How to Search: Web Queries

The WRDS web offers a common interface and consistent data format across all databases or datasets.

  • Start by selecting a database, then narrow down to the desired dataset.
  • Choose your data
  • Chose your date range
  • Select your company codes or tickers. Code lists can be imported or saved on the WRDS platform. 
  • Select your query variables
  • Select your query output type

When you submit a query, it runs on WRDS servers, and your results will be made available for you to download when it is complete.
