If you use the database in a multi-threaded environment, you must always your statements in transactions. For read-only statements, you use DeferredTransaction and write statements you use ImmediateTransaction. If you mix read and write statements you have to use ImmediateTransaction. Don't use DeferredTransaction because it leads to undefined behavior.
