MySQL Delete-Select row -


i'm trying delete row table subscription there 2 foreign keys (id_user , id_journal). information have email table user , nome table journal. deleted row needs match user.email , journal.nome. can't find solution. how can it?

table user:

id name email password

table journal:

id name

table subscription:

id id_user id_journal

the last 2 queries tried:

delete assinatura ( select  tbluser.id, journal.id    tbluser, journal email = '$email' , nome = '$nome')  delete assinatura  inner join tbluser on (tbluser.email = '$email') inner join journal on (journal.nome = '$nome')

i've tried many others queries, unsuccessful. think it's important i'm new @ mysql.

delete  subscription id_user in (    select      usr.id            user usr           usr.email = input_email )  , id_journal in (    select      jrnl.id            journal jrnl           jrnl.name = input_name )
