SSRS: How to find which reports have subreports? - sql-server

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%'

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);
