void AlterTableHandler::InsertFieldAction::simplifyActions (  ActionDictDict &  fieldActions  )  [virtual]

Legend: A,B==fields, P==property, [....]==action, (..,..,..) group of actions, <...> internal operation. Case 1: there are "change property" actions after the Insert action. -> change the properties in the Insert action itself and remove the "change property" actions. Examples: [Insert A] && [rename A to B] => [Insert B] [Insert A] && [change property P in field A] => [Insert A with P altered] Comment: we need to do this reduction because otherwise we'd need to do psyhical altering right after [Insert A] if [rename A to B] follows.
