SqlServer中临时表的使用
http://www.cnblogs.com/chongzi/archive/2011/01/19/1939106.html
--存储过程中将多表连接结果写入到临时表中,然后通过游标查询临时表内容 --判断临时表是否存在 IF OBJECT_ID(‘tempdb..#TmpTable‘) IS NOT NULL DROP TABLE #TmpTable SELECT a.[a1],a.[a1],b.[b1],b.[b2] INTO #TmpTable FROM A a LEFT JOIN B b ON a.a1 = b.a1
操作游标
DECLARE @orderId NVARCHAR(50),@customerId NVARCHAR(50),@employeeId NVARCHAR(50) DECLARE myCursor CURSOR FOR SELECT o.OrderID,o.CustomerID,o.EmployeeID FROM Orders AS o OPEN myCursor fetch next from myCursor into @orderId,@customerId,@employeeId while @@fetch_status=0 BEGIN PRINT @orderId PRINT @customerId PRINT @employeeId fetch next from myCursor into @orderId,@customerId,@employeeId END close myCursor deallocate myCursor
