      Description

      A valid SQL query is

      select nullif(count(distinct col1),0) from table1 ;

      now if I create this as a view with

      create view counts4 AS select nullif(count(distinct col1),0) from table1 ;

      and try to look at the view I get an error

      select * from counts4;
      /* SQL Error (1064): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '<cache>(count(distinct `testdb5`.`table1`.`col1`)),0) AS `nullif(count(distinct ' at line 1 */

      this exact same procedure works fine on mariadb 10.0.23
      and this bug may have something to do with https://lists.launchpad.net/maria-developers/msg09111.html

      I can't test it on 10.1.10 since windows wont allow me to downgrade and I cant uninstall.
      This (again) affects all kodi users that can't create db's anymore

      to recreate db

      CREATE DATABASE IF NOT EXISTS `testdb5` 
      USE `testdb5`;
       
      CREATE TABLE IF NOT EXISTS `table1` (
        `col1` varchar(50) DEFAULT NULL
      ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

      Thanks!
