Aggiorna la colonna del set di tabelle uguale per selezionare dove l'id corrisponde al di fuori della query in Oracle

Quando usi WITH con UPDATE devi usare l'alias per la tabella di aggiornamento. In caso contrario, non funziona.

Inoltre, non puoi invocare la TABELLA AGGIORNATA nella CLAUSOLA WITH, in quel momento quella tabella è sconosciuta, ecco perché ottieni IDENTIFICATORE NON VALIDO. Per risolvere il problema è necessario rimuovere quella condizione e aggiungerla alla fine.

Prova questo, ma sto scrivendo senza nemmeno conoscere il modello di dati, quindi fai attenzione.
