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(Traffic).order_by(Traffic.AnnualRevenue)
for instance in rs:
	print("Id: ", instance.Id)
	print("Browser: ", instance.Browser)
	print("DeviceCategory: ", instance.DeviceCategory)
	print("---------")

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

rs = session.execute(Traffic_table.select().order_by(Traffic_table.c.AnnualRevenue))
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(Traffic.Id).label("CustomCount"), Traffic.Browser).group_by(Traffic.Browser)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("Browser: ", instance.Browser)
	print("---------")

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

rs = session.execute(Traffic_table.select().with_only_columns([func.count(Traffic_table.c.Id).label("CustomCount"), Traffic_table.c.Browser]).group_by(Traffic_table.c.Browser))
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(Traffic).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("Browser: ", instance.Browser)
	print("DeviceCategory: ", instance.DeviceCategory)
	print("---------")

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

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