If you want to use absolute() (or relative(), first(), last(),
prev()), you must specify TYPE_SCROLLABLE_xxx when creating the
statement, per the spec. The default is TYPE_FORWARD_ONLY, which as
the name implies creates resultsets that can only be iterated through
forwards using next(). See the ResultSet javadoc for details:

I use this code,


<fixed>stmt =
DBConnection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);</fixed>


but still get this error


ERROR:Operation requires a scrollable resultset, but this resultset is
FORWARD_ONLY.

org.postgresql.util.PSQLException: Operation requires a scrollable
resultset, but this resultset is FORWARD_ONLY.



do I need to specify anything else in the statment?


Thanks v much

I use this code,

stmt =
DBConnection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet
.CONCUR_UPDATABLE);

but still get this error

FORWARD_ONLY.
