does not take the most recent timestamp when grouping :(
mysql SELECT DISTINCT Destination, SentDate FROM OutboundMessages WHERE
UserID='2
Hi all,
I am writing a PHP web page that displays some statistics based on
information in a database.
The database has a table (stats) with three fields:
ID, Sender, Text, UserID, Timestamp
I have set it up so that I get basic statistics with the following query:
SELECT Text, Count(*) FROM
or a full
hour).
The reason I want this kind of grouping is that if a person hits the
page
constantly for 5 minutes I don't want that to push other relevant IPs
down
the listing. Here's what I have to actually select the data from the
database.
SELECT tblVisitorHits.vIP, tblVisitorHits.vDateTime
try GROUP BY (UNIX_TIMESTAMP(tVH.vDateTime) -
MOD(UNIX_TIMESTAMP(tVH.vDateTime, 300)))

Ok here's what I trying to do. I am trying to design a little browser/ip
tracking page

I haven't succeeded in being able to group by time. My timestamp field
is -mm-dd hh:mm:ss. What I would like is have a query that will
enable me to be to group on events say every 5 minutes.
I've played around with using time_to_sec(timestamp) to convert all the
times to seconds and then

I've played around with using time_to_sec(timestamp)
of grouping on a primary table? I tried selecting a
MAX on the timestamp field, in the hope that somehow the resolution of that
maximum would leave the other fields in the record sticky to the position
that the maximum was found... with no success...
I really would like to avoid changing the structure
