The Blackbaud Raiser's Edge NXT 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.Category, c.Fundraisers, c.Summary, o.Name, o.PhoneDoNotCall FROM Actions c INNER JOIN Constituents o ON c.ConstituentId = o.Id

Left Join

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

 SELECT c.GiftStatus, o.CheckNumber, o.CheckoutTransactionId, o.PaymentMethod FROM Gifts c LEFT JOIN GiftPayments o ON c.Id = o.GiftsId
