SQL Divide by Two Count()

Question

I have the following query, which is trying to figure out the percentage of a certain product compared to the total number of products. IE: [Product Count] / [Total Products

Answer 1

Cast as something with decimal precision, not Integer. A float or real.

select cast(distinctCount as real)/cast(totalCount as real) * 100.00
   , distinctCount
   , totalCount
from (
 select count(distinct id) as distinctCount
  , count(id) as totalCount
  from Table) as aggregatedTable
