   ## Proposed changes
   ```
   select to_base64(aes_encrypt(column,'F3229A0B371ED2D9441B830D21A390C3', 
'0123456789'));
   In most case of user, the second and third argument are const literal.
   so handle the special case.
   
   mysql [test]>select count(aes_encrypt(a, 'seed1seed2seed3','0123456789')) 
from json_table_2;
   +-----------------------------------------------------------+
   | count(aes_encrypt(a, '***', '0123456789', 'AES_256_CBC')) |
   +-----------------------------------------------------------+
   |                                                  10000001 |
   +-----------------------------------------------------------+
   1 row in set (5.20 sec)
