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(AccountCollection).order_by(AccountCollection.AnnualRevenue)
for instance in rs:
	print("ObjectID: ", instance.ObjectID)
	print("ObjectID: ", instance.ObjectID)
	print("AccountName: ", instance.AccountName)
	print("---------")

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

rs = session.execute(AccountCollection_table.select().order_by(AccountCollection_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(AccountCollection.ObjectID).label("CustomCount"), AccountCollection.ObjectID).group_by(AccountCollection.ObjectID)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("ObjectID: ", instance.ObjectID)
	print("---------")

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

rs = session.execute(AccountCollection_table.select().with_only_columns([func.count(AccountCollection_table.c.ObjectID).label("CustomCount"), AccountCollection_table.c.ObjectID]).group_by(AccountCollection_table.c.ObjectID))
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(AccountCollection).limit(25).offset(100)
for instance in rs:
	print("ObjectID: ", instance.ObjectID)
	print("ObjectID: ", instance.ObjectID)
	print("AccountName: ", instance.AccountName)
	print("---------")

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

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