This PR allows SQL to set
DEFAULT NULL
which currently isn't supported because the code is built asDEFAULT
(empty value instead of NULL).It also adds support for updating a field to
NULL
that isNOT NULL
and doesn't have aDEFAULT
value.The result of the update should be an empty value ('' for text and 0 for numbers).
