It's hard to phrase the question in a line of title, so let me rephrase it with an example.
I have a table order with fields order_id, order_date, etc. I want to select all orders that were placed in March, April and May in all years. So records with order_date of 03-MAR-09 and 18-MAY-13, etc. should all be selected.
Is there a date function in Oracle that provides such functionality?
