Another way of doing this could be:

Select max(id) from table_name

This assumes your auto_increment field is moving upward numerically (not 
always the case) - my experience is with Oracle where you use sequences eg:

create sequence my_seq;
insert into tablename (id,textybit) values (my_seq.nextval,'sometext'); 
--sequencename.nextval is a function to grab the next available value 
from the seq
select my_seq.currval from dual; --dual is a dummy table in oracle
