Tricky query question

Hi All,

This is a question for those who like writing tricky queries as a single SQL... Assume I have a table with the following structure (imaginary table to keep example simple):

primarykey number(8)
status char(1)
dateinserted date
<many other fields which are insignificant>

A row is inserted into this table any time one, or more, fields change for the record. What I'm trying to determine is the "dateinserted" for each time the value of "status" changed - remembering that there might be 50 records for the primary key and five of those include a change in status - I want the dates of those five records (plus the value of status at each date).

Is there any way to achieve this within a single SQL statement? I realise that I could cursor through each record in date order and use a variable to store the previous value of status - but I'd love to compress this to a single statement. I've seen the syntax "OVER" used in some queries and suspect this may be useful but I really don't understand it enough to know.

Thanks in advance if you can help me on this one,

Mark.

PS: Sorry if this appears more than once - I've been getting mail server failures all day
