SQL：将一列从一个表移动到另一个表

Question

我有SQL代码，可为数据库表中的每一行添加一个默认值的新列。

我还需要它同时从另一个表中删除同一列，而且我不确定语法。

  public MainPage()
        {
  _originalHeight = ApplicationView.GetForCurrentView().VisibleBounds.Height;

            InputPane.GetForCurrentView().Showing += MainPage_Showing;
            InputPane.GetForCurrentView().Hiding += MainPage_Hiding;
        }

        private double _originalHeight;


        private void MainPage_Hiding(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            this.Height = _originalHeight;
            this.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Stretch;


        }

        private async void MainPage_Showing(InputPane sender, InputPaneVisibilityEventArgs args)
        {
            this.Height = _originalHeight - args.OccludedRect.Height;
            this.VerticalAlignment = Windows.UI.Xaml.VerticalAlignment.Top;
            await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
            {
                var parentScrollViewer = FindParent<ScrollViewer>(this);
                parentScrollViewer.VerticalScrollMode = ScrollMode.Disabled;

            });

        }
    }

在<***>点，我想要添加代码，无论该表的值是什么，该代码将从表create procedure remove_a_column() begin IF ( *some given condition* ) = 0 THEN ALTER TABLE static.new_table ADD COLUMN column_to_move smallint(6) DEFAULT 2, ADD FOREIGN KEY (column_to_move) REFERENCES static.other_table(pk); <***> END if; end 中删除列column_to_move。
