    Default How to delete items NOT in a list

    I have a table with current movie titles identified by ID number and another
    table with reviews of those items, also containing the ID number. The table of
    current films is updated daily from an external file. The reviews go untouched.
    How do I remove reviews that are NOT in the list of current films?

    Table 1: FilmCode, FilmTitle
    Table 2: FilmCode, Review

    - Baffled
