Update mysql table with data from another table

Question

Is it possible to run an UPDATE command on mysql 5.0 with a sub select.

The command I would like to run is this:

UPDATE book_details
SET live = 1 
WHERE ISBN13 = '(SELECT ISBN13 FROM book_details_old WHERE live = 1)';

ISBN13 is currently stored as a string.

This should be updating 10k+ rows.

Thanks,

William
