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:

WorkItems_table = WorkItems.metadata.tables["WorkItems"]

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(WorkItems_table.insert(), {"Id": "Jon Doe", "BuildNumber": "John"})

Update

The following example modifies an existing record in the table:

session.execute(WorkItems_table.update().where(WorkItems_table.c.Id == "2").values(Id="Jon Doe", BuildNumber="John"))

Delete

The following example removes an existing record from the table:

session.execute(WorkItems_table.delete().where(WorkItems_table.c.Id == "2"))
