Assuming the view definition (the SQL statement) is still valid after the structure change(s), the way I do it is to retrieve the query text for the view using DBGETPROP('nameofview','VIEW','SQL') and place it into a character variable. I then DELETE VIEW nameofview and replace it by issuing a CREATE SQL VIEW command using the retrieve view definition and macro expansion. If you don't want the obsolete view in the DBC just PACK DATABASE.
