Java DB provides a great way to try JDBC 4.0 features

Posted by lancea on June 15, 2006 at 10:15 AM PDT

Java DB and Apache Derby have been following the progress of the JDBC 4.0 specification very closely and have implemented many of the JDBC 4.0 features in the 10.2 alpha release.

JDBC 4.0 SQLXML Interface

Posted by lancea on May 2, 2006 at 11:09 AM PDT

Since the public draft of the JDBC spec, the JDBC EG has reworked the SQLXML interface completely providing for more flexibility.

JDBC 4.0 RowId Interface

Posted by lancea on March 10, 2006 at 3:32 PM PST

The RowID interface was added to JDBC 4.0 in order to support the ROWID datatype which is supported by databases such as Oracle and DB2.

JDBC 4.0 Wrapper Interface

The Wrapper interface provides a mechanism for JDBC users to be able to access an instance of a resource which has been wrapped for architectural reasons.

JDBC 4.0 keeps moving forward

JDBC 4.0 has just completed public draft review and the EG is working on closing the last few issues. One of the interfaces that I expect to change signficantly is the SQLXML interface.

Getting Started using Derby with Glassfish and SJSAS 8.2

Posted by lancea on February 7, 2006 at 11:10 AM PST

Glassfish and SJSAS 8.2 introduce two new asadmin commands for starting and stopping the Derby Network Server.

The start-database command may be used to start an instance of the Derby network server:

start-database [––dbhost 0.0.0.0] [––dbport 1527] [–†   
  
  

Exporting Tables from Pointbase to Derby

Posted by lancea on February 6, 2006 at 4:06 PM PST

Brian Leonard has a nice article which shows you how to capture the ddl for a table in pointbase and create the same table in Derby using Netbeans 5.0.

Another option for doing this is by using the commander tool and the 'unload database' command:

./startcomma
