truncation error in sybase ?

hello experts,

I get truncation error when i try to do the following

set nocount on
declare @var1 int,
        @var2 int,
        @var3 numeric(10,2)
select @var1 = 5
select @var2 = 6

select @var3 = @var1/@var2

select @var3


I get a 0 in @var3 and a trucation error occured ..

basically i want to do a @var1/@var2 * 100 (to find out the % )

how can this be done ?

You need to convert @var1 to some more precise numeric type (eg. numeric(10,2) ) to get rid of 0 and convert whole expresion to the same type to get rid of truncation error:

select @var3 = convert(numeric(10,2),convert(numeric(10,2),@var1)/@var2)

Other way how to get rid of truncation error:

set arithabort numeric_truncation off
select @var3 = convert(numeric(10,2),@var1)/@var2
set arithabort numeric_truncation on

Even more simply:

select @var3 = 1.0*@var1/@var2

There is a hierarchy of datatypes. When the expression is just "@var1/@var2", Sybase sees only integers, and assumes you want integer division. By adding the 1.0 at the start of the expression, Sybase understands you're talking about numerics (as numerics take precedence over integers, so the entire expression is "promoted" to a numeric).
