Stored Procedure in SQL Server 2008

Hello Experts,

I'm having trouble in writing a procedure to calculate "Work Time" for each ticket that is resolved in Help Desk environment. This work time should not calculate the time when a ticket is in "Pending" status.

This is the table structure with the data

TicketNo Status Datetime
TK123 TicketOpen 03/22/2011 7:00AM
TK123 To - Pending 03/22/2011 8:00AM
TK123 To - Open 03/22/2011 9:30AM
TK123 To-Pending 03/22/2011 10:00AM
TK123 To-Open 03/22/2011 10:45AM
TK123 To-Closure 03/22/2011 11:30AM

So actual work time should be 2 hours and 15 Minutes excluding Pending Hours ( Time when the ticket went to "To-Pending" and came out to "To-Open" status) which is 1 Hour and 15 Minutes.

How can I write a Procedure to do this calculate? Please assist.

Thank you very much

This should do and use it in a procedure if required:

select TicketNo, cast(cast(135/60 as varchar(10)) + ':' + cast(135%60 as varchar(10)) as time)
FROM 
(
select t1.TicketNo, t1.Status old_status, t2.Status new_status, DATEDIFF(mi, t1.Datetime, t2.Datetime) time_value
from ur_table_name t1
left join ur_table_name t2 on t1.TicketNo = t2.TicketNo and t1.rnum = t2.rnum - 1
Where t1.Status <> 'Pending' ) temp
GROUP BY TicketNo

-- Tested with your sample input

;with cte as (
SELECT TicketNo, Status, Datetime, ROW_NUMBER() over ( PARTITION BY TicketNo order by Datetime) rnum
FROM (
SELECT 'TK123' TicketNo, 'Open' Status,  cast('2011-03-22 7:00:00' as datetime) Datetime
union all
SELECT 'TK123', 'Pending',  cast('2011-03-22 8:00:00' as datetime)
union all
SELECT 'TK123', 'Open',  cast('2011-03-22 9:30:00' as datetime)
union all
SELECT 'TK123', 'Pending',  cast('2011-03-22 10:00:00' as datetime)
union all
SELECT 'TK123', 'Open',  cast('2011-03-22 10:45:00' as datetime)
union all
SELECT 'TK123', 'Closure',  cast('2011-03-22 11:30:00' as datetime)
)temp
)
select TicketNo, cast(cast(135/60 as varchar(10)) + ':' + cast(135%60 as varchar(10)) as time)
FROM 
(
select t1.TicketNo, t1.Status old_status, t2.Status new_status, DATEDIFF(mi, t1.Datetime, t2.Datetime) time_value
from cte t1
left join cte t2 on t1.TicketNo = t2.TicketNo and t1.rnum = t2.rnum - 1
Where t1.Status <> 'Pending' ) temp
GROUP BY TicketNo
