How do I access data through WRDS?

  1. You can access data using your browser:

Use Our Web Query Forms

All you need is a web browser and Internet access to query data from WRDS. After you've decided on which dataset to use, you can use our web-based query form to extract and output data in the format of your choice. Each dataset on WRDS includes a description of what's included as well as links to the pages for each query. The web-based version of WRDS is designed to work with any modern browser.

Our web queries have the same general format for all databases in WRDS. Full documentation: Web Queries or Introduction to Web Queries

Use SAS Studio
Access WRDS data from any web browser using SAS Studio. SAS Studio is a web-based version of SAS, that combines the ease of a point-and-click web interface with the power of the underlying SAS language and data files. WRDS provides data in SAS format, allowing native querying of WRDS data right within your SAS programs. Full documentation: SAS Studio Direct link: SAS Studio (upenn.edu)

Use RStudio Server
With a minimal amount of setup, WRDS provides a direct interface for R access, allowing native querying of WRDS data right within your R program. All WRDS data is stored in a PostgreSQL database, and is available through R via a native R Postgres driver. Full documentation: RStudio Server Direct link: https://wrds-rstudio.wharton.upenn.edu/
