I have same requirement once as like you have now...
See below stored procedure..
CREATE PROCEDURE [dbo].[GetSubscriptionData]
AS
BEGIN
SET NOCOUNT ON;
WITH
[Sub_Parameters] AS
(
SELECT [SubscriptionID], [Parameters] = CONVERT(XML,a.[Parameters])
FROM [Subscriptions] a
),
[MySubscriptions] AS
(
SELECT DISTINCT [SubscriptionID], [ParameterName] = QUOTENAME(p.value('(Name)[1]', 'nvarchar(max)')), [ParameterValue] = p.value('(Value)[1]', 'nvarchar(max)')
FROM [Sub_Parameters] a
CROSS APPLY [Parameters].nodes('/ParameterValues/ParameterValue') t(p)
),
[SubscriptionsAnalysis] AS
(
SELECT a.[SubscriptionID], a.[ParameterName], [ParameterValue] =
(
SELECT STUFF((SELECT [ParameterValue] + ', ' as [text()]
FROM [MySubscriptions]
WHERE [SubscriptionID] = a.[SubscriptionID] AND [ParameterName] = a.[ParameterName]
FOR XML PATH('') ),1, 0, '') +''
)
FROM [MySubscriptions] a
GROUP BY a.[SubscriptionID],a.[ParameterName]
)
SELECT
DISTINCT (a.[SubscriptionID]),
c.[UserName] AS Owner,
b.Name,
b.Path,
a.[Locale],
a.[InactiveFlags],
d.[UserName] AS Modified_by,
a.[ModifiedDate],
a.[Description],
a.[LastStatus],
a.[EventType],
a.[LastRunTime],
a.[DeliveryExtension],
a.[Version],
sch.StartDate,
--e.[ParameterName],
--LEFT(e.[ParameterValue],LEN(e.[ParameterValue])-1) as [ParameterValue],
SUBSTRING(b.PATH,2,LEN(b.PATH)-(CHARINDEX('/',REVERSE(b.PATH))+1)) AS ProjectName
FROM
[Subscriptions] a
INNER JOIN [Catalog] AS b ON a.[Report_OID] = b.[ItemID]
Inner Join ReportSchedule as RS on rs.SubscriptionID = a.SubscriptionID
INNER JOIN Schedule AS Sch ON Sch.ScheduleID = rs.ScheduleID
LEFT OUTER JOIN [Users] AS c ON a.[OwnerID] = c.[UserID]
LEFT OUTER JOIN [Users] AS d ON a.MODIFIEDBYID = d.Userid
LEFT OUTER JOIN [SubscriptionsAnalysis] AS e ON a.SubscriptionID = e.SubscriptionID;
END
This is simplified query to get all SSRS Subscriptions
SELECT USR.UserName AS SubscriptionOwner
,SUB.ModifiedDate
,SUB.[Description]
,SUB.EventType
,SUB.DeliveryExtension
,SUB.LastStatus
,SUB.LastRunTime
,SCH.NextRunTime
,SCH.Name AS ScheduleName
,CAT.[Path] AS ReportPath
,CAT.[Description] AS ReportDescription
FROM dbo.Subscriptions AS SUB
INNER JOIN dbo.Users AS USR
ON SUB.OwnerID = USR.UserID
INNER JOIN dbo.[Catalog] AS CAT
ON SUB.Report_OID = CAT.ItemID
INNER JOIN dbo.ReportSchedule AS RS
ON SUB.Report_OID = RS.ReportID
AND SUB.SubscriptionID = RS.SubscriptionID
INNER JOIN dbo.Schedule AS SCH
ON RS.ScheduleID = SCH.ScheduleID
ORDER BY USR.UserName, CAT.[Path];
if you still have any query, comment it..
