is there a way to query future SSRS subscription schedules?

问题:

In my office, many of us use SSRS to schedule recurring reports. I want to view the schedule of upcoming report runs, for the next few days or a week, so that we can see whether 20 reports are all going to try to run at the same time. How can I accomplish that? I've created t-sql reports that show subscription information, but they only show "last run" dates and times. That's not helpful for predicting tomorrow's bottlenecks. The solution should include data-driven subscriptions too.

回答1:

SSRS stores all of its data in the ReportServer database so you'll need an account with read access to this database. This is all relevant for SSRS running in native mode. I'm also not sure if shared schedules or data-driven subscriptions will be handled by this code, but I'm pretty sure they will be. I just haven't tested them.

PLEASE NOTE: Microsoft does not recommend or support directly querying the ReportServer database. They could change the structure in the next version or update of SSRS and you likely won't get any warning. The Microsoft recommendation is to always use the SSRS web service when you need to interrogate information about reporting services.

These are the tables that are relevant for pulling out the subscription information:

• dbo.Catalog - Information about the deployed reports
• dbo.ReportSchedule - Information relating reports to schedules and schedules
• dbo.Subscriptions - Information about the subscriptions
• dbo.Schedule - Information about the schedules

The SQL below pulls out schedule interval information for all reports. It doesn't calculate the next run dates but by figuring out the interval that the schedule is supposed to run on you can write another query to generate the actual dates.

This SQL was originally written for a report that just displays a string describing the interval so the final output is probably not what you're after. It should give you a good starting point though since it does figure out all of the interval details.

--these CTEs are used to match the bitmask fields in the schedule to determine which days & months the schedule is triggered on WITH wkdays AS (     SELECT 'Sunday' AS label, 1 AS daybit     UNION ALL     SELECT 'Monday', 2     UNION ALL     SELECT 'Tuesday', 4     UNION ALL     SELECT 'Wednesday', 8     UNION ALL     SELECT 'Thursday', 16     UNION ALL     SELECT 'Friday', 32     UNION ALL     SELECT 'Saturday', 64 ), monthdays AS (     SELECT CAST(number AS VARCHAR(2)) AS label,         POWER(CAST(2 AS BIGINT),number-1) AS daybit     FROM master.dbo.spt_values     WHERE type='P' AND number BETWEEN 1 AND 31 ), months AS (     SELECT DATENAME(MM,DATEADD(MM,number-1,0)) AS label,         POWER(CAST(2 AS BIGINT),number-1) AS mnthbit     FROM master.dbo.spt_values     WHERE type='P' AND number BETWEEN 1 AND 12 ) SELECT cat.path,     cat.name,     cat.creationdate,     cat.modifieddate,     subs.Description,     subs.LastStatus,     subs.LastRunTime,     subs.InactiveFlags,     CASE RecurrenceType         WHEN 1 THEN 'Once'         WHEN 2 THEN 'Hourly'         WHEN 3 THEN 'Daily' --by interval         WHEN 4 THEN             CASE                 WHEN WeeksInterval>1 THEN 'Weekly'                 ELSE 'Daily' --by day of week             END         WHEN 5 THEN 'Monthly' --by calendar day         WHEN 6 THEN 'Monthly' --by day of week     END AS sched_type,     sched.StartDate,     sched.MinutesInterval,     sched.RecurrenceType,     sched.DaysInterval,     sched.WeeksInterval,     sched.MonthlyWeek,     wkdays.label AS wkday,wkdays.daybit AS wkdaybit,     monthdays.label AS mnthday,monthdays.daybit AS mnthdaybit,     months.label AS mnth, months.mnthbit INTO #t FROM dbo.Catalog AS cat LEFT JOIN dbo.ReportSchedule AS repsched ON repsched.ReportID=cat.ItemID LEFT JOIN dbo.Subscriptions AS subs ON subs.SubscriptionID=repsched.SubscriptionID LEFT JOIN dbo.Schedule AS sched ON sched.ScheduleID=repsched.ScheduleID LEFT JOIN wkdays ON wkdays.daybit & sched.DaysOfWeek > 0 LEFT JOIN monthdays ON monthdays.daybit & sched.DaysOfMonth > 0 LEFT JOIN months ON months.mnthbit & sched.[Month] > 0 WHERE cat.ParentID IS NOT NULL --all reports have a ParentID   /* THE PREVIOUS QUERY LEAVES MULTIPLE ROWS FOR SUBSCRIPTIONS THAT HAVE MULTIPLE BITMASK MATCHES      *  * THIS QUERY WILL CONCAT ALL OF THOSE FIELDS TOGETHER AND ACCUMULATE THEM IN A TABLE FOR USE LATER. */  CREATE TABLE #c (type VARCHAR(16) COLLATE Latin1_General_CI_AS_KS_WS, name VARCHAR(255) COLLATE Latin1_General_CI_AS_KS_WS, path VARCHAR(255) COLLATE Latin1_General_CI_AS_KS_WS, concatStr VARCHAR(2000) COLLATE Latin1_General_CI_AS_KS_WS);   WITH d AS (     SELECT DISTINCT path,         name,         mnthday AS lbl,         mnthdaybit AS bm     FROM #t ) INSERT INTO #c (type,path,name,concatStr) SELECT 'monthday' AS type,     t1.path,t1.name,     STUFF((         SELECT ', ' + CAST(lbl AS VARCHAR(MAX))         FROM d AS t2         WHERE t2.path=t1.path AND t2.name=t1.name         ORDER BY bm         FOR XML PATH(''),TYPE     ).value('.','VARCHAR(MAX)'),1,2,'') AS concatStr FROM d AS t1 GROUP BY t1.path,t1.name;  WITH d AS (     SELECT DISTINCT path,         name,         wkday AS lbl,         wkdaybit AS bm     FROM #t ) INSERT INTO #c (type,path,name,concatStr) SELECT 'weekday' AS type,     t1.path,t1.name,     STUFF((         SELECT ', ' + CAST(lbl AS VARCHAR(MAX))         FROM d AS t2         WHERE t2.path=t1.path AND t2.name=t1.name         ORDER BY bm         FOR XML PATH(''),TYPE     ).value('.','VARCHAR(MAX)'),1,2,'') AS concatStr FROM d AS t1 GROUP BY t1.path,t1.name;  WITH d AS (     SELECT DISTINCT path,         name,         mnth AS lbl,         mnthbit AS bm     FROM #t ) INSERT INTO #c (type,path,name,concatStr) SELECT 'month' AS type,     t1.path,t1.name,     STUFF((         SELECT ', ' + CAST(lbl AS VARCHAR(MAX))         FROM d AS t2         WHERE t2.path=t1.path AND t2.name=t1.name         ORDER BY bm         FOR XML PATH(''),TYPE     ).value('.','VARCHAR(MAX)'),1,2,'') AS concatStr FROM d AS t1 GROUP BY t1.path,t1.name;   /* PUT EVERYTHING TOGETHER FOR THE REPORT */  SELECT a.path,a.name,a.sched_type,     a.creationdate,a.modifieddate,     a.description AS sched_desc,     a.laststatus AS sched_laststatus,     a.lastruntime AS sched_lastrun,     a.inactiveflags AS sched_inactive,     CASE RecurrenceType         WHEN 1 THEN 'Run once on '         ELSE 'Starting on '     END + CAST(StartDate AS VARCHAR(32)) + ' ' +     CASE RecurrenceType         WHEN 1 THEN ''         WHEN 2 THEN 'repeat every ' + CAST(MinutesInterval AS VARCHAR(255)) + ' minutes.'

