Set the TIB_Query.GetServerDefaults property to True and IBO will get the
DEFAULT constraints that are on the server. But, you can also set Required
to False for the appropriate fields, so that it's the server that assigns
the default values.

When you clear out the values they are not set to NULL, but just set as an
empty string. And, an empty string is NOT NULL.
