SQLAlchemy ORM also exposes support for other clauses in SQL, such as ORDER BY, GROUP BY, LIMIT, and OFFSET. All of these are supported by this connector:

ORDER BY

The following example sorts by a specified column using the session object's query() method:

rs = session.query(res_users).order_by(res_users.meeting_count)
for instance in rs:
	print("id: ", instance.id)
	print("name: ", instance.name)
	print("email: ", instance.email)
	print("---------")

You can also use the session object's execute() method perform an ORDER BY. For example:

rs = session.execute(res_users_table.select().order_by(res_users_table.c.meeting_count))
for instance in rs:

GROUP BY

The following example uses the session object's query() method to group records with a specified column:

rs = session.query(func.count(res_users.id).label("CustomCount"), res_users.name).group_by(res_users.name)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("name: ", instance.name)
	print("---------")

You can also use the session object's execute() method to perform a GROUP BY:

rs = session.execute(res_users_table.select().with_only_columns([func.count(res_users_table.c.id).label("CustomCount"), res_users_table.c.name]).group_by(res_users_table.c.name))
for instance in rs:

LIMIT and OFFSET

The following example uses the session object's query() method to skip the first 100 records and fetch the following 25:

rs = session.query(res_users).limit(25).offset(100)
for instance in rs:
	print("id: ", instance.id)
	print("name: ", instance.name)
	print("email: ", instance.email)
	print("---------")

You can also use the session object's execute() method to set a LIMIT or OFFSET:

rs = session.execute(res_users_table.select().limit(25).offset(100))
for instance in rs:
