Hi insert_id returns the key value. I use php, and the mysql_insert_id is the last insert_id on that connection, so even if other processes have added new records in the time the script runs the insert_id is the correct one.
You can then use that as the key in the detail records.

There is a foreign key on the detail table set to the unique key (autoinc) field of the master table. Inserting a master record, even with a special field value so that it can be quickly returned with the newly created primary key, so that I might then insert the detail records with this primary key as their foreign key, does not seem very reliable to me (as suggested a few days ago). There must be a more reliable way to do this under heavy traffic. I'm afraid I'm used to being able to grab a generator ID and using that (guaranteed to be unique) for both the primary key of the master and the foreign key of the detail records. Surely there is a good method for use with MySQL....?
