    Description

      Note: it's all the same in Percona server, but I won't file a bug for Percona, because there the whole 'profiling' logic is deprecated, as it is in MySQL 5.6. In MariaDB 10.1 it's still not deprecated, so it should work.

      Session profiling is OFF

      MariaDB [test]> set profiling = 0;
      Query OK, 0 rows affected (0.01 sec)
       
      MariaDB [test]> select 'without profiling';
      +-------------------+
      | without profiling |
      +-------------------+
      | without profiling |
      +-------------------+
      1 row in set (0.00 sec)
       
      MariaDB [test]> set statement profiling=1 for select 'with one-statement profiling';
      +------------------------------+
      | with one-statement profiling |
      +------------------------------+
      | with one-statement profiling |
      +------------------------------+
      1 row in set (0.00 sec)
       
      MariaDB [test]> show profiles;
      Empty set (0.00 sec)

      Session profiling is ON

      MariaDB [test]> set profiling = 1;
