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

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).
