SUM(tablename/60) How to implement this?

Question

This is one line from my stored procedure. My table field hoursworked is storing minutes. How to store it by dividing it to 60.

(select 
    SUM(ISNULL(hoursworked,0)) 
 from 
    UserTime 
 where 
    userid = @employeeid 
    and convert(varchar(100),checkin,106) = convert(varchar(100),@Startdate,106) 
    and loginstatus= 'Out') 


hoursworked as int

how can I implement this

SUM(ISNULL(hoursworked/60,0))

Answer 1

What you probably got is 0. You should do the sum() first:

coalesce(sum(hoursworked)/60, 0)

The problem is that SQL Server does integer division, so any value less than 60 (and greater than or equal to 0) will result in 0. You might really want:

coalesce(sum(hoursworked)/60.0, 0)
