END
CLOSE FrmTicket
DEALLOCATE FrmTicket
return
end;


after creating this table inlined functions i have created views to get data from @tblOpentrf which is follows

ALTER VIEW [dbo].[OpenTRFView]
AS
SELECT [Req No], [Employee ID], [Employee Name], Designation, [Travel Purpose], Approver, [Booking Type], [Amount Payable to TA],
[Total Estimated Approved Amount], [Est Travel Cost], [Est L and B], [Est Incidental Cost], Zone, Location, Department, Status, [Cost Center],
[Travel from Date], [Travel to Date]
FROM dbpenTRF() AS OpenTRF_1

after that i have used following query to display in front end

Select OpenTRFView.[Req No][Req No],OpenTRFView.[Travel from Date][Travel from Date],OpenTRFView.[Travel to Date][Travel to Date],OpenTRFView.[Employee ID][Employee ID],OpenTRFView.[Employee Name][Employee Name],OpenTRFView.[Designation][Designation],OpenTRFView.[Travel Purpose][Travel Purpose],OpenTRFView.[Approver][Approver],OpenTRFView.[Booking Type][Booking Type],OpenTRFView.[Amount Payable to TA][Amount Payable to TA],OpenTRFView.[Total Estimated Approved Amount][Total Estimated Approved Amount],OpenTRFView.[Est Travel Cost][Est Travel Cost],OpenTRFView.[Est L and B][Est L and B],OpenTRFView.[Est Incidental Cost][Est Incidental Cost],OpenTRFView.[Zone][Zone],OpenTRFView.[Location][Location],OpenTRFView.[Department][Department],OpenTRFView.[Cost Center][Cost Center],OpenTRFView.[Status][Status] from OpenTRFView


My problem here is if there is huge number of records the query takes huge time to execute around one hour i need reduce this into 10 or 15 seconds kindly help
