Feed CSV Data into FineReport

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

Set Up a JDBC Data Source of CSV Data

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

1. Copy the cdata.jdbc.csv.jar file from the lib folder in the CData JDBC Driver for CSV installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.csv.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.csv.CSVDriver
3. URL: A standard JDBC connection string using semicolon-separated connection properties.

   Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) CSV Files

   CData Drivers let you work with CSV files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.

   Setting connection properties for local files

   Set the URI property to local folder path.

   Setting connection properties for files stored in Amazon S3

   To connect to CSV file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended CSV files exist. In addition, at least set these properties:

   • AWSAccessKey: AWS Access Key (username)
   • AWSSecretKey: AWS Secret Key

   Setting connection properties for files stored in Box

   To connect to CSV file(s) within Box, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Box.

   Dropbox

   To connect to CSV file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.

   SharePoint Online (SOAP)

   To connect to CSV file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. Set User, Password, and StorageBaseURL.

   SharePoint Online REST

   To connect to CSV file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended CSV file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.

   Google Drive

   To connect to CSV file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended CSV file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.

   Built-in Connection String Designer

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

   
   java -jar cdata.jdbc.csv.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:csv:URI=/PATH/TO/MyCSVFilesFolder;
     


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 CSV set up, you can use it as FineReport data source.

Select CSV 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 CSV entities will appear as tables on the left pane.
4. Write a SELECT statement for the CSV data tables and columns that you want to load.

5. Click preview and data is shown as table.

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