mysql - do the data aggregation with min value of other field -

-

i have 1 table in mysql database.

name age code foo  24  23 bar  23  21 mit  19  23

and doing data aggregation on basis of "code" attribute, using "group by" in mysql this

select * table group code

output

foo 24 23 bar 23 21

i interested in aggregated result min age.

expected output 

mit 19 23 bar 23 21

i looking optimized query that.

thanks in advance. please let me know if need more detail.

you want row has minimum age each code. means there no smaller age code. here 1 method:

select t.* table t not exists (select 1 t2 t2.code = t.code , t2.age < t.age);
