I suppose you could use a solution such as this one    select name  length name  from users where id         select id     from users     order by length name  desc     limit 1      Might not be the optimal solution  though    But seems to work

select    from my table  where length  Name              select max  length  Name            from my table       limit 1       It this involves two table scans  and so might not be very fast

Use CHAR LENGTH   instead-of LENGTH   as suggested in   MySQL - length   vs char length    SELECT name  CHAR LENGTH name  AS mlen FROM mytable ORDER BY mlen DESC LIMIT 1
