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

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
