The CData ADO.NET Provider for SAS Xpt 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.SampleCol1, o.SampleCol2, o.SampleCol3, o.SampleCol4 FROM SampleTable_1 c INNER JOIN SampleTable_2 o ON c.Id = o.Id2

Left Join

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

 SELECT c.SampleCol1, o.SampleCol2, o.SampleCol3, o.SampleCol4 FROM SampleTable_1 c LEFT JOIN SampleTable_2 o ON c.Id = o.Id2
