The CData ODBC Driver for Amazon DynamoDB 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 i.Amount, c.CustomerName FROM Invoices i, Customers c WHERE i.CustomerName = c.CustomerName

Left Join

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

SELECT i.Amount, c.CustomerName FROM Customers c LEFT JOIN Invoices i ON i.CustomerName = c.CustomerName
