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"."dbo".NorthwindProducts).order_by("CData"."dbo".NorthwindProducts.unitPrice)
for instance in rs:
	print("ProductId: ", instance.ProductId)
	print("ProductId: ", instance.ProductId)
	print("ProductName: ", instance.ProductName)
	print("---------")

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

rs = session.execute("CData"."dbo".NorthwindProducts_table.select().order_by("CData"."dbo".NorthwindProducts_table.c.unitPrice))
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"."dbo".NorthwindProducts.ProductId).label("CustomCount"), "CData"."dbo".NorthwindProducts.ProductId).group_by("CData"."dbo".NorthwindProducts.ProductId)
for instance in rs:
	print("Count: ", instance.CustomCount)
	print("ProductId: ", instance.ProductId)
	print("---------")

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

rs = session.execute("CData"."dbo".NorthwindProducts_table.select().with_only_columns([func.count("CData"."dbo".NorthwindProducts_table.c.ProductId).label("CustomCount"), "CData"."dbo".NorthwindProducts_table.c.ProductId]).group_by("CData"."dbo".NorthwindProducts_table.c.ProductId))
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"."dbo".NorthwindProducts).limit(25).offset(100)
for instance in rs:
	print("ProductId: ", instance.ProductId)
	print("ProductId: ", instance.ProductId)
	print("ProductName: ", instance.ProductName)
	print("---------")

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

rs = session.execute("CData"."dbo".NorthwindProducts_table.select().limit(25).offset(100))
for instance in rs:
