The Stripe Adapter supports standard SQL joins like the following examples.

Inner Join

An inner join selects only rows from both tables that match the join condition:

SELECT Charges.Amount, Customers.Email FROM Customers INNER JOIN Charges ON Charges.CustomerId = Customers.Id

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

SELECT Charges.Amount, Customers.Email FROM Customers LEFT JOIN Charges ON Charges.CustomerId = Customers.Id
