SSRS: How to find which reports have subreports?

Question

I have a lot of SQL Server Reporting Services (SSRS) reports (*.rdl). I want to know which of these reports are using subreports. How can I do that? Looking at an easier way instead of opening each report and figuring out if a subreport is being used.

Thanks

Answer 1

I think this should provide you with what you need (With thanks to Bret Stateham ):

 --The first CTE gets the content as a varbinary(max)
 --as well as the other important columns for all reports,
 --data sources and shared datasets.
 WITH ItemContentBinaries AS
 (
   SELECT
      ItemID,Name,[Type]
     ,CASE Type
        WHEN 2 THEN 'Report'
        WHEN 5 THEN 'Data Source'
        WHEN 7 THEN 'Report Part'
        WHEN 8 THEN 'Shared Dataset'
        ELSE 'Other'
      END AS TypeDescription
     ,CONVERT(varbinary(max),Content) AS Content
   FROM ReportServer.dbo.Catalog
   WHERE Type IN (2,5,7,8)
 ),
 --The second CTE strips off the BOM if it exists...
 ItemContentNoBOM AS
 (
   SELECT
      ItemID,Name,[Type],TypeDescription
     ,CASE
        WHEN LEFT(Content,3) = 0xEFBBBF
          THEN CONVERT(varbinary(max),SUBSTRING(Content,4,LEN(Content)))
        ELSE
          Content
      END AS Content
   FROM ItemContentBinaries
 )
 --The outer query gets the content in its varbinary, varchar and xml representations...
 ,VarcharContent as
 (
 SELECT
    ItemID,Name,[Type],TypeDescription
   ,Content --varbinary
   ,CONVERT(varchar(max),Content) AS ContentVarchar --varchar
   ,CONVERT(xml,Content) AS ContentXML --xml
 FROM ItemContentNoBOM
 )
 SELECT * FROM VarcharContent where ContentVarchar like '%<subreport%'

Answer 2

The following query below will return a list of deployed reports that have subreports. Here's the Microsoft reference and a link for referencing older versions of SSRS . It looks like the only difference is changing the version of SSRS in XMLNAMESPACES part of the CTE.

Query to return all subreports

WITH
XMLNAMESPACES 
( 
    'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' AS rdl
)
, 
report_list
AS
(
    SELECT 
          [ReportID] = cat.[ItemID]
        , [ReportName] = cat.[Name]
        , [ReportPath] = cat.[Path]
        , [xmlColumn] = CAST(CAST(cat.[Content] AS VARBINARY(MAX)) AS XML)
    FROM  
        [ReportServer].[dbo].[Catalog] AS cat
    WHERE 
        1=1
        AND cat.[Content] IS NOT NULL
        AND cat.[Type] = 2 
)
SELECT 
      rpt.[ReportID]
    , rpt.[ReportName]
    , rpt.[ReportPath]
    , [SubReportName] = srpt.x.value('(//rdl:ReportName)[1]', 'NVARCHAR(256)')
FROM 
    report_list AS rpt
    CROSS APPLY xmlColumn.nodes('//rdl:Subreport') AS srpt(x);
