To modify the properties of a column:

  1. Select a column name from the OpenEdge DB Structure view.
  2. Right-click, and choose Edit Column from the context menu. If you are connected to an OpenEdge database, Edit Column is also available on the OpenEdge Columns tab of the OpenEdge DB Details view.
  3. Enter changes in the Edit Columns dialog.
    Note: Generally you cannot change the data type of a column, but you can change an INTEGER data type to INT64. Once you change to INT64, you cannot change back to INTEGER from DB Navigator.
  4. Click Finish.
