oracle PL/SQL: sort rows

I run this query:

 Select a.product, sum(
     case 
       when b.id=1 then round(c.sales,3)
       else 0 
     end) as Q1_2008,
 sum(
     case 
         when b.id=2 then round(c.sales,3) 
         else 0 
     end) as Q2_2008,
 sum(
     case
         when b.id=3 then round(c.sales,3) 
         else 0
     end) as Q3_2008
 from products a, quarters b, sales c
 where 
    a.id=c.PRODUCT_ID and 
    b.id=c.QUARTER_ID 
 group by a.product
 order by product

But my Product column is not in order.

PRODUCT

PROD_1
PROD_10
PROD_2
PROD_3
PROD_4
PROD_5
PROD_6
PROD_7
PROD_8
PROD_9

PROD_10 is the second row when it should be at the end. How can I fix this?

Answer 1

Here is an example of an “order by” statement that does what you want:

order by cast(substr(product, 5, 100) as int)
