JDBC Driver for Presto

Build 20.0.7654

JOIN Queries

The CData JDBC Driver for Presto 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 Customer.FirstName, Customer.LastName, Purchases.ItemName FROM Purchases INNER JOIN Customer ON Purchases.CustomerId = Customer.Id

Left Join

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

SELECT Customer.FirstName, Customer.LastName, Purchases.ItemName FROM Purchases LEFT JOIN Customer ON Purchases.CustomerId = Customer.Id
