Логика оператора Postgres не работает?

Question

не могу за жизнь мне понять, почему им получать эту строку назад

order_id | job_name | memname |  status  | state 
----------+----------+---------+----------------+---------- 
0e4ba | pwd_test |   | Wait Condition | Deleted 

работает этот запрос

select order_id, job_name, memname, status, state 
from a150708002_ajob 
where order_time < '20150601' 
    and status != 'Ended OK' 
    or state != 'Deleted' 
    and order_time < '20150601'; 

общий результат:

em800=> select order_id, job_name, memname, status, state from a150708002_ajob where order_time < '20150601' and status != 'Ended OK' or state != 'Deleted' and order_time < '20150601'; 
order_id | job_name | memname |  status  | state 
----------+----------+---------+----------------+---------- 
0e4ba | pwd_test |   | Wait Condition | Deleted 
0eevd | DBPE220A |   | Wait Condition | Held 
0eeve | SHAW  |   | Wait Condition | Held 

Не уверен, что происходит ?

ОТВЕТ:

оказывается логик был прекрасен его только значение внутри клетки имело косую пробельные

ctmtest1-tctmsv80 [13] python del_jobs_main.py 20150625 150712 
select order_id, status, state from a150712002_ajob where order_time < '20150625' and not (status = 'Ended OK' or state = 'Deleted'); 
' order_id |  status  | state ' 
'----------+----------------+----------' 
' 0eeve | Wait Condition | Deleted ' 
' 0eevd | Wait Condition | Deleted ' 
'(2 rows)' 

так я только что добавил косую белого символа пробела на мой запрос. Спасибо, ребята :)

Answer 1

Недостающие некоторые скобки в государственной проверке:

select order_id, job_name, memname, status, state from a150708002_ajob 
where order_time < '20150601' and 
(status != 'Ended OK' or state != 'Deleted') and order_time < '20150601'; 

Скобки определяют, как OR оценивается.
