Database.upsert optional External Id parameter

What happens if I don't provide the optional External Id parameter for a Database.Upsert call?

Will an insert be performed?

Thanks in advance

The External_ID_Field parameter is not optional - see the docs (http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_methods_system_database.htm#apex_System_Database_upsert).
