如何从两个临时表中获取数据并插入第三个表而不在 SQL 服务器中添加新行

Question

我正在尝试制作需要从两个不同表中获取数据的报告。 我不能使用加入。 所以我试图插入一个临时表。 但它为每个插入返回不止一行。 我希望它在一行中。下面是 MS Sql 服务器中的查询。

     @month int= 0,
       @year int = 0, --(2020)
       @regionid int = null, --(13/14/16/17/18/19/20)
       @countryid int = null,
       @clientid int = null
AS
BEGIN
IF OBJECT_ID('tempdb..#tempClientReport') IS NOT NULL
DROP TABLE #tempClientReport
Create Table #tempClientReport
(
Client_ID                                       int,
Client_Name                                     varchar(250),
Project_Received_Request          int default 0,
Project_Delivered_Request         int default 0,
BAU_Received_Request              int default 0,
BAU_Delivered_Request                    int default 0
)


insert into #tempClientReport(Client_ID, Client_Name, Project_Received_Request, BAU_Received_Request,Project_Delivered_Request,BAU_Delivered_Request)
       select 
       RELEASE_MANAGEMENT_TRAN.CLIENT_ID, 
       Client_Name,
       Sum(case when REQUEST_ID = 2 then 1 else 0 end) as ProjectCount,
       Sum(case when REQUEST_ID = 1 then 1 else 0 end) as BAUCount,null,null
from   
       FLOW_TRANSACTION INNER JOIN RELEASE_MANAGEMENT_TRAN on RELEASE_MANAGEMENT_TRAN.RM_ID = FLOW_TRANSACTION.RM_ID 
inner join CLIENT_MASTER
       on RELEASE_MANAGEMENT_TRAN.CLIENT_ID = CLIENT_MASTER.CLIENT_ID
where 
(@month = 0 or (DATEPART(month,RELEASE_MANAGEMENT_TRAN.CREATION_DATE) = @month))
and (DATEPART(year,RELEASE_MANAGEMENT_TRAN.CREATION_DATE) = @year)
and (@regionid is null or RELEASE_MANAGEMENT_TRAN.REGION_ID = @regionid)
and (@countryid is null or RELEASE_MANAGEMENT_TRAN.GE_ID = @countryid)
and (@clientid is null or RELEASE_MANAGEMENT_TRAN.CLIENT_ID = @clientid)
and TO_STAGEID = '11'  and STATUS != 'R' 
--and CLIENT_MASTER.ACTIVE_STATE = 'A'
group by 
       RELEASE_MANAGEMENT_TRAN.CLIENT_ID,
       Client_Name


union all

select 
       RELEASE_MANAGEMENT_TRAN.CLIENT_ID, 
       Client_Name,null,null,
       Sum(case when REQUEST_ID = 2 then 1 else 0 end) as ProjectCount,
       Sum(case when REQUEST_ID = 1 then 1 else 0 end) as BAUCount
from   
       PACKAGE_QA INNER JOIN RELEASE_MANAGEMENT_TRAN on RELEASE_MANAGEMENT_TRAN.RM_ID = PACKAGE_QA.RM_ID 
inner join CLIENT_MASTER
       on RELEASE_MANAGEMENT_TRAN.CLIENT_ID = CLIENT_MASTER.CLIENT_ID
       where 
(@month = 0 or (DATEPART(month,RELEASE_MANAGEMENT_TRAN.CREATION_DATE) = @month))
and (DATEPART(year,RELEASE_MANAGEMENT_TRAN.CREATION_DATE) = @year)
and (@regionid is null or RELEASE_MANAGEMENT_TRAN.REGION_ID = @regionid)
and (@countryid is null or RELEASE_MANAGEMENT_TRAN.GE_ID = @countryid)
and (@clientid is null or RELEASE_MANAGEMENT_TRAN.CLIENT_ID = @clientid)
and STATUS    = 'C'
group by 
       RELEASE_MANAGEMENT_TRAN.CLIENT_ID,
       Client_Name
order by Client_Name
END

select * from #tempClientReport order by Client_Name

IF OBJECT_ID('tempdb..#tempRegion') IS NOT NULL
DROP TABLE #tempRegion

它给出的结果如下

1  Media    0       NULL   2    NULL
1  Media    NULL    0      NULL 2
3  Horizon  0       NULL   1    NULL   

媒体等是我想要的客户名称，对于每个客户，它应该只在一行中提供数据，如您所见，它在这里提供了两行。请帮助

你能像这样使用 SUM 和 GROUP BY：

select 
    Client_ID, [Client_Name],                                   
    SUM([Project_Received_Request]) AS [Project_Received_Request],
    SUM([Project_Delivered_Request]) AS [Project_Delivered_Request],
    SUM([BAU_Received_Request]) AS [BAU_Received_Request],
    SUM([BAU_Delivered_Request]) AS  [BAU_Delivered_Request]
from #tempClientReport
group by Client_ID, [Client_Name]
order by [Client_Name]
