That doesn't seem to work either. After dropping and adding lines to the code, it seems that the comparison line is where it hiccups.
Here is an example where I get the columns to display side by side. Still, the HAVING is where I don't yet have it. If I omit the HAVING, the query runs fine.
SELECT
O.OrderID,
O.Pieces,
PA.OrderID,
COUNT(PA.OrderID) AS TotalParcels,
COUNT(*) AS 'TotalParcels'
FROM
tblParcelAssigned as PA
INNER JOIN
tblOrder AS O
ONO.OrderID = PA.OrderID
WHERE
PA.Type = 2
-- HAVING
-- o.Pieces <> Count(*)
GROUP BY
O.OrderID,
O.Pieces,
PA.OrderID
ORDER BY
PA.OrderID
DESC
