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([CData].[Entities].Customers).order_by([CData].[Entities].Customers.Balance)
for instance in rs:
	print("_id: ", instance._id)
	print("City: ", instance.City)
	print("CompanyName: ", instance.CompanyName)
	print("---------")

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

rs = session.execute([CData].[Entities].Customers_table.select().order_by([CData].[Entities].Customers_table.c.Balance))
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([CData].[Entities].Customers._id).label("CustomCount"), [CData].[Entities].Customers.City).group_by([CData].[Entities].Customers.City)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("City: ", instance.City)
	print("---------")

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

rs = session.execute([CData].[Entities].Customers_table.select().with_only_columns([func.count([CData].[Entities].Customers_table.c._id).label("CustomCount"), [CData].[Entities].Customers_table.c.City]).group_by([CData].[Entities].Customers_table.c.City))
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([CData].[Entities].Customers).limit(25).offset(100)
for instance in rs:
	print("_id: ", instance._id)
	print("City: ", instance.City)
	print("CompanyName: ", instance.CompanyName)
	print("---------")

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

rs = session.execute([CData].[Entities].Customers_table.select().limit(25).offset(100))
for instance in rs:
