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(AccountsPayable.AccountLedger).order_by(AccountsPayable.AccountLedger.AnnualRevenue)
for instance in rs:
	print("Id: ", instance.Id)
	print("DocumentNumber: ", instance.DocumentNumber)
	print("Amount: ", instance.Amount)
	print("---------")

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

rs = session.execute(AccountsPayable.AccountLedger_table.select().order_by(AccountsPayable.AccountLedger_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(AccountsPayable.AccountLedger.Id).label("CustomCount"), AccountsPayable.AccountLedger.DocumentNumber).group_by(AccountsPayable.AccountLedger.DocumentNumber)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("DocumentNumber: ", instance.DocumentNumber)
	print("---------")

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

rs = session.execute(AccountsPayable.AccountLedger_table.select().with_only_columns([func.count(AccountsPayable.AccountLedger_table.c.Id).label("CustomCount"), AccountsPayable.AccountLedger_table.c.DocumentNumber]).group_by(AccountsPayable.AccountLedger_table.c.DocumentNumber))
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(AccountsPayable.AccountLedger).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("DocumentNumber: ", instance.DocumentNumber)
	print("Amount: ", instance.Amount)
	print("---------")

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

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