what sort of magic is that ?
$sth->execute_array({ ArrayTupleStatus => \my @tuple}) or die $sth->errstr;
It depends on which portion of that line seems like "magic" to you.
- LanX answered with the execute_array description.
- ArrayTupleStatus is described in the DBI bind_param_array and execute_array documentation.
- \my @tuple syntax is shown in the examples of that DBI documentation. The concept of creating an array and immediately getting a reference to that array is described in perlref: Assigning-to-References, and is essentially shorthand for calling my @tuple; in one line and then using \@tuple in the execute_array() call to pass the reference to the function. (This is my best guess as to what you would consider the "magic" portion of that line of code.)
- or die $sth->errstr is the typical way to raise an error with DBI, unless you use RaiseError
