I have data with a timestamp attribute and need to retrieve a hour-count-report.
Example:

12:10:15 - data1
12:11:10 - data2
13:18:10 - data3
13:38:21 - data4
13:43:00 - data5


the report should come like this:

12-13 | 2
13-14 | 3


Could anybody help me to make this hql query?
thanks!

Sorry for bothering! i´ve found the answer on chapter 15. I haven't tested yet, but I'm quite sure it'll work!
thanks anyway.
