How do I count the number of items that have been inserted at a given time interval in the DB?

All Columns have a timestamp from that I can get that information. I tried already this but I don't get it to work!!
if for example you want to group the number of occurences of a row by the hour part of the time stamp, try something like this (MySQL syntax):
select hour(TimeStamp) as interval, count(*) from data group by interval;
