Dear,

I have two Column Start & End both are Datetime data type.

The Data is

Start End
12:30 15:00

The Total min is 150
i used below query

DATEDIFF(mi, dbo.Trn_Daily3.Dr_TimeStart, dbo.Trn_Daily3.Dr_TimeEnd)

Its giving correct result=150

But when i convert into hour

DATEDIFF(mi, dbo.Trn_Daily3.Dr_TimeStart, dbo.Trn_Daily3.Dr_TimeEnd)/60

then result is 2 but actual 150/60=2.5

How to do it.

Please help on this

Thanks
Basit.

Solution 1

Did you try to divide by a non integer ?
Try to replace

SQL

DATEDIFF(mi, dbo.Trn_Daily3.Dr_TimeStart, dbo.Trn_Daily3.Dr_TimeEnd)/60

with

SQL

DATEDIFF(mi, dbo.Trn_Daily3.Dr_TimeStart, dbo.Trn_Daily3.Dr_TimeEnd)/60.0

as for many languages like C, C++, C#
a divide of integers result in an integer.

Solution 3

Try

SQL

DATEDIFF(mi, dbo.Trn_Daily3.Dr_TimeStart, dbo.Trn_Daily3.Dr_TimeEnd)/60.0

See "/ (Divide) (Transact-SQL)"[^]
