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:

res_users_table = res_users.metadata.tables["res_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(res_users_table.insert(), {"name": "[email protected]", "email": "John"})

Update

The following example modifies an existing record in the table:

session.execute(res_users_table.update().where(res_users_table.c.id == "12").values(name="[email protected]", email="John"))

Delete

The following example removes an existing record from the table:

session.execute(res_users_table.delete().where(res_users_table.c.id == "12"))
