The CData Excel Add-In for Quickbase 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
