I have a little issue with my SQLite query which I use in python. In my little test_table I got 4 columns: sys_id, aq, vq, off_id. If I search for example for off_id=7477310
SELECT * FROM test_db WHERE off_id="7477310"
I get results:
sys_id aq vq off_id 154803 50 40 7477310 153355 30 30 7477310 153455 50 40 7477310 163455 20 40 7477310
But I would also like a direct comparsion by this priority (vq,aq,sys_id) so I tought I use max
. So the goal is if one result has the highest vq it directly wins, if vq ar identicial with more than one row next is aq, if aq is higher direct win, and last is sys_id if vq and aq is the same sys_id the highest sys_id wins.
Any ideas?
Thanks a lot

Answer
It looks like you want order by
and limit
:
select * from test_db where off_id = '7477310' order by vq desc, aq desc, sys_id desc limit 1
