The Adapter 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 c.SiteName, o.FontName, o.CustomFontId, o.FontNumber FROM RecruitingCESites c INNER JOIN RecruitingCESitescustomFonts o ON c.siteId = o.RecruitingCESitesSiteId

Left Join

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

 SELECT c.SiteName, o.FontName, o.CustomFontId, o.FontNumber FROM RecruitingCESites c LEFT JOIN RecruitingCESitescustomFonts o ON c.siteId = o.RecruitingCESitesSiteId
