Don't forget that if you "commit" then last_insert_id will return 0

The sequence is : - do insert of record with auto-increment column : - get value of last_insterted_id (i.e., the value asigned to the : auto-increment column to that record). There is only one column so there : is no need for figuring out which column. : : If you do two inserts you must get the last_inserted_id BETWEEN the : inserts. If the second table also has a auto-increment column you will : have to get its value after that insert. : : Hope this helps. : : William R.
