Hi,
Why does the function to retrieve the minimum LSN allow you to specify a capture instance, but not the function to retrieve the maximum LSN?
If I wanted to find out the last change made to a row in a tracked table, I would want to use the max LSN for a table rather than for everything that is being tracked (i.e. same reasoning as for retrieving the min LSN).
I don't know enough about LSN's to know whether they increase numerically as they are created - for instance, if I query for the MAX(LSN) in the tracking table, does that give me the most recent row added?
I am also looking at determining the last update that was made to a particular column in a tracked table (to retrieve its previous value), so understanding how to work with max LSN values will be very useful!
I do understand that I can use the time mapping functions to convert to and from LSN values, but I am wondering if I can be more direct in the querying by using the LSN itself.
Thanks in advance!
Dan
