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

UPDATE table1 t1, table2 t2 SET t1.field_to_change = t2.field_with_data WHERE t1.field1 = t2.field2;
