【www.gdgbn.com--领导】

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(sx.GoodQty, 0) - isnull(sxtoday.qty, 0) + isnull(sxyesterday.qty, 0) - isnull(jt.GoodQty, 0) - isnull(jt.BadQty, 0) as sx_difference,
         isnull(jt.GoodQty, 0) as jt_good,
         isnull(jt.BadQty, 0) as jt_bad,
         isnull(jttoday.qty, 0) as jt_today,
         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,
