Query to return the difference of dates between records - forum topic by Riny

Hi All,
I have a table with policy no,status code,status date.
I want to get the difference of the status dates for each policy(will have more than one record with different status codes)after getting sorted with the status dates for each policy.
The difference of the status dates should only consider certain status codes.
for eg: consider that 5,6 are the status codes to be considered
