Greetings, chuleto1!

When executing an existing stored procedure via DBI, I have often used a structure like the following:

sub call_assign_value_func {
  my $some_num = shift;
  my $func_value = -1;
  my $pkgh = $dbh->prepare("BEGIN :result :=
    PKG_SIMULATOR.F_ASSIGN_VALUE(:some_num); END;");
  $pkgh->bind_param(":some_num", $some_num);
  $pkgh->bind_param_inout(":result", \$func_value, 15);
  $pkgh->execute();
  return $func_value;
}
[download]

I am basically creating an anonymous PL/SQL block to execute the desired stored procedure, (or function in this case.) Using the $pkgh->bind_param and $pkgh->bind_param_inout calls allows for much greater flexibility when working with some of the stored procedures I have.

Hope this helps!

• 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).
