Solution 2

Hello,

This is how I do it:

SQL

DECLARE @endTime   DATETIME = '18:00'
DECLARE @duration  DATETIME = '1:45'
SELECT CONVERT(TIME(0), ((@endTime - @duration)))

Solution 1

try this (tested on 2008 R2):

SQL

declare @d1 datetime='2010-01-01 01:45';
declare @d2 datetime='2010-01-01 18:00';

SELECT CONVERT(varchar,datediff(MI, @d1, @d2)/60)
    +':'+ CONVERT(varchar, datediff(MI, @d1, @d2)-60*(datediff(MI, @d1, @d2)/60))

SQL

select CAST((CAST(FLOOR(18.00) * 60 + FLOOR(100 * 18.00) % 100 AS INT)-CAST(FLOOR(1.45) * 60 + FLOOR(100 * 1.45) % 100 AS INT))/60 +
            (CAST(FLOOR(18.00) * 60 + FLOOR(100 * 18.00) % 100 AS INT)-CAST(FLOOR(1.45) * 60 + FLOOR(100 * 1.45) % 100 AS INT))%60 *0.01 AS DECIMAL(5,2))
