IMetabaseUpdateUserEvents.OnAskReflectRights

Syntax

OnAskReflectRights(Var Cancel: Boolean);

Cancel - parameter that determines whether a request to update access permissions for objects on DBMS level is displayed.

The False value is passed by default, a request to update access permissions for objects on DBMS level is displayed.

If the True value is passed as a parameter value, the dialog box does not open, the permissions will be updated only on the platform level.

The OnAskReflectRights method implements an event that occurs before updating permissions for objects.

This example is a template for update unit. On applying of update that contains this unit the following is checked:

If update contains an update flag with the Ver identifier, a value "1.1" is assigned to this flag. Only the objects, for which an update condition equals to "Ver=1.1", are updated.
On data integrity violation the update of the whole object is skipped.
Permissions for objects, for which it is necessary, will be updated only on the platform level.
In update, the elements that delete repository objects are skipped.
