Question

请查看别名。我希望将值设置为字符串var。如何将单引号放在单引号的字符串中。

   SET @SQLString = N'SELECT purDetQty as 'detQty',stkBatchCode as 'batchCode',purDetProductId as 'productId'
               INTO #ProductTable FROM PurchaseDetail 
               INNER JOIN Stock on stkId=purDetStockId 
               WHERE purDetID=@detId'

Answer 1

您需要使用第二个引号来转义引号：

SET @SQLString = N'SELECT purDetQty as ''detQty''
      ,stkBatchCode as ''batchCode''
      ,purDetProductId as ''productId'' 
           INTO #ProductTable FROM PurchaseDetail  
           INNER JOIN Stock on stkId=purDetStockId  
           WHERE purDetID=@detId'

Answer 2

您可以将单引号放在SQL中带单引号的字符串中，加倍，即：

SET @SQLString = N'SELECT purDetQty as ''detQty'',stkBatchCode as ''batchCode'',purDetProductId as ''productId''
           INTO #ProductTable FROM PurchaseDetail 
           INNER JOIN Stock on stkId=purDetStockId 
           WHERE purDetID=@detId'

请注意，这是两个单引号（''），而不是一个双引号（“）

但是，在这种情况下，您不需要使用单引号，但应该能够简单地使用

SET @SQLString = N'SELECT purDetQty as detQty,stkBatchCode as batchCode,purDetProductId as productId
           INTO #ProductTable FROM PurchaseDetail 
           INNER JOIN Stock on stkId=purDetStockId 
           WHERE purDetID=@detId'

如何在查询字符串中添加别名。？
