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:

Applications_table = Applications.metadata.tables["Applications"]

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(Applications_table.insert(), {"Sid": "MyApp1", "Name": "MyApp2"})

Update

The following example modifies an existing record in the table:

session.execute(Applications_table.update().where(Applications_table.c.Sid == "AP5ddf534702934bd3a446d293e8cdeb1f").values(Sid="MyApp1", Name="MyApp2"))

Delete

The following example removes an existing record from the table:

session.execute(Applications_table.delete().where(Applications_table.c.Sid == "AP5ddf534702934bd3a446d293e8cdeb1f"))
