與case語句動態SQL

SET @SQL = 
     'SELECT 
     CaseStatus = 
      CASE Level1Status 
       WHEN 1100 THEN ''Case Submitted to QC'' 
       WHEN 1200 THEN ''Pending QC'' 
       WHEN 1400 THEN ''Passed QC'' 

      END,

我目前有以上的動態sql/case語句的問題，因爲我似乎無法把動態SQL字符串內，沒有人碰巧有一個解決方案來解決這個與case語句動態SQL

非常感謝

EXEC sp_executesql @SQL

這是整個代碼中，我得到的錯誤是

消息156，級別15，狀態1，行附近關鍵字「案例」 32 不正確的語法。

請澄清查詢，以便我們瞭解您正在嘗試做什麼。 –

我想創建一個報告的過濾器，如果狀態是1100,1200和1400列被添加到表中以反映字符串'提交的案例'，'待定QC'和'通過QC'，問題是因爲我的動態sql當前設置爲變量@SQL作爲字符串，我無法將字符串'Case Submitted'，'Pending QC'和'通過QC'添加到case語句謝謝 – EmperorDev

@EmperorDev它的使用動態SQL與您的代碼也工作得很好。 –

這工作正常。

Create Table #Level1Status(Id int identity ,Level1Status int) 

Insert INto #Level1Status(Level1Status) values(1100),(1200),(1400) 


      Declare @SQL Nvarchar(Max) 
      SET @SQL = 
        'SELECT 
        CaseStatus = 
         CASE Level1Status 
          WHEN 1100 THEN ''Case Submitted to QC'' 
          WHEN 1200 THEN ''Pending QC'' 
          WHEN 1400 THEN ''Passed QC'' 

         END from #Level1Status'; 
      Exec SP_ExecuteSQL @SQL

既然你串連你@SQL字符串局部變量「@xxx」，在任何情況下的thease可空，它想給任何輸出在級聯所以使用ISNULL（）或者COALESCE（）所有地方可變的你使用。
