Updating Data

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].[Default].Customers_table = [CData].[Default].Customers.metadata.tables["[CData].[Default].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].[Default].Customers_table.insert(), {"City": "Jon Deere", "CompanyName": "RSSBus Inc."})
