Solution 1

did you try this

SQL

select Sum(case duration when 'Half Day' then '.5' when 'Full Day' then '1' when '"Hour*"' then dbo.GetNumbers(duration) else dbo.GetNumbers(duration) end) as DURATION from tbl_leave

other wise use this

SQL

select sum(cast(duration as float)) from (
select case duration when 'Half Day' then '.5' when 'Full Day' then '1' when '"Hour*"' then dbo.GetNumbers(duration) else dbo.GetNumbers(duration) end as DURATION from tbl_leave) as LeaveDuration

both of these should work.

Both of this will not work

pankajupadhyay29 7-Mar-11 4:47am

is some error there?

kishore Rajendran 7-Mar-11 4:47am

sum(duration) at first wont work because,duration is a VARCHAR field consisting of both full text like 'kishore' and half text like'kish123' and '12345' etc

your output is numeric use that as numeric value this will work.

pankajupadhyay29 7-Mar-11 4:59am

what values you r getting by your query are numeric for that you can change query like this sum(cast(duration as float)) i made the changes in second query in solution check that.
