in thread MySQL syntax error for ON DUPLICATE KEY UPDATE

That was it! Made perfect sense. Thanks!

my $stmt = 'INSERT INTO contact_form (' . join(',', keys %sql) . ') VALUES (' . join(',', ('?') x keys %sql) . ') ON DUPLICATE KEY UPDATE '. join(' = ?, ', keys %sql) . ' = + ?'; $self->dbh->do( $stmt, undef, (values %sql, values %sql));

    Alternatively, you can refer to the values in the insert part with the values() function:
    insert into foo (bar, baz) values (?, ?) on duplicate key update bar = values(bar) , baz = values(baz)
    So your statement string would be:
    my $stmt = 'INSERT INTO contact_form (' . join(',', keys %sql) . ') VALUES (' . join(',', ('?') x keys %sql) . ') ON DUPLICATE KEY UPDATE '. join(', ', map { "$_ = values($ +_)" } keys %sql);
