Connect to Quandl Data in RazorSQL

Connect to Quandl from wizards and query Quandl data from the GUI in the RazorSQL database management tool.

The CData JDBC Driver for Quandl enables standards-based access from third-party tools, from wizards in IDEs to data management and analysis tools. This article shows how to connect to Quandl using wizards in RazorSQL.

Create a JDBC Data Source for Quandl Data

  1. Open the RazorSQL application and, in the Connections menu, select Add Connection Profile -> Other -> JDBC.
  2. In the Connection Wizard that appears, set the following properties:
    • Driver Location: Set this property to the path to the lib subfolder in the installation directory.
    • Driver Class: Set the driver class to cdata.jdbc.quandl.QuandlDriver.
    • Username: Enter the username. (This property can also be set in the JDBC URL.)
    • Password: Enter the password. (This property can also be set in the JDBC URL.)
    • JDBC URL: Enter connection parameters. The JDBC URL begins with jdbc:quandl: and is followed by a semicolon-separated list of connection properties.

      Quandl uses an API key for authentication. See the help documentation for a guide to obtaining the APIKey property.

      Additionally, set the DatabaseCode connection property to the code identifying the Database whose Datasets you want to query with SQL. You can search the available Databases by querying the Databases view.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.quandl.jar

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

      A typical JDBC URL is the following:

      jdbc:quandl:APIKey=abc123;DatabaseCode=WIKI;

Query Quandl Data and Select Tables

After establishing a connection, the wizard will close and the connection will be available in the connections panel. You can then query the tables.
