Query Instance Data

SQL queries can be executed directly through the HarperDB Studio with the following instructions:

  1. Navigate to the HarperDB Studio Organizations page.
  2. Click the appropriate organization that the instance belongs to.
  3. Select your desired instance.
  4. Click query in the instance control bar.
  5. Enter your SQL query in the SQL query window.
  6. Click Execute.

Please note, the Studio will execute the query exactly as entered. For example, if you attempt to SELECT * from a table with millions of rows, you will most likely crash your browser.
