Hi again
b) retrieve the last record

Assuming you have a column x which imposes the order you're after:
SELECT MAX(x) FROM t
to get the max key
SELECT * FROM t WHERE x=<max key>

I have a primary key comprising first two columns Date and Hours e.g.
01-01-2009, 6
And so what do I change the above code suggestion to ?
You can always order the results and select one row:
SELECT * FROM t ORDER BY datecol DESC, hourcol DESC FETCH FIRST ROW ONLY
Sounds like you need to read a good book on SQL and also a tutorial on JDBC.
