    Description

      This script works fine:

      SET sql_mode='';
      		 
      SET optimizer_switch='';

      Now if I change sql_mode, the statement setting optimizer_switch starts to fail:

      SET sql_mode=EMPTY_STRING_IS_NULL;
      		 
      SET optimizer_switch='';


      ERROR 1231 (42000): Variable 'optimizer_switch' can't be set to the value of 'NULL'
