INSERT INTO timecrunch.dbo.intervals (IntervalID, Duration) SELECT ixInterval, DATEDIFF(hour, dtStart, dtEnd) FROM fogbugz.dbo.TimeInterval WHERE dtEnd

INSERT INTO timecrunch.dbo.intervals (IntervalID, Duration) 
SELECT ixInterval, DATEDIFF(hour, dtStart, dtEnd) FROM fogbugz.dbo.TimeInterval
WHERE dtEnd is not NULL

IntervalID is an int, Duration is a float

I am trying to put all the hourly durations into the Duration column… I assume that even if it is less than an hour it will use a fraction which is why I put a float?

Help.

PS: It’s running fine no errors, but after it’s done the intervals table is still empty… I know the data is in the TimeInterval table though…

    I’m not sure why your data is not showing up, but DATEDIFF is not going to return a float. To get a float, you’ll probably want to use a smaller unit of time and divide by the number of your units per minute. Example:

    DATEDIFF(second, dtStart, dtEnd) / (3600.0)
