE表达式正常工作 - 对于5001，AcctName的值设置为Salaries，而对于所有其他值，它返回Other。

这可能是因为你把'围绕一个数字？尝试将其写为T1.[AcctCode] = 5001

Answer 3

这应解决您的问题，以下行不正确

 SELECT CASE WHEN T1.[AcctCode] = '5001' THEN T1.[AcctName] = 'Salaries'



  SELECT  T3.[AcctName] ,
        SUM(T0.[DebLTotal] / 85) AS buget ,
        ( SELECT    SUM(T3.[Debit] / 85)
          FROM      JDT1 T3
        ) AS 'CurrentBudget'
FROM    OBGT T0
        INNER JOIN ( SELECT CASE WHEN T1.[AcctCode] = '5001' THEN 'Salaries'
                                 ELSE T1.[AcctName]
                            END AS [AcctName] ,
                            [AcctCode]
                     FROM   OACT AS T1
                   ) AS T3 ON T0.[AcctCode] = T3.[AcctCode]
        INNER JOIN OBGS T2 ON T0.[Instance] = T2.[AbsId]
WHERE   T2.[Name] = 'Main Budget 2015'
GROUP BY T3.[AcctName] ,
        T2.[Name]

Answer 4

我只得到这个查询的其他部分。

SELECT  
    T3.[AcctName] ,
    SUM(T0.[DebLTotal] / 85) AS buget ,
    (SELECT SUM(T3.[Debit] / 85)
     FROM JDT1 T3) AS 'CurrentBudget'
 FROM    
     OBGT T0
 INNER JOIN 
     (SELECT 
          AcctName = CASE 
                         WHEN T1.[AcctCode] = '10' THEN 'Fixed Assets'
                         WHEN T1.[AcctCode] = '50' THEN 'Salaries'
                         ELSE 'Other'
                     END,
          [AcctCode]
      FROM   
          OACT AS T1) AS T3 ON T0.[AcctCode] = T3.[AcctCode]
INNER JOIN 
    OBGS T2 ON T0.[Instance] = T2.[AbsId]
WHERE   
    T2.[Name] = 'Main Budget 2015'
GROUP BY 
    T3.[AcctName], T2.[Name]

只有ELSE 'Other'正在运作。无论我放在我的CASE WHEN中，它都会给我一行，就像：

AcctName budget
Other     2312836
