but, i need the records to be fetch from last4...i.e,

回答1:

To get the last x number of rows, but have them returned in ascending order, use:

  SELECT x.value
    FROM (SELECT y.value
            FROM TABLE y
        ORDER BY y.value DESC
           LIMIT 4) x
ORDER BY x.value

The answer requires that you create a derived table (AKA inline view) based on the rows you want. Then the outer query re-orders the values for presentation.

回答2:

SELECT * FROM tablename ORDER BY id DESC LIMIT 0,4 

will give you the last 4 records ("last" when you order the table by id which is supposed to be an auto-increment field here.)

回答3:

If you how that there is always 6 rows you could use limit.

SELECT * FROM Tabel LIMIT 2, 4
