Hi: I have a Java application, which needs access database. So I write JDBC. The JDBC will create a connection(or take a connection from connection pool), then create Preparedstatement, execute it, then connection commit, and prepared statement close, and connection goes back to connection pool. I find this way there are many prepared statement execution in database trace log. Are there some way to create a Prepared statement for once and execute lots of times. Or are there introduction/web links for high performace JDBC programming?
