Question

我的sql脚本出了什么问题？它总是说不正确的语法。

Select Case 
When(DAY(GETDATE()) <= 23 and DAY(GETDATE()) >= 9) Then Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'9'
When(DAY(GETDATE()) <= 8 and DAY(GETDATE()) >= 24) Then  Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'24'

根据当前日期显示2012-11-9或2012-11-24。

Answer 1

可能你错过了end，试试这个：

Select Case 
         When(DAY(GETDATE()) <= 23 and DAY(GETDATE()) >= 9) 
           Then Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'9'
         When(DAY(GETDATE()) <= 8 and DAY(GETDATE()) >= 24) 
           Then  Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'24'
       end as Date1
from YourTable

Answer 2

您需要End您的案例

Select Case 
    When(DAY(GETDATE()) <= 23 and DAY(GETDATE()) >= 9) Then Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'9'
    When(DAY(GETDATE()) <= 8 and DAY(GETDATE()) >= 24) Then  Convert(varchar(10),YEAR(getdate()))+'-'+Convert(varchar(10),MONTH(getdate()))+'-'+'24'
End

Answer 3

除了遗失的end之外，您的case条件之一永远不会成为现实

When(DAY(GETDATE()) <= 8 and DAY(GETDATE()) >= 24)

使用

   case when DAY(GETDATE()) between 9 and 23 then CONVERT(varchar(8),getdate(),120) + '9'
        else CONVERT(varchar(8),getdate(),120) + '24'
   end

此外，您的逻辑看起来可能是可疑的。你真的想在十月二十四日回到10月2日和30日吗？
