sql - Query - definition of ( table , table ) in simple mysql inner join -


i'm reconstructing search query coz it's becoming redundant in "what see" , i'm wondering

(albums_artists, artists) ( ) in join? boosting performance?

a query uses simple inner joins, using old (sql-89) implicit join syntax:

    select      ma_users.name,      ma_users.username,      albums.id album_id,      albums.upc,      albums.name album_name,     albums.status,      albuminfos.label,      date_format(albums.created, '%y-%m-%d') created_date,     concat(artists.name) artist_name,     count(tracks.id) total_tracks,     albumstatus.description album_status     albums, albuminfos, ma_users , (albums_artists, artists) , tracks ,(albumstatus, albumtypes)          albums.id = albuminfos.id      , ma_users.id = albums.account_id     , albums.id = albums_artists.artist_id      , albums_artists.artist_id = artists.id     , tracks.album_id = albums.id     , albums.status = albumstatus.id      , albumtypes.id = albums.albumtype_id     , albuminfos.label '%$keywords%'     group albums.id     order albuminfos.label

accepting opinions enhancements , errors need anticipate.

as far know parentheses redundant , don't aid query execution - may have been thought surrounding them tables treated differently i'm not aware of being true (or needed here).

by way, vma_users or ma_users? (most references ma_users without v)

personally don't favour way mysql allows group 'lazy' , prefer list out fields involved in grouping. and, wouldn't stick old join styles either. don't see syntax errors, , enhancements don't think there's enough information comment.

select        ma_users.name      , ma_users.username      , albums.id   album_id      , albums.upc      , albums.name album_name      , albums.status      , albuminfos.label      , date_format(albums.created, '%y-%m-%d') created_date      , concat (artists.name) artist_name      , count(tracks.id) total_tracks      , albumstatus.description album_status albums inner join albuminfos     on albums.id = albuminfos.id /* vma_users ?? */ inner join ma_users       on albums.account_id = ma_users.id inner join albums_artists on albums.id = albums_artists.artist_id inner join artists        on albums_artists.artist_id = artists.id inner join tracks         on albums.id = tracks.album_id inner join albumstatus    on albums.status = albumstatus.id inner join albumtypes     on albums.albumtype_id =albumtypes.id albuminfos.label '%$keywords%' group        ma_users.name      , ma_users.username      , albums.id      , albums.upc      , albums.name      , albums.status      , albuminfos.label      , albums.created /* assuming it's date times of 00:00:00 */      , albumstatus.description order albuminfos.label

well: missed inconsistency; agree spotted inner join albums_artists on albums.id = albums_artists.artist_id not right
