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(Accounts).order_by(Accounts.AnnualRevenue)
for instance in rs:
	print("AccountId: ", instance.AccountId)
	print("accountid: ", instance.accountid)
	print("Name: ", instance.Name)
	print("---------")

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

rs = session.execute(Accounts_table.select().order_by(Accounts_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(Accounts.AccountId).label("CustomCount"), Accounts.accountid).group_by(Accounts.accountid)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("accountid: ", instance.accountid)
	print("---------")

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

rs = session.execute(Accounts_table.select().with_only_columns([func.count(Accounts_table.c.AccountId).label("CustomCount"), Accounts_table.c.accountid]).group_by(Accounts_table.c.accountid))
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(Accounts).limit(25).offset(100)
for instance in rs:
	print("AccountId: ", instance.AccountId)
	print("accountid: ", instance.accountid)
	print("Name: ", instance.Name)
	print("---------")

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

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