The CData SSIS Components for Salesloft 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 Actions.Type, ActionDetails.Instructions  FROM Actions INNER JOIN ActionDetails ON Actions.ActionDetailsId = ActionDetails.Id

Left Join

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

SELECT Actions.Type, ActionDetails.Instructions  FROM Actions LEFT JOIN ActionDetails ON Actions.ActionDetailsId = ActionDetails.Id