回答2:

Below Query can help you fetch schedule for your reports for the next day, this is built on standard metadata tables from report server database.

• dbo.Catalog - Information about the deployed reports
• dbo.ReportSchedule - Information relating reports to schedules and
  schedules
• dbo.Subscriptions - Information about the subscriptions
• dbo.Schedule - Information about the schedules

Query:

Change getDate() function to have particular day schedule.

SELECT CAT.Name       ,CAT.[Path] AS ReportPath        --,SUB.LastRunTime        ,SCH.NextRunTime       ,CONVERT(VARCHAR(10), CONVERT(datetime, SCH.NextRunTime,   1), 101) As RunDate       ,right(convert(varchar(32),SCH.NextRunTime,100),8) As RunTime       ,SUB.[Description]        ,SUB.EventType        ,SUB.LastStatus        ,SUB.ModifiedDate        ,SCH.Name AS ScheduleName      FROM reportserver.dbo.Subscriptions AS SUB       INNER JOIN reportserver.dbo.Users AS USR           ON SUB.OwnerID = USR.UserID       INNER JOIN reportserver.dbo.[Catalog] AS CAT           ON SUB.Report_OID = CAT.ItemID       INNER JOIN reportserver.dbo.ReportSchedule AS RS           ON SUB.Report_OID = RS.ReportID              AND SUB.SubscriptionID = RS.SubscriptionID       INNER JOIN reportserver.dbo.Schedule AS SCH           ON RS.ScheduleID = SCH.ScheduleID   Where CONVERT(VARCHAR(10), CONVERT(datetime, SCH.NextRunTime,   1), 101)  = CONVERT(VARCHAR(10), CONVERT(datetime, getDate()+1,   1), 101)   ORDER BY USR.UserName          ,CAT.[Path];

回答3:

you can take a look into SSRS Schedule details

回答4:

This procedure will give list of all values related to Report subscription.

here you will find startdate. and on the basis of that you can complete your task.

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 as ReportName, Convert(XML,a.[ExtensionSettings]).value('(//ParameterValue/Value[../Name="RENDER_FORMAT"])[1]','nvarchar(50)') as ReportExtension, 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
