Class RemoveEmptyDeleteRuleSet


  • public final class RemoveEmptyDeleteRuleSet
    extends Object
    If the predicate for a delete is optimized to false, the target table scan of the delete will be replaced with an empty values node. This type of plan cannot be executed and is meaningless anyway, so we replace the entire thing with a values node.
