SQLAlchemy Core select where condition contains boolean expression `is False`

Question

How to use SQLAlchemy expression language to select columns with where condition to check boolean expression. example:

select([table]).\\
    where(and_(tabl         


        

Answer 1

According to the documentation, the way you should handle this is by using the true() or false() constants that you can import from SqlAlchemy. It would look like this:

from sqlalchemy import false

select([table]).\
    where(and_(table.c.col1 == 'abc',
               table.c.is_num == false() 
    ))

Hope this helps!
