I have a table in Oracle 11g that has the following:


Product           TYPE_CODE          Date_A
1                            01                  01/01/08
1                            04                  01/02/08
1                            01                  03/01/08
1                            06                  03/15/08
1                            01                  03/15/08
2                            01                  01/01/08
2                            04                  01/05/08
2                            01                  02/14/08
 ......

Using SQL, I would like to determine for each product  the average, min and max number of days between the first date and the second date, second and third, third and fourth, etc. for the 01 Types.

So in the above example,
For prodcut 1, I would find the difference between 03/01/08 and 01/01/08. Then compare this to the difference between 03/01/08 and 03/15/08.  
The number of rows with 01 types and dates for any given product will vary - some could have 1, some 10, some 4, etc.


Can this be accomplished in SQL?
