JDBC Driver for REST

Build 20.0.7654

JOIN Queries

The CData JDBC Driver for REST 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 
  [people].[personal.age] AS age, 
  [people].[personal.gender] AS gender, 
  [people].[personal.name.first] AS first_name, 
  [people].[personal.name.last] AS last_name, 
  [vehicles].[model], 
FROM 
  [people], [vehicles] 
WHERE 
  [people].[_id] = [vehicles].[people_id]

Left Join

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

SELECT 
  [people].[personal.age] AS age, 
  [people].[personal.gender] AS gender, 
  [people].[personal.name.first] AS first_name, 
  [people].[personal.name.last] AS last_name, 
  [vehicles].[model], 
FROM 
  [people]
LEFT OUTER JOIN 
  [vehicles] 
ON
  [people].[_id] = [vehicles].[people_id]
