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].[Administrators].Users_table = [CData].[Administrators].Users.metadata.tables["[CData].[Administrators].Users"]

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].[Administrators].Users_table.insert(), {"Username": "Jon Doe", "Email": "John"})

Update

The following example modifies an existing record in the table:

session.execute([CData].[Administrators].Users_table.update().where([CData].[Administrators].Users_table.c.Id == "39ef9b6f-5973-4701-bd19-7950d4b7d6e0").values(Username="Jon Doe", Email="John"))

Delete

The following example removes an existing record from the table:

session.execute([CData].[Administrators].Users_table.delete().where([CData].[Administrators].Users_table.c.Id == "39ef9b6f-5973-4701-bd19-7950d4b7d6e0"))
