水平加入两个查询

Question

我在下面写了两个查询,每个查询产生一行数据.

将它们组合在一起的最佳方法是什么,以便我LEFT只使用一行数据？

这FROM两个DISTINCT databases命名为:[ASN01]和[dsi_ASN_dsicx]

我有70对像这样的数据库,但为了简单起见只显示了一对.

三个字母的首字母缩略词ASN对于两个数据库名称都是通用的这一事实并非错误,如果需要可以是解决方案的一部分.

目前的结果:

网站,Elligence(标题)ASN,100.00

网站,GP_Total(标题)ASN,120.00

期望的结果:

网站,GP_Total,Elligence(标题)ASN,120.00,100.00

SELECT  'ASN' AS Site ,
        CASE SUM(perdblnc)
          WHEN NULL THEN 0
          ELSE -1 * SUM(PERDBLNC)
        END AS GP_Total
FROM    [ASN01].[dbo].[GL10110] T1
        LEFT OUTER JOIN [ASN01].[dbo].[GL00105] T2 ON [T1].[ACTINDX] = [T2].[ACTINDX]
WHERE   YEAR1 = 2012
        AND PERIODID IN ( '2' )
        AND ACTNUMST IN ( '4200-0000-C', '6940-0000-C', '6945-0000-C',
                          '6950-0000-C' )

SELECT  'ASN' AS [Site] ,
        SUM(pi.amount) AS [Elligence]
FROM    [dsi_ASN_dsicx].dbo.charge c
        LEFT JOIN [dsi_ASN_dsicx].dbo.paymentitem pi ON c.idcharge = pi.chargeid
        LEFT JOIN [dsi_ASN_dsicx].dbo.payment p ON pi.paymentid = p.idpayment
        LEFT JOIN [dsi_ASN_dsicx].dbo.paymenttype pt ON p.paymenttypeid = pt.idpaymenttype
WHERE   pi.amount != 0
        AND pt.paymentmethod NOT IN ( '5', '7' )
        AND pt.paymentmethod IS NOT NULL
        AND p.sdate >= '20120201'
        AND p.sdate <= '20120229'

Answer 1

在不通过并更改任何查询的情况下,最简单的方法是使用"WITH"common_table_expression来使用临时表.Table1和Table2是从select语句创建的临时表.因此,我们选择table1并连接table2.

如果有任何语法问题,请告诉我,目前我没有任何测试方法.

;With Table1 as (SELECT 'ASN' as Site, Case sum(perdblnc) 
WHEN NULL THEN 0 
ELSE -1*sum(PERDBLNC) END as GP_Total  
FROM [ASN01].[dbo].[GL10110] T1
Left Outer Join [ASN01].[dbo].[GL00105]  T2
ON [T1]. [ACTINDX]= [T2]. [ACTINDX]
WHERE YEAR1 = 2012
AND PERIODID in ('2')
AND ACTNUMST in ('4200-0000-C', '6940-0000-C', '6945-0000-C', '6950-0000-C'))

, Table2 as (SELECT 
    'ASN' as [Site],
    SUM(pi.amount) as [Elligence]
FROM [dsi_ASN_dsicx].dbo.charge c
    LEFT JOIN [dsi_ASN_dsicx].dbo.paymentitem pi on c.idcharge = pi.chargeid
    LEFT JOIN [dsi_ASN_dsicx].dbo.payment p on pi.paymentid = p.idpayment
    LEFT JOIN [dsi_ASN_dsicx].dbo.paymenttype pt on p.paymenttypeid = pt.idpaymenttype
WHERE pi.amount != 0
AND pt.paymentmethod not in ('5','7')
AND pt.paymentmethod is not null
AND p.sdate >='20120201' and p.sdate <= '20120229')

SELECT * FROM Table1
LEFT JOIN Table2 ON Table1.site = Table2.site

希望这可以帮助!如果是=)则标记为答案
