Nonstandard syntax -- required keyword or clause omitted

  Explanation:  The syntax indicated is not included in the
  current ANSI and ISO standards for SQL.  The standard requires a
  clause or keyword which is optional in the SQL interface to
  Oracle Rdb.  You have omitted that clause or keyword.

  User Action:  If it is important to have only standard syntax in
  your program, you should remove this syntax.
