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(OEInvoices).order_by(OEInvoices.AnnualRevenue)
for instance in rs:
	print("Id: ", instance.Id)
	print("InvoiceUniquifier: ", instance.InvoiceUniquifier)
	print("ApprovedLimit: ", instance.ApprovedLimit)
	print("---------")

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

rs = session.execute(OEInvoices_table.select().order_by(OEInvoices_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(OEInvoices.Id).label("CustomCount"), OEInvoices.InvoiceUniquifier).group_by(OEInvoices.InvoiceUniquifier)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("InvoiceUniquifier: ", instance.InvoiceUniquifier)
	print("---------")

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

rs = session.execute(OEInvoices_table.select().with_only_columns([func.count(OEInvoices_table.c.Id).label("CustomCount"), OEInvoices_table.c.InvoiceUniquifier]).group_by(OEInvoices_table.c.InvoiceUniquifier))
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(OEInvoices).limit(25).offset(100)
for instance in rs:
	print("Id: ", instance.Id)
	print("InvoiceUniquifier: ", instance.InvoiceUniquifier)
	print("ApprovedLimit: ", instance.ApprovedLimit)
	print("---------")

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

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