Question

我有来自4个不同表的查询，我想将其中一个字段值连接到一个字符串，例如我想要下一个查询结果

       **BuildName         ConfigurationName    FileName          Name   RunIDMax**
   Build_20131213.5     Default configuration   Screenshot2.png    User1        354
   Build_20131213.5     Default configuration   Screenshot1.png    User1        354

将如下所示：

     **BuildName           ConfigurationName    FileName                                 Name   RunIDMax**
   Build_20131213.5     Default configuration   Screenshot2.png, Screenshot1.png       User1        354

我有以下问题：

 select * 
from (select TestPlanName, TestCaseId, AreaPath, IterationPath, TestSuiteSuitePath, ResultTestCaseId, ResultTest, ResultOutcome, max(ResultDate) as MaxResultDate , BuildName, ConfigurationName, FileName, Name, ErrorMessage, max(TA.TestRunId) as RunIDMax
from 
[Tfs_Warehouse].[dbo].[DimPerson] (nolock) AS DTRO inner join
[tfs_warehouse].dbo.TestResultView (nolock) a on  a.ResultExecutedBySK = PersonSK inner join 
[Tfs_DefaultCollection].[dbo].[tbl_Attachment] (nolock) AS TA ON a.TestRunId = TA.TestRunId inner join 

[Tfs_DefaultCollection].[dbo].[tbl_TestActionResult] (nolock) AS TAR on TA.TestRunId = Tar.TestRunId

group by TestCaseId,TestPlanName,  AreaPath, IterationPath, TestSuiteSuitePath, ResultTestCaseId, ResultTest, ResultOutcome,  BuildName, ConfigurationName, FileName, Name, ErrorMessage) 

AS b  

where 
 ResultOutcome <> 'Never Run' and (BuildName IN (@BuildName) or @BuildName = null) and (TestPlanName In (@TestPlanName) or @TestPlanName = null)
and TestSuiteSuitePath is not null  
and BuildName is not null order by RunIDMax desc

我尝试使用此查询：

select STUFF(
            (select ',' + CAST(FileName as nvarchar) 
            from [Tfs_DefaultCollection].[dbo].[tbl_Attachment]
            group by FileName
            for xml path('')
             ),1,1,'')

但我找不到将其集成到主查询中的正确方法。

尝试集成您的查询，如下所示：

(select STUFF(
        (select ',' + CAST(FileName as nvarchar) 
           from [Tfs_DefaultCollection].[dbo].[tbl_Attachment]
          group by FileName
            for xml path('')
         ),1,1,'')) AS FileName

Answer 2

with TableCTe as
(select    'Build_20131213.5'  BuildName,   'Default configuration' ConfigurationName,   'Screenshot2.png' FileName,    'User1' Name, 354 RunIDMax
union all
select    'Build_20131213.5',     'Default configuration',   'Screenshot1.png',    'User1', 354
)
,cte1 as
(
select name,
stuff((select  ','+filename from TableCTe  for xml path('') ),1,1,'')as filename 
from TableCTe
group by name
)
,cte2 as
(select row_number()  over(order by a.name )rn, a.BuildName,a.ConfigurationName,a.Name,a.RunIDMax,b.filename from TableCTe a 
inner join cte1 b on a.Name=b.Name)

select * from cte2 where rn=1

在单个字段中获取多个值
