Which type of result set has best performace for a read only purpose ?
is it wise to use

ResultSet.TYPE_SCROLL_INSENSITIVE , ResultSet.CONCUR_READ_ONLY
i just want to retrive one column of one record (my query will return just one record)

thank you

Raminaa,
ResultSet.TYPE_FORWARD_ONLY , ResultSet.CONCUR_READ_ONLY is best here. You don't need any scrolling capability or to update the data.

That's true. Personally I only ever use forward-only, read-only result sets. However if your query is only returning one record, the choice is going to make almost no difference in practice.
