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) AS oo
WHERE rownumber BETWEEN 10 AND 20

DECLARE @temp_cursor CURSOR

–给游标赋值

SET @temp_cursor=CURSOR FOR SELECT #temp.orderseqno,#temp.goodsname FROM #temp

DECLARE @orderseqno VARCHAR(36),@goodsname varchar(50)

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。
