Here is a code snippet that I have used to read from a CLOB, Oracle 10g instance.

PreparedStatment ps = connection.prepareStatement
("SELECT clobcolumn from clobtable");
ResultSet rs = ps.executeQuery();
while(rs.next())
{
oracle.sql.CLOB clobValue = (oracle.sql.CLOB)rs.getCLOB(1);
BufferedReader reader = new BufferedReader(new
InputStreamReader(clobValue.getAsciiStream()));
String read = null;
StringBuffer buffer = new StringBuffer();
while((read = reader.readLine()) != null )
{
buffer.append(read);
}
}

We will configure the SQL Explorer Plug-in & connect to the database. I will be using MySql server. It will be almost the same for all the databases. If you have not yet installed the plug-in please see my post on Installing Eclipse SQL Explorer Plug-in.

• From the eclipse menu, select window->preferences
• In the preference dialog box, select the SQL Explorer node.
• Select the JDBC Drivers node.
• Select the Driver you want to configure. We will configure MySQL Driver. So select the MySQL Driver & click edit on the right hand side.
• Select the “extra class path” tab in the change dialog box.
• Add the MySQL Connector jar file by clicking on add button. You can download the connectors from MySQL site. You can download it directly from here.
• Once you added the jar file click on List Drivers on the right hand side. You can see all the loaded drivers. Select the one appropriate to you.
• Enter the URL of your MySQL Server in the Example URL text box. Something like this “jdbc:mysql://localhost:3306/test”. Here “test” is the database name & enter the url without quotes.
• Click ok to finish the installation of the driver. You should be able to see a green tick mark for the driver we just installed.

Now we will connect to the database.

• From the eclipse menu, select window->Open Perspective->other.
• In the Open Perspective dialog box select SQL Explorer & click ok.
• Eclipse will be switched to SQL Explorer perspective.
