Modifying 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:
Cards_table = Cards.metadata.tables["Cards"]
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(Cards_table.insert(), {"Name": "Jon Doe", "ListId": "614060a64bf2e765da7bd43f"})
Update
The following example modifies an existing record in the table:
session.execute(Cards_table.update().where(Cards_table.c.CardId == "5835594ee009411c6abdbfbd").values(Name="Jon Doe", ListId="614060a64bf2e765da7bd43f"))
Delete
The following example removes an existing record from the table:
session.execute(Cards_table.delete().where(Cards_table.c.CardId == "5835594ee009411c6abdbfbd"))
