you need a combination of two of the replies: 
foreach my $element ( keys %dateparts ) {
    die "No datepart!: $!" unless defined $dateparts{$element};
}

the 'exit' is redundant. if the code dies, the program is exiting.

i also don't think your assignment is going to work correctly. if you're passing in date values, you really should just use something like: 

my %dateparts = @_;

assuming that your input args are in the form of: 

sub MySQLIN( YEAR => '1999', DAY => '10', MONTH => '3');

the join will work even if the values to join are undefined.
