mysql - Select only the last inserted item related to another registry -

-

i modeled small database easier explanation: 

create table bands (   id integer unsigned not null auto_increment,   name varchar(120) null,   primary key(id) ) type=innodb;  create table albums (   id integer unsigned not null auto_increment,   band_id integer unsigned not null,   album_name varchar(120) null,   rating integer unsigned null,   insertion_date timestamp null,   primary key(id),   index albums_fkindex1(band_id),   foreign key(band_id)     references bands(id)       on delete no action       on update no action ) type=innodb;

now, pretending have bands , many albums registered in respective tables, want select last inserted album each registered band.

ps: have use "album.insertion_date" field determine album last inserted.

try joining 2 tables , filtering insertion_date , band:

select al.* albums al inner join bands b on al.band_id=b.id al.insertion_date=(     select max(insertion_date)     albums     band_id=b.id )
