Hi,
One possible solution for your problem would be: As you have the last update date, you can perform an ORDER BY date DESC and then LIMIT 1.
This will give you only the row which was last updated.

Try this: -
-
SELECT date,item,quantity,balance from total t WHERE date = (SELECT MAX(date) FROM total WHERE item = t.item GROUP BY item)
