Question

如果我单独为两个日期运行select语句，它将返回正确的日期，但是当它包含在代码中时它不会。我需要一些帮助。

SELECT r.[Holding Co], 
       r.[Reference Order No], 
       r.Reg, 
       r.SL, 
       r.[Order Date],  
    CASE WHEN [Type]<>'Recovery' 
      AND [Status]<>'Inter' 
      AND [Status]<>'Cancelled' 
      AND [Order Date]<[Date Order] 
      AND [CICD Actual] IS NULL 
      OR [CICD Actual]>[Date Outstanding] 
     THEN 1 
     ELSE 0 End AS [Outstanding], 
    --CASE WHEN /* many more calculated fields and cases redacted for brevity ... */                                          
      Month([Date Outstanding]) AS [Month], 
      Year([Date Outstanding]) AS [Year],  
      CAST(FORMAT(GETDATE(), 'yyyy-MM-01') as Date) AS [Date Order],
      DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) AS [Date Outstanding]    

FROM unisat.Register AS r;

错误：消息207，级别16，状态1，行3无效的列名称＆＃39;日期为了＆＃39 ;.消息207，级别16，状态1，行4无效的列名称＆＃39;日期优秀＆＃39;

[日期未完成]是在SELECT列表中引入的，您不能在同一个选择列表中使用它作为其他内容的基础。

我建议将此计算（以及[日期顺序]）重构为CTE，然后您可以在外部选择中使用它，如下所示：

;with x as (
    SELECT r.[Holding Co], 
           r.[Reference Order No], 
           r.Reg, 
           r.SL, 
           r.[Order Date], 
           r.[Type] ,
           r.[Status],
           r.[CICD Actual],
          CAST(FORMAT(GETDATE(), 'yyyy-MM-01') as Date) AS [Date Order],
          DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) AS [Date Outstanding]    
    FROM unisat.Register AS r
)
SELECT x.[Holding Co], 
    x.[Reference Order No], 
    x.Reg, 
    x.SL, 
    x.[Order Date], 
    CASE WHEN x.[Type]<>'Recovery' 
        AND x.[Status]<>'Inter' 
        AND x.[Status]<>'Cancelled' 
        AND x.[Order Date]<x.[Date Order] 
        AND x.[CICD Actual] IS NULL 
        OR x.[CICD Actual]>x.[Date Outstanding] 
        THEN 1 
        ELSE 0 End AS [Outstanding], 
    CASE WHEN /* many more calculated fields and cases redacted for brevity ... */                                          
    Month(x.[Date Outstanding]) AS [Month], 
    Year(x.[Date Outstanding]) AS [Year],
    x.[Date Order],
    x.[Date Outstanding]  
from x;

SQL：列名称错误无效
