Ignore the SQL let Analytics handle that for you, the key here is to get your model correct.
You need a Time Dimension (ie. a table full of calendar dates) which you join to your Fact table date columns in the Physical layer.
In the logical layer fact table you should have two columns #Open and # Closed - these will be based on a case condition sum aggregate ie.
No. Open
CASE WHEN closed_date IS NULL THEN 1
ELSE 0
END
No. Closed
CASE WHEN closed_date IS NOT NULL THEN 1
ELSE 0
END
If you then make sure you join your Time Dimension (create an alias for each instance) to the open and closed dates you'll be able to have a count of the items closed by Year/Month/Week/Date etc...
