JOIN Queries
The CData ADO.NET Provider for Salesforce Marketing Cloud Account Engagement 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 p.CampaignId, p.Email, pa.CreatedAt FROM Prospects p INNER JOIN ProspectAccounts pa ON p.ProspectAccountId = pa.Id
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT v.Id, v.ProspectId, v.CreatedAt, vs.PageViewCount, vs.IpAddress FROM Visits v LEFT JOIN Visitors vs ON v.VisitorId = vs.Id
