Extending SQuirreL with plugins

info@mhaller.de (Mike Haller) — Sat, 07 Mar 2009 16:33:16 +0100

SQuirreL is a 100% pure-Java implementation of a generic SQL client. You can browse and analyse any database which provides a JDBC driver. You can execute any kind of SQL statements. SQuirreL provides a plugin mechanism to hook in additional features. The default installation comes with a lot of plugins, for example MySQL-specific plugins, code completion, data import plugins and more.

In this article, I'd like to show you how to write your own plugin for SQuirreL and what you need to do to set up your development environment. I'll implement two features for indexing tables and their content into an Apache Lucene index and to make it searchable using full-text search.

Pagination with Apache iBatis SqlMaps

This is often the case for web application when it's not desirable to display the full contents of a database table to the users all at once. Hence the name pagination: the user can "scroll" through the results using pages. Each page contains a collection of objects and the pages usually are ordered.

Unit testing in Oracle PLSQL

info@mhaller.de (Mike Haller) — Tue, 25 Mar 2008 18:48:00 +0100

As a Java Developer, I love to develop test-driven. The 21st century is all about testing and delivering quality software. Today, my first Oracle PL/SQL Function Unit Test was born. It's not as ugly as I thought it would be, so i'm sharing my experience with you.
