  1. mysql> select hex(ipv6_string_to_num('1111::ffff'));
  2. +---------------------------------------+
  3. | hex(ipv6_string_to_num('1111::ffff')) |
  4. +---------------------------------------+
  5. | 1111000000000000000000000000FFFF      |
  6. +---------------------------------------+
  7. 1 row in set (0.02 sec)
  9. mysql> select hex(ipv6_string_to_num('192.168.0.1'));
  10. +----------------------------------------+
  11. | hex(ipv6_string_to_num('192.168.0.1')) |
  12. +----------------------------------------+

  15. 1 row in set (0.02 sec)
  17. mysql> select hex(ipv6_string_to_num('notaaddress'));
  18. ERROR 1105 (HY000): errCode = 2, detailMessage = (172.17.0.2)[CANCELLED][E33] Invalid IPv6 value
  20. mysql> select addr_src, hex(ipv6_string_to_num(addr_src)) from ipv4_string_test where addr_src is null;
  21. ERROR 1105 (HY000): errCode = 2, detailMessage = (172.17.0.2)[CANCELLED][E33] Null Input, you may consider convert it to a valid default IPv6 value like '::' first
