Hi does anyone know if is possible to declaratively concatenate two
columns together which you can later do query's on.
E.g. if I wanted to compute a new column course_name made up of
CONCAT(course_code,course_name)
Base = declarative_base()
class Course(Base):
__tablename__ = 'Course'
Hey Royce,

One gotcha that I ran into here is that you cannot have both the component
columns and the composite column mapped at the same time, like you do in
your example.
