strSql=" update REPORT set REPORT_CONTENT = ? where REPORT_ID=22" PreparedStatement preStmt = dbconn.prepareStatement ( strSql ) ;
byte[] contentBook = jBreport.writeToBlob () ;
ByteArrayInputStream inStream = new ByteArrayInputStream( contentBook ) ;
preStmt.setBinaryStream( 1 , inStream , inStream.available () ) ;
preStmt.executeUpdate () ;
其中REPORT_CONTENT就是image型。
