ranking - Get current rank using mysql -

-

i've got query rank of rows, order field

set @rank=0; select @rank:=@rank+1 rank, id, ammopacks   users   group id   order ammopacks desc;

how getting rank of "x" id, without ranking them before? don't want know users rank, 1 id.

is possible?

thanks in advance

you can subquery:

select count(*) rank users u u.ammopacks >= (select ammopacks users u2 u2.id = x)

this doesn't same thing. real ranking, users same value of ammopacks have same rank. original give different users different sequential values in case.

to effect, can do:

select count(*) rank users u u.ammopacks > (select ammopacks users u2 u2.id = x) or       (u.ammopacks = (select ammopacks users u2 u2.id = x) ,        u.id <= x       )
