      create table t1 (x int) engine=Aria with system versioning
      partition by system_time limit 1 auto;
       
      delimiter //;
      create procedure dowhile()
      begin
        declare i int default 1;
       
        while i <= 500 DO
          insert into t1 values (i);
          delete from t1 where x=i;
          set i = i + 1;
        end while;
      end//
      delimiter ;//
      call dowhile;
       
      drop procedure dowhile;
      drop table t1;
