Commands can be executed individually by the session with a call to "execute()".

Obtaining the Table Object

The query supplied to this method is constructed using the associated Table object of a mapped class. This Table object is obtained from the mapped class's metadata field, as below:

[CData].[Entities].Customers_table = [CData].[Entities].Customers.metadata.tables["[CData].[Entities].Customers"]

Once the table object is obtained, the write operations are executed in the following ways. The queries are executed immediately without the need for a call to "commit()":

Insert

The following example adds a new record to the table:

session.execute([CData].[Entities].Customers_table.insert(), {"City": "Jon Deere", "CompanyName": "Caterpillar"})

Update

The following example modifies an existing record in the table:

session.execute([CData].[Entities].Customers_table.update().where([CData].[Entities].Customers_table.c._id == "22").values(City="Jon Deere", CompanyName="Caterpillar"))

Delete

The following example removes an existing record from the table:

session.execute([CData].[Entities].Customers_table.delete().where([CData].[Entities].Customers_table.c._id == "22"))
