Question

当我为采购订单生成报表时，报表会复制产品代码的记录。

例如，采购订单是：P000976，报告只显示一次产品代码两次。 45-5540出现两次。

P000976 09-17-2012 15,040.00 15,040.00 0.00
45-5540“Lordotic Cervical Spacer 10mm Lordotic Cervical Spacer 10mm“20 20 0
45-5540“Lordotic Cervical Spacer 10mm Lordotic Cervical Spacer 10mm“20 20 0

当我将报表的SQL放在SQL服务器中并通过查看代码导致其他产品代码的位置来运行sql时，它就是SQL中的这一行：

在q.distpartno = p.distpartno上加入all_product_codes_VW p

select q.specialrequirement
, q.distpartno
, q.toproduce
, q.prodbegindate
, q.distributor
, rc.report_category_name
, s.productperpo
, r.ebi_released
, w.ebi_in_WIP
, p.distproductname
, tp.typeprefixdetail
, tp.cost
, '1' as ReportTotals

from all_required_vw q
left join all_shipped_grafts_new_VW s on (q.distpartno = s.distpartno and  q.specialrequirement = s.ponumber)
left join all_released_Grafts_VW r on q.distpartno = r.distpartno
left join all_in_WIP_VW w on q.distpartno = w.distpartno
join all_product_codes_VW p on q.distpartno = p.distpartno
join setup_tissue_prefix tp on q.typenumber = tp.typeprefix
join setup_report_category_1 rc on q.distributor = rc.report_category_id

where q.prodbegindate < @enddate
           and q.completed = '0'
            and rc.report_category_name  like  '%' + isnull(@tcustomer, '') + '%'
order by q.prodbegindate, p.distproductname

这是连接创建副本的视图的SQL。

SELECT COUNT_BIG(*) AS BIG, DistPartNo, DistProductName, Distributor, UMTBProductCode
FROM  dbo.Setup_Distributor_Product_info
WHERE (Distributor <> '7') OR (Distributor IS NULL)
GROUP BY DistPartNo, DistProductName, Distributor, USSAProductCode

Answer 1

如果你注释掉这些行

--, p.distproductname

--join all_product_codes_VW p on q.distpartno = p.distpartno

查询是否为每个distpartno返回单行？如果是，那么你是对的，因为all_products_code_VW视图导致了多行。

运行这两个查询并查看每个查询中有多少行，它将为您提供以下原因的线索：

Select * from all_required_vw where distpartno = '45-5540'
Select * from all_product_codes_VW where distpartno = '45-5540'

我的猜测是，只加入distpartno并不足以给你独特的结果。同一部件可能有多个分销商，或同一部件号可能有多个产品名称，例如不同的产品分销商使用相同的部件号和不同的产品。

Answer 2

可能是这个GROUP BY子句

GROUP BY DistPartNo, DistProductName, Distributor, USSAProductCode

需要替换

GROUP BY DistPartNo, DistProductName, Distributor, UMTBProductCode

SSRS 2005报告重复记录
