Question

I have a data driven subscription which delivers a report to an email alias at specific time.
In a subscription query:

select WorkProjectionReportTime,WorkProjectionReportToMailAlias,
'Work Projection Report for the period ' + CONVERT(varchar(10),GETDATE()-31,101)+ ' to '+CONVERT(varchar(10),GETDATE()-1,101) as Subject,
CONVERT(varchar(10),GETDATE()-31,101) as FromDate,CONVERT(varchar(10),GETDATE()-1,101) as ToDate, 60 as WO, 
'Please see the attachment for the details' as body
from tblConfig
Pivot ( MAX(cValue) for cKey in (WorkProjectionReportTime,WorkProjectionReportToMailAlias) ) as xyz

So by query I get all the required fields, Email To, Time, report parameters.

I want to use the time parameter to schedule report.
e.g. if time is 9:30 the report should be mailed at 9:30 AM etc.
I want to achieve this from SQL or database front and not from C#. How to achieve this?

Combined with a scheduling table suggested above, you can use the following to send a report via TSQL, using @report_path as your parameter:

SELECT 'exec ReportServer.dbo.AddEvent @EventType=''TimedSubscription'', 
             @EventData=''' + CONVERT(VARCHAR(max), rs.SubscriptionID) + ''''
FROM   ReportServer.dbo.Catalog c,
       ReportServer.dbo.ReportSchedule rs,
       ReportServer.dbo.Schedule s
WHERE      rs.ReportID = c.ItemID
       AND rs.ScheduleID = s.ScheduleID
       AND c.path = @report_path
       AND s.RecurrenceType = 1 -- only the ones with the regular scheduling disabled
