Documentation

Definition

If this indicator is set, methods for loading persistent objects using a query are generated in the class actor.

Note that when this indicator is set, dynamic access (SELECT statement with dynamic WHERE condition) to persistent objects in this class is possible. This can lead to a security problem if entries on the user interface are transmitted directly without a query check.

Also read Note 1464130.

Use

Using the additional method

• IF_OS_CA_PERSISTENCY~GET_PERSISTENT_BY_QUERY

multiple persistent objects can be loaded with a method call (and a SELECT statement) into the main memory.

The number of objects to be loaded is specified in a query.

Dependencies

The Multiple Access indicator must also be set.

This indicator cannot be changed; one of the following methods has been changed:

• MAP_LOAD_FROM_DATABASE
• MAP_LOAD_FROM_DATABASE_KEY
• MAP_LOAD_FROM_DATABASE_GUID
