According to the MySQL documentation (Section 6.5.3, CREATE TABLE syntax): "If you don't have a PRIMARY KEY and some applications ask for the PRIMARY KEY in your tables, MySQL will return the first UNIQUE key, which doesn't have any NULL columns, as the PRIMARY KEY."
How does any application "ask for the PRIMARY KEY"? Is this an ODBC call, or are their command line and built-in functions? I couldn't find this in the documentation.
