All Implemented Interfaces:

FarragoSessionDdlStmt

public class DdlDropLabelStmt
extends DdlDropStmt

DdlDropLabelStmt extends DdlDropStmt to remove obsolete label statistics. Repository design constraints related to upgrade prevent the statistics from being associated with the label itself. They are instead associated implicitly via time stamps. Therefore, drop rules are insufficient to trigger the necessary deletions. Avoid this pattern whenever possible!
