从 ReportServer 获取 SSRS 数据源

Question

旧 SSRS 上的内务管理，这个特定的服务器是 2008R2。

我有下面的查询，它为我提供了所有报告的名称、位置、创建和修改概述。我还想至少包含“连接字符串”，如果可能的话，还想从数据源属性中包含一些其他详细信息。但是我在 ReportServer 中找不到它。我见过人们使用 PowerShell 将其从 SSRS Web 服务中删除，我希望找到一个 T-SQL 解决方案。

如何使用 SQL 查询显示数据源详细信息？

--List all the reports on SSRS via "ReportServer" database 

USE [ReportServer]
GO
SELECT Name
--, [ItemID] --Primary key
, [Path]
, [Description]
--, [CreatedByID] --need link to get anything usable from here
, Created.UserName as CreatedByUser
, [CreationDate]
--, [ModifiedByID] --need link to get anything usable from here
, Modified.UserName as ModifiedByUser
, [ModifiedDate]


FROM [dbo].[Catalog]
left join (select [UserID]
            , [UserName]
            from [dbo].[Users]) as Created
        on Catalog.CreatedByID = Created.UserID
left join (select [UserID]
            , [UserName]
            from [dbo].[Users]) as Modified
        on Catalog.ModifiedByID = Modified.UserID

WHERE [Type] = 2 -- value per foundation Source http://sqlsrv4living.blogspot.com/2014/01/ssrs-get-list-of-all-reports-using.html

ORDER BY [Path], Name

从 ReportServer 获取 SSRS 数据源

我还想至少包括“连接字符串”

如何使用 SQL 查询显示数据源详细信息？

用于获取SSRS数据源的连接字符串的TSQL

-- Transact-SQL script to get connection string of all SSRS Shared Datasources.

/*
Let's say you want to move a database to an other SQL Server, but which of the SSRS Shared Datasources uses this database and must be changed afterwards?
With this Transact-SQL query for ReportServer database you get the connection string of all Shared Datasources,
to document the usage or to search for a specific server/database.

Please remark: Querying the ReportServer database directly is not a supported way.
Works with SSRS 2005 and higher version ReportServer databases.
Requieres select rights on the "Catalog" table in ReportServer database.
*/

-- Connection strings of all SSRS Shared Datasources
;WITH XMLNAMESPACES  -- XML namespace def must be the first in with clause.
    (DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2006/03/reportdatasource'
            ,'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner'
     AS rd)
,SDS AS
    (SELECT SDS.name AS SharedDsName
           ,SDS.[Path]
           ,CONVERT(xml, CONVERT(varbinary(max), content)) AS DEF
     FROM dbo.[Catalog] AS SDS
     WHERE SDS.Type = 5)     -- 5 = Shared Datasource

SELECT CON.[Path]
      ,CON.SharedDsName
      ,CON.ConnString
FROM
    (SELECT SDS.[Path]
           ,SDS.SharedDsName
           ,DSN.value('ConnectString[1]', 'varchar(150)') AS ConnString
     FROM SDS
          CROSS APPLY 
          SDS.DEF.nodes('/DataSourceDefinition') AS R(DSN)
     ) AS CON
-- Optional filter:
-- WHERE CON.ConnString LIKE '%Initial Catalog%=%TFS%'
ORDER BY CON.[Path]
        ,CON.SharedDsName;

这是使用 TSQL 添加数据源名称的查询：

USE [ReportServer]
GO

SELECT CATALOG.NAME
    ,CATALOG.[Path]
    ,DataSource.NAME datasource
    ,CATALOG.[Description]
    ,Created.UserName AS CreatedByUser
    ,CATALOG.[CreationDate]
    ,Modified.UserName AS ModifiedByUser
    ,CATALOG.[ModifiedDate]
FROM [dbo].[Catalog]
LEFT JOIN (
    SELECT [UserID]
        ,[UserName]
    FROM [dbo].[Users]
    ) AS Created ON CATALOG.CreatedByID = Created.UserID
LEFT JOIN (
    SELECT [UserID]
        ,[UserName]
    FROM [dbo].[Users]
    ) AS Modified ON CATALOG.ModifiedByID = Modified.UserID
JOIN DataSource ON CATALOG.ItemID = DataSource.ItemID
JOIN CATALOG cat1 ON DataSource.Link = cat1.ItemID
WHERE CATALOG.[Type] = 2
ORDER BY [Path]
    ,NAME

Answer 2

你不能。

当您将数据源和报告定义上传到报告服务器时，它会将它们的信息存储在 dbo.Catalog 表中，您可以使用 Convert(Xml, Convert(Varbinary(Max), Content)) 看到该表，因为它是 XML，您可以使用 XPath拉出你感兴趣的领域。

一旦您修改了 SSRS Web GUI 上的任何内容，问题就会真正开始。

如果您更改共享数据源中的连接字符串，或修改报表的数据源，那么 SSRS 将保留目录条目原样，而是将条目添加到 dbo.DataSource 表，并使用加密的 ConnectionString 保存更新的内容。

虽然您不能在这里解密它，但您可以提取一些连接字符串，然后标记过时的；但我一直无法找到它如何存储旧/新内容之间的链接。

之前在 Ask SSC 上也讨论过这一点，他们得出了基本相同的结论https://ask.sqlservercentral.com/questions/20328/decrypting-datasources-in-ssrs.html

当他们讨论相同的http://www.sqlservercentral.com/Forums/Topic1312030-150-1.aspx时，有一组部分脚本用于在 SSC 本身上调用 Web API 和 WMI

我鼓励您翻转问题并尝试提出 PowerShell 解决方案，因为随着 SQL Server 的复杂性不断增加，尝试在 T-SQL 中执行所有操作已不再可行。
