JOIN Queries
The CData Excel Add-In for Elasticsearch 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
