       Controls whether or not C character strings are filled with
       blanks as required by the SQL89 and ANSI/ISO SQL standards or
       if the null terminator is placed after the last data byte of
       the source string.

    o  [NO]FIXED_CDD_STRINGS (default: NOFIXED_CDD_STRINGS)

       Controls whether or not SQL treats C character strings from
       Oracle CDD/Repository record definitions as fixed-length
       character strings or C null-terminated strings.
