Altering columns used in a computed column

Hi David,
That's interesting... is the script trying to drop the column 'Quantity'
or 'Price'? It seems like the error message doesn't have much to do with
changing the default of the Quantity or Price columns.

That makes sense. I suppose the problem is that SQL Compare didn't pick
up the dependencies on those columns.
