DateDiff years into decimals

datediff, sql-server-2008, t-sql

Solution

Try this instead.

DATEDIFF(dd, @EndDateTime, i.mat_exp_dte)/365.0

Dividing int with an int returns int. Divide with a decimal and you will get a decimal as a result.

Problem

I have two dates in which i would like to find the number of years between them, however i would need to show the value to two decimal places. I have tried the following but i always get a value returned of 0 as all of my dates do not cover a whole year: ``` DATEDIFF(yy, @EndDateTime, i.mat_exp_dte) ``` I have then tried finding the number of days between the two and then dividing it by 365, but this still returns 0: ``` DATEDIFF(dd, @EndDateTime, i.mat_exp_dte)/365 ``` Am confused now as to how to calculate this. Would i need to convert the DataDiff into a different data type?
