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(MARA).order_by(MARA.AnnualRevenue)
for instance in rs:
	print("Id: ", instance.Id)
	print("MANDT: ", instance.MANDT)
	print("MATNR: ", instance.MATNR)
	print("---------")

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

rs = session.execute(MARA_table.select().order_by(MARA_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(MARA.Id).label("CustomCount"), MARA.MANDT).group_by(MARA.MANDT)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("MANDT: ", instance.MANDT)
	print("---------")

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

rs = session.execute(MARA_table.select().with_only_columns([func.count(MARA_table.c.Id).label("CustomCount"), MARA_table.c.MANDT]).group_by(MARA_table.c.MANDT))
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(MARA).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("MANDT: ", instance.MANDT)
	print("MATNR: ", instance.MATNR)
	print("---------")

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

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