Now have been in a position to get started querying! The outlined magnificence handiest supplies a handful of fundamental purposes. Let’s stroll thru how to use the category and what we will be able to do with it.

First, we’ll want to specify our PostgreSQL connection arguments, and SSH arguments (if SSH tunneling is needed to get entry to the far off server).

Finally, we will be able to use .question() to run same old SQL queries (for PostgreSQL). In this situation we’re querying the column names and information sorts from the desk named ‘ey_test_table

Try changing the contents of sql_statement with your individual question, and feature amusing!
