Hello,
I got the two picutures attached from mycheckpoint's web graph.
They are showing the threads_connected have been increasing from 24th.

Hello list,
I want to get the counter for db-items by each day,so I wrote this sql:
select count(*) as dd from items group by updatetime;
But sorry "updatetime" is "datetime" type,not "date" type.Then I can't get the
correct result.
How can I do this?Thanks.
