表變量存儲Procudure

Question

您好我開發中，我宣佈所謂@TEMP_TABLE的表變量的存儲過程，但此行

SET @SQL1 = 'UPDATE PO_STAGE set PO_STAGE.ISVALID = ''N'' 
FROM ERP_ADMIN.'+@STAGE_TABLE+' PO_STAGE, @TEMP_TABLE TMP 
where PO_STAGE.ERP_PO_ID = TMP.ERP_POID' 
exec (@SQL1) 

我得到「必須聲明表變量‘@TEMP_TABLE’ 「。錯誤。 請在這方面幫助我。下面是存儲過程的代碼。

Answer 1

您應該通過@TEMP_TABLE作爲參數。要通過表參數，你應該先創建表型：

IF NOT EXISTS (SELECT 1 FROM sys.types WHERE NAME = 'TEMP_TABLE_TYPE')  
     CREATE TYPE TEMP_TABLE_TYPE AS TABLE(
      ERP_POID nvarchar(50), 
      ERRORCD nvarchar(50), 
      ERRORMSG nvarchar(120) 
    ); 

並使用它：

exec sp_executesql @Sql, N'@TEMP_TABLE TEMP_TABLE_TYPE readonly', @TEMP_TABLE 

對於epxplonation你可以使用這個鏈接Passing table variable into dynamic sql。

如果你覺得這種方式不是很明顯，我建議使用臨時表而不是表varible：

CREATE TABLE #TEMP_TABLE (
      ERP_POID nvarchar(50), 
      ERRORCD nvarchar(50), 
      ERRORMSG nvarchar(120) 
    );
