> created (i.e. segment still has some records present)
> {code:sql}
> INSERT INTO testorders18 VALUES (11,'FAILURE', 125.15, DATE'2019-05-17'),
> (12,'SUCCESS', 135.12, DATE'2019-05-20'),(13,'1FAILURE', 125.15,
> DATE'2019-05-17'), (14,'SUCCESS', 135.12, DATE'2019-05-20');

> WHERE orderstatus= 'FAILURE');
