Hi!
I have model with some field: person_id - Integer, service_id -
Integer, datetime - DateTime (timestamp) and some other.
How can I get all _LATEST BY datetime field_ services for person_id =
130960 ??
I have to get only:
2 | 2007-12-25 16:15:20.006126+02
3 | 2007-12-25 16:15:20.006126+02
4 | 2007-12-25 16:15:20.006126+02
75 | 2007-12-25 16:15:20.006126+02
103 | 2007-12-25 16:15:20.006126+02
rows.
Thank you!
eps=> SELECT service_id, datetime FROM
organizations_organizationdatabase WHERE person_id = 130960 ORDER BY
datetime DESC, service_id;
service_id | datetime
