Feed Oracle Data into FineReport

The CData JDBC Driver for Oracle fully implements the JDBC standard and can provide Oracle data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Oracle data as JDBC data source in FineReport and view Oracle data as a table in the Report Designer.

Set Up a JDBC Data Source of Oracle Data

Follow the instruction below to set Oracle data as a FineReport database connection.

1. Copy the cdata.jdbc.oracleoci.jar file from the lib folder in the CData JDBC Driver for Oracle installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.oracleoci.lic file as well.
2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.

Next we will set up the data connection definition in the window.

1. Database: Others
2. JDBC Driver: cdata.jdbc.oracleoci.OracleOCIDriver
3. URL: A standard JDBC connection string using semicolon-separated connection properties.

   To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

   • Port: The port used to connect to the server hosting the Oracle database.
   • User: The user Id provided for authentication with the Oracle database.
   • Password: The password provided for authentication with the Oracle database.
   • Service Name: The service name of the Oracle database.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.oracleoci.jar

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

   When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

   A typical JDBC URL is below:

   jdbc:oracleoci:User=myuser;Password=mypassword;Server=localhost;Port=1521;
4. Click Connection pool attributes and set Test before getting connections to No.

Click Test connection to ensure you have configured the connection properly. With the connection to Oracle set up, you can use it as FineReport data source.

Select Oracle Data in the Report Designer.

1. Click to add a new template data set and select DB query to open the database query window.
2. Choose the JDBC connection that you created from the dropdown list.
3. The Oracle entities will appear as tables on the left pane.
4. Write a SELECT statement for the Oracle data tables and columns that you want to load.
5. Click preview and data is shown as table.

With these simple steps, Oracle can be used as a JDBC data source in FineReport.
