Selecting data from Months prior to sysdate

Question

How about if you need to pick the last 3 months prior to sysdate?

For example:

SQL

variable rundate varchar2(15);
execute :rundate :=to_char(sysdate);

variable Month1 varchar2(15);
execute :Month1 :=add_months(:rundate,-3);

But I only want orders in month vs. since exact date. If today is Mar 23, 2013 and I want previous month's order data, I don't want data from Feb 23rd to now. I just want Feb-13 orders.

How would you do that?

Thanks,
Adam

If you want to fetch data only from Feb-13, you need to find first and last day of February, then use it in SELECT statement.
