Originally posted by George Larry: I thought I could do this... String[] listNames = rs.getArray( "name" ); But that's not working... It would work only for SQL3 Datatypes, if the Database column type is SQL ARRAY, which means each field contains an actual array. But in your case each field contains a String. To convert your resultset into an array you ...

23. Are ResultSets Thread Safe?

ResultSets are not thread safe and by default they can only be looped through once. Scrollable ResultSets and CachedRowSets can be looped through more than once though. Also ResultSets are not serializable (so can't be returned from EJBs). Check out the FormattedDataSet for an easy way to convert ResultSets to HTML or XML or any other text. The FormattedDataSet can also ...

37. displaying next record in DB using ResultSet

Well, you're going about it a bit backwards. If you want to show only one record at a time, the best method would be to only fetch one record at a time. Grabbing and holding onto a result set is a very poor idea. DB resources should be released as soon as possible.

49. Send resultset from servlet to jsp

Neither is a good idea for a result set. Binding it to servletContext will keep it around for the life of your application. Binding it to session will keep it around for the length of your user's session. Since a resultSet is not really a datastructure and is more of a pipe to your database, binding to anything that will last ...

51. display resultset from servlet on jsp

Strictly speaking, you should never have a resultset in a servlet. DB access should happen at a lower layer, with non-DB constructs passed up to the UI layer.

63. Caching Database resultset

The second level cache will not cache this unless you have configured the query cache, and then it will cache the IDs only. "Session scope" could mean a bunch of things here. If it s the Hibernate Session, you are already caching there (assuming you load the objects you return from this query into the Hibernate session). If its the EJB ...

If you're using JSTL to write ...
