SQL

select sum(RecommendToFriend)*100.0/count(RecommendToFriend) from CompanyReviews where IsRss=0 and cid=98

Nice solution! Here 100.0 is actually doing the upcast into a decimal value hence we're getting the output. :)

Solution 2

Try this:

SQL

SELECT cast(SUM(RecommendToFriend) AS decimal(10,2)) / COUNT(RecommendToFriend)*100
FROM companyreviews
