http://www.leeladharan.com/sqlalchemy-query-with-or-and-like-common-filters

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 ANDfilter(User.name == ‘leela‘, User.fullname == ‘leela dharan‘)# or call filter()/filter_by() multiple timesfilter(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‘))
