Query Quandl Data in MySQL Workbench

Execute MySQL queries against live Quandl data from MySQL Workbench.

You can use the SQL Gateway from the ODBC Driver for Quandl to query Quandl data through a MySQL interface. Follow the procedure below to start the MySQL remoting service of the SQL Gateway and work with live Quandl data in MySQL Workbench.

Connect to Quandl Data

If you have not already done so, provide values for the required connection properties in the data source name (DSN). You can use the built-in Microsoft ODBC Data Source Administrator to configure the DSN. This is also the last step of the driver installation. See the "Getting Started" chapter in the help documentation for a guide to using the Microsoft ODBC Data Source Administrator to create and configure a DSN.

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.

Configure the SQL Gateway

See the SQL Gateway Overview to set up connectivity to Quandl data as a virtual MySQL database. You will configure a MySQL remoting service that listens for MySQL requests from clients. The service can be configured in the SQL Gateway UI.
