Using the Query Builder

The default view is a query builder which is in active development:

  • This will auto populate your available columns for your select statement. Use the + and - buttons to add or remove additional where statements.
  • You can overwrite a dropdown field by typing in your desired value (e.g. *).
  • The where field is a text entry where you can define any where clauses. Use the + and - buttons to add or remove additional where statements.
  • You can switch to a raw SQL input by pressing the "Edit SQL" button. This will show you the query you have been building thus far and allow you to enter any query.
  • Press the "Run query" button to see your results.
  • From there you can add to dashboards and create any additional dashboards you like.
