我的代码：

IF OBJECT_ID('tempdb..#Temp15') IS NOT NULL BEGIN
       drop table #Temp15
    end

SELECT * into #Temp15

IF OBJECT_ID('tempdb..#Temp7') IS NOT NULL BEGIN
       drop table #Temp7
end
SELECT * into #Temp7

IF OBJECT_ID('tempdb..#Temp3') IS NOT NULL BEGIN

end

SELECT * into #Temp3

LEFT OUTER JOIN SCRELATIONM1 ON CM3RM1.NUMBER = SCRELATIONM1.DEPEND COLLATE SQL_Latin1_General_CP1_CI_AS
WHERE CM3RM1.NUMBER IN ('C45168')
)
as databases (tempid, chgnr, CH_OP, Service)

select
 isnull(#Temp15.SD_NR, '') as [Interaction ID]
,isnull(LEFT(CONVERT(VARCHAR, #Temp15.SD_OP, 120), 16), '') as [Interaction Opened]
,isnull(LEFT(CONVERT(VARCHAR, #Temp3.CH_OP, 120), 16), '') as [Escalated Ticket ]

from #Temp3 full join #Temp1 on #Temp3.tempid = #Temp1.tempid
full join #Temp2 on #Temp3.tempid = #Temp2.tempid
full join #Temp4 on #Temp3.tempid = #Temp4.tempid

full join #Temp6 on #Temp3.tempid = #Temp6.tempid
full join #Temp7 on #Temp3.tempid = #Temp7.tempid
full join #Temp15 on #Temp3.tempid = #Temp15.tempid

我希望以这样的方式连接几个临时表，根据哪个表具有最大记录，它总是产品最大行数。使用上面的代码，它会产生意外的数据移位。 请看屏幕截图的样子：

无法使用左连接，因为没有规则哪个列的行数最多。 某个特定列（该示例中为[更改ID]）永远不为空，并且始终具有一行。 其他人有时可能是空的。

我尝试用不同的查询重现问题，因为它被建议。当我使用如下代码分别运行两个临时表时：

IF (SELECT object_id('TempDB..#t3')) IS NOT NULL
BEGIN
    DROP TABLE #t3
END

create table #t3 (id int, tasknr varchar(50), cat varchar(50), taskop datetime, taskcl datetime)
insert into #t3 (id, tasknr, cat, taskop, taskcl)

select
cast(ROW_NUMBER() OVER(PARTITION BY parent_change ORDER BY number)as int) as id
,number as tasknr
,category as cat
,orig_date_entered as taskop
,case when (CM3TM1.status = 'closed') then CM3TM1.date_entered else NULL end as taskcl
FROM CM3TM1
WHERE parent_change IN ('C45168')
and category = 'NEU Development' 

select * from #t3

IF (SELECT object_id('TempDB..#t4')) IS NOT NULL
BEGIN
    DROP TABLE #t4
END

create table #t4 (id int, tasknr varchar(50), cat varchar(50), taskop datetime, taskcl datetime)
insert into #t4 (id, tasknr, cat, taskop, taskcl)

select
cast(ROW_NUMBER() OVER(PARTITION BY parent_change ORDER BY number)as int) as id
,number as tasknr
,category as cat
,orig_date_entered as taskop
,case when (CM3TM1.status = 'closed') then CM3TM1.date_entered else NULL end as taskcl
FROM CM3TM1
WHERE parent_change IN ('C45168')
and category = 'NEU Impl. to Production' 

select * from #t4

它看起来是正确的但当我在查询中运行它时如下：

IF (SELECT object_id('TempDB..#t1')) IS NOT NULL
BEGIN
    DROP TABLE #t1
END

create table #t1 (id int, chgnr varchar(50))
insert into #t1 (id, chgnr)

select
cast(ROW_NUMBER() OVER(PARTITION BY number ORDER BY number)as int) as id
,number as chgnr
FROM CM3RM1
WHERE number IN ('C45168')

IF (SELECT object_id('TempDB..#t2')) IS NOT NULL
BEGIN
    DROP TABLE #t2
END

create table #t2 (id int, SD_NR varchar(50), SD_OP datetime, SD_CL datetime)
insert into #t2 (id, SD_NR, SD_OP, SD_CL)

select
cast(ROW_NUMBER() OVER(PARTITION BY CM3RM1.NUMBER ORDER BY INCIDENTSM1.OPEN_TIME)as int) as id
,INCIDENTSM1.INCIDENT_ID AS SD_NR
,INCIDENTSM1.OPEN_TIME AS SD_OP
,INCIDENTSM1.CLOSE_TIME AS SD_CL
FROM INCIDENTSM1
LEFT OUTER JOIN SCRELATIONM1 ON INCIDENTSM1.INCIDENT_ID = SCRELATIONM1.SOURCE COLLATE SQL_Latin1_General_CP1_CI_AS
LEFT OUTER JOIN CM3RM1 ON CM3RM1.NUMBER = SCRELATIONM1.DEPEND
WHERE CM3RM1.NUMBER IN ('C45168')

IF (SELECT object_id('TempDB..#t3')) IS NOT NULL
BEGIN
    DROP TABLE #t3
END

create table #t3 (id int, tasknr varchar(50), cat varchar(50), taskop datetime, taskcl datetime)
insert into #t3 (id, tasknr, cat, taskop, taskcl)

select
cast(ROW_NUMBER() OVER(PARTITION BY parent_change ORDER BY number)as int) as id
,number as tasknr
,category as cat
,orig_date_entered as taskop
,case when (CM3TM1.status = 'closed') then CM3TM1.date_entered else NULL end as taskcl
FROM CM3TM1
WHERE parent_change IN ('C45168')
and category = 'NEU Development' 

IF (SELECT object_id('TempDB..#t4')) IS NOT NULL
BEGIN
    DROP TABLE #t4
END

create table #t4 (id int, tasknr varchar(50), cat varchar(50), taskop datetime, taskcl datetime)
insert into #t4 (id, tasknr, cat, taskop, taskcl)

select
cast(ROW_NUMBER() OVER(PARTITION BY parent_change ORDER BY number)as int) as id
,number as tasknr
,category as cat
,orig_date_entered as taskop
,case when (CM3TM1.status = 'closed') then CM3TM1.date_entered else NULL end as taskcl
FROM CM3TM1
WHERE parent_change IN ('C45168')
and category = 'NEU Impl. to Production' 

select #t2.SD_NR, #t2.SD_OP, #t1.chgnr, #t3.tasknr devtasknr, #t3.taskop devtaskop, #t4.tasknr prodtasknr, #t4.taskop prodtaskop
from #t1
full join #t2 on #t2.id = #t1.id
full join #t3 on #t3.id = #t1.id
full join #t4 on #t4.id = #t1.id

看起来不正确，请在此处查看比较：http://snag.gy/N1HeI.jpg

为什么T85341和T85179在id = 2时都不在同一行？

有谁能告诉我如何解决这个问题？
