Ah ic. I think that in a situation where you are passing an empty string to a
numerical field with no default, either SQL must throw an error, or else insert
what amounts to nothing in a numeric column.
I think the nature of sqLite is that Instead of tossing an error it puts 0 in
the column. Y

I absolutely agree that default values should be defined in the database
but it wouldn't help in this case since he wants the default to be either
NULL or empty and LC has taken it upon itself to decide it knows better

Yes, it causes a headache, you're right. You would have to build the
