Fri Feb 17 15:11:00 GMT 2001 peter@retep.org.uk - Reduced the object overhead in PreparedStatement by reusing the same StringBuffer object throughout. Similarly SimpleDateStamp's are alse reused in a thread save manner. - Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp using Calendar, setBlob(), setCharacterStream() - Clob's are now implemented in ResultSet & PreparedStatement! - Implemented a lot of DatabaseMetaData & ResultSetMetaData methods. We have about 18 unimplemented methods left in JDBC2 at the current time.
