How to retrieve data based on month end dates

Hi guys

I need to get last 6 months of data grouped by month end dates....

I need to automate this query so that it always looks for date for last 6 months

How do I achieve this?

For ex my database has a base date starting from 01 July 2013. Its a daily level data for total connections...

I want my report to be like

Month_End Date   Total Connections

31 Jul 2013            200

31 Aug                  300

30 Sep                   500

...and so on

Appreciate all your help

Regards
