Here is an example of how to retrieve a list of all orders and the corresponding customer name for each order: We define user as a relationship to a user class instance that back populates to the user_library table. We can achieve the joins (extracting data from multiple tables) using sqlalchemy. In sqlalchemy, we perform inner joins through the join() method. You learned how to link between two related tables using an association table (also called a join table), associate an entry with another, add the entry to the database, and access. To join these two tables using sqlalchemy core, developers can use the join() function.
