Some of the most common operators used in filter() method SQLAlchemy
equals:
query.filter(User.name == 'leela')
not equals:
query.filter(User.name != 'leela')
LIKE:
query.filter(User.name.like('%leela%'))
IN:
query.filter(User.name.in_(['leela', 'akshay', 'santanu']))
# works with query objects too:
query.filter(User.name.in_(session.query(User.name).filter(User.name.like('%santanu%'))))
NOT IN:
query.filter(~User.name.in_(['lee', 'sonal', 'akshay']))
IS NULL:
filter(User.name == None)
IS NOT NULL:
filter(User.name != None)
AND:
from sqlalchemy import and_
filter(and_(User.name == 'leela', User.fullname == 'leela dharan'))
#or, default without and_ method comma separated list of conditions are AND
filter(User.name == 'leela', User.fullname == 'leela dharan')
# or call filter()/filter_by() multiple times
filter(User.name == 'leela').filter(User.fullname == 'leela dharan')
OR:
from sqlalchemy import or_
filter(or_(User.name == 'leela', User.name == 'akshay'))
match:
query.filter(User.name.match('leela'))
