Question

I have a table that contains two types in information one called Number_Of_Calls and another called Number_Of_Answered.

Now in my application I want to get how many percentage the Number_of_answered are of the Number_of_calls and I figured that calculating within the database would be the best way to do it.

However I don’t know how to calculate within SQL

So far I have:

Select Number_Of_Calls,
       Number_of_answered 
  from table 
 Where Date BETWEEN '2012-09-10' AND '2012-09-11'

Answer 1

select 
Number_of_Calls,
Number_of_Answered,
((Number_of_answered/Number_Of_Calls)*100) as answer_percent,
Date
from table Where Date BETWEEN '2012-09-10' AND '2012-09-11'
