Question

When inserting or updating data in DB (Oracle DB in my case) using Java, which is better to use:

• ResultSet.insertRow(), ResultSet.updateRow() or
• Statement.executeUpdate(....)

Most of the time I use rs.insertRow() and rs.updateRow(), in that way avoiding the need to write queries, but is that justified performance-wise ?

Answer 1

I never do anything with ResultSet except walk through it, map it into objects or data structures, and close it. If I want to INSERT, I do it with PreparedStatement. My ResultSets never stick around long enough to be modified. I prefer to keep persistence operations short so I can close the connection as quickly as possible. I think this approach scales better, because it’s easier for multiple users to share pooled connections that way.
