I am not able to execute this query getting

ORA-00933: SQL command not properly ended
00933. 00000 – “SQL command not properly ended”

select count(user_id) 
from t_user 
where user_id = 2699478, object_id = 1329 
  and user_id not in
      (SELECT owner_user_id FROM t_obj where actual_id = 17447);  

Answer 1

You have to replace the comma , between the two conditions user_id=2699478 ,object_id=1329 with a proper conditional operators, and use parentheses to express them the way you want, like this:

SELECT COUNT(user_id) 
FROM t_user 
WHERE user_id = 2699478 
  AND object_id = 1329 
  AND user_id NOT IN
    (
        SELECT owner_user_id 
        FROM t_obj 
        WHERE actual_id = 17447
    )
