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 below example sorts by a specified column using the session object's query() method.

rs = session.query([informix].Books).order_by([informix].Books.Price)
for instance in rs:
	print("Id: ", instance.Id)
	print("Id: ", instance.Id)
	print("Author: ", instance.Author)
	print("---------")

Alternatively, you can perform an ORDER BY using the session object's execute() method.

rs = session.execute([informix].Books_table.select().order_by([informix].Books_table.c.Price))
for instance in rs:

GROUP BY

The below example groups records with a specified column using the session object's query() method.

rs = session.query(func.count([informix].Books.Id).label("CustomCount"), [informix].Books.Id).group_by([informix].Books.Id)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("Id: ", instance.Id)
	print("---------")

Alternatively, you can perform a GROUP BY using the session object's execute() method.

rs = session.execute([informix].Books_table.select().with_only_columns([func.count([informix].Books_table.c.Id).label("CustomCount"), [informix].Books_table.c.Id]).group_by([informix].Books_table.c.Id))
for instance in rs:

LIMIT and OFFSET

The below example skips the first 100 records and fetches the following 25 using the session object's query() method.

rs = session.query([informix].Books).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("Id: ", instance.Id)
	print("Author: ", instance.Author)
	print("---------")

Alternatively, you can set a LIMIT or OFFSET using the session object's execute() method.

rs = session.execute([informix].Books_table.select().limit(25).offset(100))
for instance in rs:
