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"."Sample".Products_table = "CData"."Sample".Products.metadata.tables["\"CData\".\"Sample\".Products"]

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"."Sample".Products_table.insert(), {"Id": "Jon Doe", "Name": "John"})

Update

The following example modifies an existing record in the table:

session.execute("CData"."Sample".Products_table.update().where("CData"."Sample".Products_table.c.Id == "1").values(Id="Jon Doe", Name="John"))

Delete

The following example removes an existing record from the table:

session.execute("CData"."Sample".Products_table.delete().where("CData"."Sample".Products_table.c.Id == "1"))
