Hint Details:

<pclass="hint_description">The following calculation returns 0:

select
23/26*100

Sybase is seeing two integers being divided and returning an integer as an answer. To get the percent calculation required:

select
23.0/26.0*100

As the following will not give the desired result:

select
count(*) as NumUnits,
sum(unitoccupied(unit.unitid)) as NumOcc,
NumOcc/NumUnits/100 as PercentOcc
from
unit join sizecodrate join sizecode

It needs to be:

select
cast(count(*) as NumUnits as float),
cast(sum(unitoccupied(unit.unitid)) as float) as NumOcc,
NumOcc/NumUnits/100 as PercentOcc
from
unit join sizecodrate join sizecode
