Question

我正在编写一个存储过程，以从Microsoft Great Plains中检索购买，以便可以对其进行处理。

大平原地区有两套发票表格。 SOP10100 / SOP10200包含发票抬头和尚未过帐的发票的详细信息。 SOP30200 / SOP30300包含发票抬头和已过帐发票的详细信息。购买产品后，它将立即进入SOP10100 / SOP10200，并在发布后将其从SOP10100 / SOP10200移至SOP30200 / SOP30300。有一个公用表SOP10106，其中包含用户定义的字段，并且可以连接到任一表集。

在进行采购时，我们需要检查两个表，以防发票过帐，然后才能对其进行处理。到目前为止，我们能够实现这一目标的唯一方法是通过UNION，这基本上是两个相同的查询，不同之处在于一个查询连接到SOP10100 / SOP10200，另一个连接到SOP30200 / SOP30300。

我希望找到一种方法可以将其简化为单个查询（利用共享的SOP10106表），以期获得一个仅包含具有SOP10100 / SOP10200或SOP30200 / SOP30300记录的结果集记录。 GP表的联接在OPENQUERY函数中。

SPROC如下：

有人知道任何无需使用UNION即可简化此操作的想法吗？我希望提高性能。

我试图通过以下方式使用FULL JOIN和COALESCE来做另一种方式：

SELECT COALESCE(Table1.SOPNUMBE, Table2.SOPNUMBE) AS 'SOPNUMBE', COALESCE(Table1.ITEMNMBR, Table2.ITEMNMBR) AS 'SKU', COALESCE(Table1.CUSTNMBR, Table2.CUSTNMBR) AS 'Account_Number', [SubscriptionLog].ID
FROM (SELECT SOP10100.SOPNUMBE,SOP10200.ITEMNMBR,SOP10100.CUSTNMBR FROM [GPSERVER].CPI.dbo.SOP10100 INNER JOIN [GPSERVER].CPI.dbo.SOP10200 ON SOP10100.SOPNUMBE = SOP10200.SOPNUMBE) AS Table1
FULL JOIN (SELECT SOP30200.SOPNUMBE,SOP30300.ITEMNMBR,SOP30200.CUSTNMBR FROM [GPSERVER].CPI.dbo.SOP30200 INNER JOIN [GPSERVER].CPI.dbo.SOP30300 ON SOP30200.SOPNUMBE = SOP30300.SOPNUMBE) AS Table2 ON Table1.SOPNUMBE = Table2.SOPNUMBE AND Table1.ITEMNMBR = Table2.ITEMNMBR AND Table1.CUSTNMBR = Table2.CUSTNMBR
INNER JOIN [GPSERVER].CPI.dbo.SOP10106 WITH(NOLOCK) ON COALESCE(Table1.SOPNUMBE, Table2.SOPNUMBE) = SOP10106.SOPNUMBE
INNER JOIN [CRMSERVER].CPI_MSCRM.dbo.Account AS [Account1] WITH(NOLOCK) ON COALESCE(Table1.CUSTNMBR, Table2.CUSTNMBR) = [Account1].AccountNumber COLLATE DATABASE_DEFAULT
INNER JOIN [CRMSERVER].CPI_MSCRM.dbo.Contact WITH(NOLOCK) ON SOP10106.USERDEF1 = [Contact].cncy_customernumber COLLATE DATABASE_DEFAULT
--INNER JOIN [CRMSERVER].CPI_MSCRM.dbo.Account AS [Account2] WITH(NOLOCK) ON [Contact].ParentCustomerId = [Account2].Id
INNER JOIN CPIProcessData.dbo.StringMap AS [StringMapMarket] WITH(NOLOCK) ON [Account1].cncy_MarketType = [StringMapMarket].AttributeValue AND [StringMapMarket].AttributeName = 'cncy_MarketType' AND [StringMapMarket].ObjectTypeCode = 2
INNER JOIN CPIProcessData.dbo.StringMap AS [StringMapCountry] WITH(NOLOCK) ON [Contact].cncy_address1country = [StringMapCountry].AttributeValue AND [StringMapCountry].AttributeName = 'cncy_address1country' AND [StringMapMarket].ObjectTypeCode = 2
INNER JOIN CPIProcessData.dbo.vwLmsMapping AS MAP WITH(NOLOCK) ON MAP.Subscription = 'true' AND 
                        CASE 
                            WHEN [StringMapCountry].Value IN ('US','Canada') THEN RTRIM(COALESCE(Table1.ITEMNMBR, Table2.ITEMNMBR)) + '-' + 
                                CASE
                                   WHEN [StringMapMarket].Value IN ('HE','MH') THEN 'HE'
                                   WHEN [StringMapMarket].Value IN ('ED') THEN 'ED'
                                   ELSE 'HS'
                                END
                            ELSE RTRIM(COALESCE(Table1.ITEMNMBR, Table2.ITEMNMBR)) 
                        END = map.SKU
LEFT OUTER JOIN [SubscriptionLog] WITH(NOLOCK) ON SOP10106.SOPNUMBE = [SubscriptionLog].Invoice AND RTRIM(COALESCE(Table1.ITEMNMBR, Table2.ITEMNMBR)) = [SubscriptionLog].SKU
WHERE [SubscriptionLog].ID IS NULL

运行起来似乎更好一些，但是它返回重复项，而不是我期望的结果。

在没有UNION的情况下获取两个数据集的结果
