–建立主表临时表 CREATE TABLE #temp ( rownumber bigint, orderseqno VARCHAR(36), goodsname VARCHAR(50), companyname VARCHAR(100) )
–建立子表临 时表 CREATE TABLE #detail ( orderseqno VARCHAR(36), detailid UNIQUEIDENTIFIER, unitprice DECIMAL(12,2), Qty int )
–插入主表数据到主表临时表 insert into #temp SELECT oo.rownumber, oo.OrderSeqNO, oo.GoodsName, oo.CompanyName FROM (SELECT ROW_NUMBER () OVER (ORDER BY oi.createdate DESC) AS rownumber, oi.OrderSeqNO, oi.GoodsName ,ci.CompanyName FROM OrderInfo oi INNER JOIN CompanyInfo ci ON oi.CompanyID=ci.CompanyID WHERE oi.CreateDate<GETDATE() ) AS oo WHERE rownumber BETWEEN 10 AND 20
–定义游标 DECLARE @temp_cursor CURSOR
–给游标赋值 SET @temp_cursor=CURSOR FOR SELECT #temp.orderseqno,#temp.goodsname FROM #temp
–定义游标循环过程中所需保存的临时数据 DECLARE @orderseqno VARCHAR(36),@goodsname varchar(50)
–打开游标 OPEN @temp_cursor
FETCH NEXT FROM @temp_cursor INTO @orderseqno,@goodsname
–循环游标,查询子表数据,然后插入子表临时表 WHILE @@FETCH_STATUS=0 BEGIN INSERT INTO #detail SELECT od.OrderSeqNO,od.OrderDetailID, od.UnitPrice,od.Qty FROM OrderDetail od WHERE od.OrderSeqNO=@orderseqno
FETCH NEXT FROM @temp_cursor INTO @orderseqno,@goodsname END
–关闭游标 CLOSE @temp_cursor DEALLOCATE @temp_cursor
SELECT * FROM #temp SELECT * FROM #detail
–删除临时表 DROP TABLE #temp DROP TABLE #detail
上面的T-SQL只在SQL Server 2005上调试成功。
