Select data from date range between two dates

Question

I have a database called Product Sales that contains the following data.

Product_ID | Sold_by | Qty | From_date  | To_date
-----------+---------+-----+------------+-----------
3          | 12      | 7   | 2013-01-05 | 2013-01-07
6          | 22      | 14  | 2013-01-06 | 2013-01-10
8          | 11      | 9   | 2013-02-05 | 2013-02-11

Now what is the query if I want to select sales data between two dates from a date range?

For example, I want to select sales data from 2013-01-03 to 2013-01-09.
