Ha :). I can think of 3 different scenarios: 1) Two columns of a table form a combined unique key, but neither of them can be defined UNIQUE(). 2) You have a "unique key" that spans several tables: CREATE TABLE bars ( id INTEGER AUTO_INCREMENT PRIMARY KEY NOT NULL, string VARCHAR(255), UNIQUE(string) )Type=InnoDB; CREATE TABLE foos ( id INTEGER AUTO_INCREMENT PRIMARY KEY NOT NULL, bar_id INTEGER, UNIQUE(bar_id), FOREIGN KEY(bar_id) REFERENCES bars(id), INDEX(bar_id) )Type=InnoDB; my $foo = Rosetest::Foo->new(bar => { string => "moo!" }); $foo->load(speculative => 1); # Error $foo->save(); 3) The application isn't at liberty to change the db and must work with a crappy legacy schema. -- Mike Mike Schilli [EMAIL PROTECTED] > > It's something that I'm running into quite frequently: > > I want to find out whether a matching record exists or not, and > > load it if so.
