How to connect to DB2 Data from IntelliJ

The CData JDBC Driver for DB2 enables you to access DB2 as a JDBC data source, providing integration with rapid development tools in IDEs. This article shows how to use the data source configuration wizard to connect to DB2 data in IntelliJ.

Create a JBDC Data Source for DB2

Follow the steps below to add the driver JAR and define connection properties required to connect to DB2 data.

1. In the Data Sources window, right-click and then click Add Data Source -> DB Data Source.

2. In the Data Source Properties dialog that appears, the following properties are required:

   • JDBC Driver Files: Click the button next to this menu to add the JDBC Driver file cdata.jdbc.db2.jar, located in the installation directory.
   • JDBC Driver Class: In this menu, select cdata.jdbc.db2.DB2Driver from the list.

   • Database URL: Enter the connection URL in the JDBC URL property. The URL must start with jdbc:db2: and includes connection properties separated with semicolons.

     Set the following properties to connect to DB2:

     • Server: Set this to the name of the server running DB2.
     • Port: Set this to the port the DB2 server is listening on.
     • Database: Set this to the name of the DB2 database.
     • User: Set this to the username of a user allowed to access the database.
     • Password: Set this to the password of a user allowed to access the database.

     You will also need to install the corresponding DB2 driver:

     • Windows: Install the IBM Data Server Provider for .NET.

       On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

     • Java: Install the IBM Data Server Driver for JDBC.

       In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the DB2 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.db2.jar
     

     Fill in the connection properties and copy the connection string to the clipboard.

     A typical JDBC URL is the following:

     jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;

Edit and Save DB2 Data

To discover schema information, right-click the data source you just created and click Refresh Tables. To query a table, right-click it and then click Open Tables Editor. You can also modify records in the Table Editor.
