1) Replace the USING() to ON office_list.office = verification_date.office
Find all of the columns in your WHERE clause that are in your
Verification_Data table and move these criteria to ON clause.
SELECT office_list.office, verification_data.period
FROM office_list
LEFT OUTER JOIN verification_data
ON Office_list.office = verification_data.office
AND start_time > 'yesterday'
AND start_time < 'today'
WHERE period=1
AND name='foo'
AND element='bar';
