Question

I have a table(offer) with three columns, id, product_id and price.

offer
----- 
id (integer)   
product_id (integer)
price (decimal)

I wanted to fire a SQL query which will return the number of offers between a price range.
range should be like 0-1, 1-2, 2-3 etc

price_lower   price_upper    number_of_offers
-------------------------------------------------------------
0                     1            4
1                     2            1
2                     3            0
3                     4            6
4                     5            2
... etc

I did this to get the number of offers between 0 and 1

SELECT * FROM offer WHERE price BETWEEN 0 and 1;

What should be the query to get desired result.

Any sort of help will be appreciated. Thanks in advance.

While Checking all the answers. I have managed to write the query of course with your help.
As few of you suggested to create a new table to store offer range which i don’t want to do.

So, here is the SQL query what i wanted:

SELECT price as price_lower, (price + 1) as price_upper, (SELECT count(*) from offer WHERE price BETWEEN o.price and (o.price + 0.99)) from offer o GROUP BY price;

Thanks to all for your great efforts. You guys rock.
