Question

I have a Table that looks like this

MAC-ADDRESS | ACCESSPOINT | TIMESTAMP

Data is pushed into the table by all the Accesspoints at 15 minutes intervals.

I want to run a query to tell me the MAC-Addresses that have appeared on more then one Accesspoint withtin a given datim range ?

Answer 1

select mac,count( distinct name) as occ from

(Select mac,name from maclist
where datim between “2011-07-08 00:00:00” and “2011-07-14 23:59:59”
group by name,mac order by mac)

as tmo group by mac having occ>1;

This worked for me
