If your database object goes out of scope, the database is closed. This means you are typically going to want your database object be somewhat global to your app. A common technique is to have an iOSSQLiteDatabase property on the App object that you refer throughout your app as App.DB.


iOSSQLiteDatabase does an auto-commit after each SQL command if you do not manually start a transaction. You can start a transaction using this command:


When the transaction is complete, you commit your changes with this command:


You can cancel a transaction by calling rollback with this command:
