    Features of JDBC 3.0

    1.  Reusabilty of prepared statements by connection pools.
    2. In this version there is number of properties defined for the ConnectionPoolDataSource. These properties can be used to describe how the PooledConnection objects created by DataSource objects should be pooled.
    3. A new concept has been added to this API is of savepoints: One of the useful new features is transactional savepoints. With JDBC 3.0, the transactional model is now more flexible. Now you can start a transaction , insert several rows in it and then create a savepoint. This savepoint serves as a bookmark. The application can rollback to the savepoint and then commit the group of inserts as if the updates have never been attempted.  For eg:

      Statement sttmt=connection.createStatement();
      int rowcount=sttmt.executeUpdate("insert into employee  values("das"));
      int rowcoutn=sttmt.executeUpdate("insert into salary values(45000);
      Savepoint savept=connection.setSavePoint("savepoint"); //create save point for inserts
      int rowcount=sttmt.executeUpdate("delete from employee");
      connection.rollback(savept); //discard the delete statement but keeps the inserts
      connection.commit(); //inserts are now permanent
    4. Retrieval of parameter metadata.
    5. It has added a means of retrieving values from columns containing automatically generated values.
    6. Added a new data type i.e. java.sql.BOOLEAN.
    7. Passing parameters to CallableStatement.
    8. The data in the Blob and Clob can be altered: JDBC 3.0 introduces a standard mechanism for  updating BLOB and CLOB data. 
    9. DatabaseMetaData API has been added.
    10. It allows stored procedure parameters to be called by name. 

    Features of JDBC 4

    JDBC 4's key priority is to make it easier for developers to work directly with the JDBC API. The new features availble in J2SE 1.5 added ease-of-development features in JDBC 4

    1. Auto- loading of JDBC driver class: In JDBC 4 invoking the getConnection() on DriverManager will automatically load a driver. Upon loading the driver, an instance of the driver is created and the registerDriver() method is invoked to make that driver available to clients. 
      No need class.forname()
    2. Connection management enhancements: In jdbc it may happen that a Connection is lying idle or not closed in a pool, then it became stale over time. This will led to the connection pool run out of resources due to stale connection. We know that the stale connection doesn't mean that a connection is closed. Now in JDBC 4 Connection class we have provided one method isValid(), which allows a client to query the database driver if a connection is still valid. As database is a shared resource, so many application can access the same data store. To maintain all the records of the client is a difficult task, now in JDBC 4 an application can associate metadata with a database connection via the setClientInfo() method, which takes a name/value pair, or a Properties object. 
    3. Support for RowId data type: JDBC introduces  support for ROWID, a data type that had been in use in database products even before it became part of the SQL.
    4. SQL exception handling enhancements: JDBC 4 addresses the error handling beautifully. As databases are often remotely accessible resources, problems such as network failures is common and it can cause exceptions when executing  a database operation. SQL statements can also cause exceptions. Prior to JDBC 4, most JDBC operations generated a simple SQLException.
    5. SQL XML support:
    6. DataSet implementation of SQL using Annotations: The JDBC 4.0 specification leverages annotations to allow developers to associate a SQL query with a Java class without a need to write a lot of code to achieve this association.
