    Description

      In the ORACLE-Mode there is a problem with subtract / add from dates to sysdate

      e.g. in Oracle

      select sysdate - 7 from dual;

      I get the value, when today is the 02.07.2019:

      25.06.19 16:25:28

      When I try this in MariaDB

      select sysdate() -7;

      I get the text/number

      +----------------+
      		 
      | sysdate() -7   |
      		 
      +----------------+
      		 
      | 20190702162697 |
      		 
      +----------------+
      		 
      1 row in set (0.001 sec)

      correct is

      +---------------------+
      		 
      | sysdate() -7        |
      		 
      +---------------------+
      		 
      | 2019-06-25 16:27:29 |
      		 
      +---------------------+
      		 
      1 row in set (0.001 sec)

      The reason is that in Oracle subtractions the day is subtracted and not then seconds.
