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(NorthwindOData).order_by(NorthwindOData.AnnualRevenue)
for instance in rs:
	print("Id: ", instance.Id)
	print("personal.name.first: ", instance.personal.name.first)
	print("personal.name.last: ", instance.personal.name.last)
	print("---------")

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

rs = session.execute(NorthwindOData_table.select().order_by(NorthwindOData_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(NorthwindOData.Id).label("CustomCount"), NorthwindOData.personal.name.first).group_by(NorthwindOData.personal.name.first)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("personal.name.first: ", instance.personal.name.first)
	print("---------")

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

rs = session.execute(NorthwindOData_table.select().with_only_columns([func.count(NorthwindOData_table.c.Id).label("CustomCount"), NorthwindOData_table.c.personal.name.first]).group_by(NorthwindOData_table.c.personal.name.first))
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(NorthwindOData).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("personal.name.first: ", instance.personal.name.first)
	print("personal.name.last: ", instance.personal.name.last)
	print("---------")

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

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