In SQL Server 2005 Express, the result is below
SELECT 100 / 15 --Result 6
But I wanna get approximate value 7 (like using calculator)
100 / 15 = 6.6666..
How to make it in SQL Server?
You have to use decimal numbers e.g. 100 / 15.0. If you use integers the result is interpreted as an integer and truncated to the largest integer that is smaller than or equal to the result.
