在SQL中将分钟转换为小时和十进制

Question

I have been referring this solution Format minutes into hours and minutes as a decimal number in T-SQL

but what I want is the value after decimal should represent the correct fraction?

On converting 30 minutes to hours, this formula is incorrect

select 30/60+(30%60)/100.0 --0.30

where as the result should be:

select 30*0.0166667

Answer 1

You have to just divide minutes by 60 . you can use below query.

SELECT 30/60.0
