I read someplace that the CVS version may support it. Unfortunately, gborg seems to be down for the past day or so. Looking through the code, I see things like:
while (x_rset.next()) {
x_rset.previous()
function_that_calls_next(x_rset)
}
Is there a better way to do this? With result pointers from other languages, like perl, python, php, I know the size of the result so I can choose the type of loop I want to use. Is there a better way to loop through a result set and have a another function call next?

Matt,
no they are not broken.
But AFAIK a ScrollableResultSet with Postgres JDBC supports forward only. Try again with different settings and of course don't call previous().
If you need scroll back functionality you could use cursors.

Betreff: [JDBC] scollable result sets
Are they broken in 8.1? I no matter what I do Postgresl throws an exception with calls to functions like previous() and last().
x_conn.prepareCall ( os_query, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY );--
