Question

In SQL Server 2008, I am running a report where I need to divide two columns (called Completes and Prescreens, whole integers), and then I go to Excel and get the Prescreens divided by the Completes, and turn that into a number with 2 decimal places, then convert that to a percentage. i.e. -> 0.34, then becomes 34%.

In SQL in know I probably can’t get the output as “34%” but at least I’d like it as 0.34 . So far I have:

cast((sq.Completes/sq.Screens ) as float ) as 'conv'

Completes are the smaller of numbers(usually 27, 38, etc), and Screens are bigger numbers(124, 276, etc.)

But this is outputting my column as all 0s . How do I make it show 0.34 , 0.84, etc

Answer 1

Try it like this:

select (cast(sq.Completes as float)/cast(sq.Screens as float)) as 'conv'

You can also do this to round the value:

select round((cast(sq.Completes as float)/cast(sq.Screens as float)),2) as 'conv'

And finally, this to show it visually as a percentage:

select cast(round((cast(sq.Completes as float) /
   cast(sq.Screens as float)),2) * 100 as varchar(25)) 
   + '%' as 'conv'
