JDBC Driver for CSV

Build 22.0.8462

JOIN Queries

The CData JDBC Driver for CSV 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 prod.Id, prod.Name, det.Details FROM Products prod INNER JOIN ProductDetails det ON prod.Id = det.ProductId

Left Join

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

 SELECT prod.Id, prod.Name, det.Details FROM Products prod LEFT JOIN ProductDetails det ON prod.Id = det.ProductId
