Hi Kris and thank you for your fast answer..
my problem is to retrieve the last autogenerated key after an insert
statement.
i always used this method (mashing queries together where the last is a
currval query).
What i should use to have the same result in pgsql8?
i apologize that java.sql.Statement.getGeneratedKeys() isn't still
implemented.
thanks!
