I have two tables, one contains units one contains activity
I run this query ......
select unit.dialup_user, unit.address1, activity.dialup_user
from unit
LEFT JOIN activity ON
(unit.dialup_user = activity.dialup_user)
where !(activity.event_time_unix > (981990589 - (2* ( 24 * (60 *
60) ) ) ) ) && unit.status ="Active"
GROUP BY unit.id
What I am trying to do is select every unit that does not have an entry in
the activity table after a certain unix time.
Any help would be much appreciated
Here is the output from the explain command
table type possible_keys key key_len ref rows
Extra
----- ---- ------------- --- ------- --- ----
-----
unit ALL NULL NULL NULL NULL 840 where used; Using
temporary
activity ALL NULL NULL NULL NULL 29109 where used
(2 row(s) affected)
