A username and/or password was expected on the command line.
  Null is being used

  Explanation:  In a DECLARE ALIAS statement the DEFAULT keyword
  was used in place of the actual username or password.  The
  necessary qualifiers were not provided in the compilation
  command line, so a null is being used.

  User Action:  Compile the module again and provide the necessary
  username and/or password qualifiers.  For SQL$MOD use
  /USERNAME=username /PASSWORD=password.  For SQL$PRE use
  /SQLOPTIONS=(USERNAME=username,PASSWORD=password).
