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.
 
It is sorta covered in the JavaRanch Style Guide.
