I have an sql view only of the data which I import.
the data comes as
I want to Time2 -Time1
then I want to compare Time2 - Time1 (in Minutes) from the Expected Duration - so [Expected Duration] - (Time2 - Time1)
I have used the following statements in load to delete the M in 430 M:
Keepchar(ScheduledDuration,'1234567890') as SchedDurationMins, this actually gives me the number 430
To get the difference from Time2 - Time 1 I uses this when loaded
(time(Time2) - time(Time)) as DurationDiff, (however DurationDiff comes as a 0.226389 which I can then multiply by 24 *60 = 326
and it worked!!!
so just asking for helped worked - thank you all
