Insert record into table if entry does not exist in another table- with an extra twist

Question

Hi to all you mighty SQLsuperheros out there.. Can anyone rescue me from imminent disaster and ruin?

I'm working with Microsoft Access SQL. I'd like to select records in one table (table1) that don't appear in another (table2) .. and then insert new records into table2 that are based on records in table1, as follows:

[table1] file_index : filename

[table2] file_index : celeb_name

I want to:

Select all records from table1 where [filename] is like aud and whose corresponding [file_index] value does not exist in table2 with with field [celeb_name] = 'Audrey Hepburn'

With that selection I then want to insert a new record into [table2]

[file_index] = [table1].[file_index] [celeb_name] = 'Audrey Hepburn'

There is a one to many relationship between [file_index] in [table1] and [table2] One record in [table1], to many in [table2].

Many thanks

Will this do? Obviously add some square brackets and stuff. Not too into Access myself.

INSERT INTO table2 (file_index, celeb_name)
SELECT file_index, 'Audrey Hepburn'
FROM table1
WHERE filename = 'aud'
  AND file_index NOT IN (SELECT DISTINCT file_index 
                         FROM table2 
                         WHERE celeb_name = 'Audrey Hepburn')
