Here is the Select I need to convert to an Update:
SELECT DISTINCT f.SectionID, f.Name, v.Enabled
FROM SETTING_VALUE v
INNER JOIN SETTING s ON v.SettingID =
Based on your comment, all of the matching rows should be updated you don't need distinct. Just execute this:
UPDATE SETTING_VALUE
SET Enabled = 0
FROM SETTING_VALUE v
INNER JOIN SETTING s ON v.SettingID = s.SettingID
INNER JOIN LU_FIELD f ON f.FieldID = s.FieldID
WHERE v.DisplayValue LIKE '%Miami%'
AND f.ControlName LIKE '%City%'
Everything that you saw in your select will be updated.
