Answer 1

You'll want to use the WHERE EXISTS syntax instead.

SELECT *
FROM table1
WHERE EXISTS (SELECT *
              FROM table2
              WHERE Lead_Key = @Lead_Key
                        AND table1.CM_PLAN_ID = table2.CM_PLAN_ID
                        AND table1.Individual_ID = table2.Individual_ID)
