Question

I’m trying to delete the most lower 60 rows but its not working.
I tried some other posts in stackoverflow but non of them worked for me.

DELETE FROM windUpdates 
WHERE INDEX <= ( 
                  ( SELECT MAX(  INDEX )  FROM windUpdates )  - 60
               )

Thanks.

Answer 1

you need to create temporary table for the result of your subquery,

DELETE FROM tablename
WHERE `Index` NOT IN
(
  SELECT `Index`
  FROM
    (
      SELECT `Index`
      FROM tablename
      ORDER BY `Index` DESC
      LIMIT 60
    ) x
)

PS: Be sure to backup your database first.
