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(Sheet).order_by(Sheet.AnnualRevenue)
for instance in rs:
	print("RowId: ", instance.RowId)
	print("RowId: ", instance.RowId)
	print("LastName: ", instance.LastName)
	print("---------")

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

rs = session.execute(Sheet_table.select().order_by(Sheet_table.c.AnnualRevenue))
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(Sheet.RowId).label("CustomCount"), Sheet.RowId).group_by(Sheet.RowId)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("RowId: ", instance.RowId)
	print("---------")

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

rs = session.execute(Sheet_table.select().with_only_columns([func.count(Sheet_table.c.RowId).label("CustomCount"), Sheet_table.c.RowId]).group_by(Sheet_table.c.RowId))
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(Sheet).limit(25).offset(100)
for instance in rs:
	print("RowId: ", instance.RowId)
	print("RowId: ", instance.RowId)
	print("LastName: ", instance.LastName)
	print("---------")

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

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