本人工作单位是一家橡塑产品制造企业，05年2月单位领导要求我开发一个生产流程数据核对表，用来稽核流程数据的准确性，其报表基本原理如下：

后续工序今日正品数 + 后续工序今日废品数 = 本工序今日正品数 + 本工序今日留存数 - 本工序昨日留存数

了解了原理后马上开工，第一次考虑用临时表：


select distinct LEFT(productid, 4) + '00' as productid into #productid from yuancaiFlow_view
where productiondate = '2004-3-1'
and productid like '01____'
go
select a.productid,
       b.productname,
       isnull(hj.GoodQty, 0) as hj_good,
       isnull(hjtoday.qty, 0) as hj_today,
       isnull(hjyesterday.qty, 0) hj_yesterday,
       isnull(hj.GoodQty, 0) - isnull(hjtoday.qty, 0) + isnull(hjyesterday.qty, 0) - isnull(sx.GoodQty, 0) - isnull(sx.BadQty, 0) as hj_difference,
       isnull(sx.GoodQty, 0) as sx_good,
       isnull(sx.BadQty, 0) as sx_bad,
       isnull(sxtoday.qty, 0) as sx_today,
       isnull(sxyesterday.qty, 0) sx_yesterday,

       isnull(jtyesterday.qty, 0) jt_yesterday,
       isnull(jt.GoodQty, 0) - isnull(jttoday.qty, 0) + isnull(jtyesterday.qty, 0) - isnull(ph.GoodQty, 0) - isnull(ph.BadQty, 0) as jt_difference,

       isnull(ph.GoodQty, 0) - isnull(phtoday.qty, 0) + isnull(phyesterday.qty, 0) - isnull(zj.GoodQty, 0) - isnull(zj.BadQty, 0) as ph_difference,
