I see, thus, this definition:
Column('abc', Unicode(20), server_default='abc')
Column('adef', Numeric(12,3), server_default=text('1.5')),
is equivalent to this one:
Column('abc', Unicode(20), DefaultClause('abc'))
Column('def', Numeric(12,3),
Why don't you pass the params to session.query as a dictionary into
