As this is a single table query, there is no need for the table alias.
SELECT Name FROM SMS_R_System WHERE LEFT(SystemOUName, 34) =
'example.com/COMPUTERS/MAIN CAMPUS/' AND RIGHT(SystemOUName, 3) IN
('ABC', 'XYZ')
But this will probably take a measurable amount of time longer to
execute - 2 comparisons and 2 string processes. Maybe not for a single
run, but after several hundred.
