Export to database

Use the Export to database cell to append dataframes to tables attached to your notebooks. Combined with scheduled runs, this will help you have the tables in your project regularly updated with fresh data.

Suppose you retrieved data from an attached database and do some calculations. Now, you want to write the content of the dataframe containing the results of your calculations to the table. If you set up a schedule for this notebook, you ensure that the table is updated regularly and the other users work with the up-to-date source.

Export a DataFrame to a table

  1. Go to Attached data on the left-hand sidebar.

  2. Click the arrow next to the Connect SQL cell button for the required database and select Export to database cell from the expanded list.

    • Source dataframe: the dataframe that you want to append

    • Database: the database with the table you want to update
