Creating User Defined Extensions in Oracle SQL Developer

Purpose

This tutorial shows you how to add XML extensions to Oracle SQL Developer.

Time to Complete

Approximately 40 mins.

Overview

Oracle SQL Developer is a free graphical tool that enhances productivity and simplifies database developmenttasks. Using Oracle SQL Developer, you can browse database objects, run SQL statements, edit and debugPL/SQL statements and run reports, whether provided or created.

Developed in Java, Oracle SQL Developer runs on Windows, Linux and the Mac OS X. This is a greatadvantage to the increasing number of developers using alternative platforms. Oracle SQL Developer is built onan extensible framework and, as such, is extensible itself. You can create basic XML extensions or moreinvolved Java extensions to add utilities or other functionality to the product.

Prerequisites

Before starting this tutorial, you should:

Install Oracle SQL Developer 3.0 from OTN. Follow the release notes here.Install the Oracle Database 11g.Unlock the HR user. Login to SQL Developer as the SYS user and execute the following command:alter user hr identified by hr account unlock;Download and unzip the sql_files.zip file that contains all the files you need to perform this tutorial.

Creating a Database Connection

To create a database connection, perform the following steps:

Note: If you already have a database connection, you need not perform the following steps, you can movestraight to Sharing Reports.

1 . If you installed the SQL Developer icon on your desktop, click the icon to start your SQL Developer and move3. If you do not have the icon located on your desktop, perform the following steps to create a shortcut to launDeveloper 3.0 directly from your desktop.

Open the directory where the SQL Developer 3.0 is located, right-click sqldeveloper.exe (on Windows) orsqldeveloper.sh (on Linux) and select Send to > Desktop (create shortcut).

3 . In the Connections tab, right-click Connections and select New Connection.

Note: If this tab is not visible, select View > Connections.

4 . Enter the following and click Test:

Connection Name: HR_ORCLUsername: hrPassword: <your_password>Select Save PasswordHostname: localhostPort: 1521SID: <your_SID>
