JOIN Queries
The CData ODBC Driver for ServiceNow 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 incident.close_notes, system_user.name FROM incident INNER JOIN system_user ON incident.caller_id = system_user.system_id
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT incident.close_notes, system_user.name FROM incident LEFT JOIN system_user ON incident.caller_id = system_user.system_id
