sqlserver循环

sql循环，除了游标还有如下

     --   --创建临时表
			         --   DECLARE @tradeID INT;
            --if not object_id(‘Tempdb..#A‘) is null
            --     drop table #A

            --Create table #A([TradeID] nvarchar(100))
            --Insert #A SELECT TradeID FROM dbo.CRM_AntiFakeQRec GROUP BY TradeID
            --WHILE EXISTS(SELECT TradeID FROM #A)
            --BEGIN
            --SET ROWCOUNT 1
            --SELECT @tradeID=TradeID FROM #A
            --SET ROWCOUNT 0
            --DELETE FROM #A WHERE [email protected]
            --PRINT @tradeID
