Perl DBI Calling Oracle Procedure

How does one invoke stored procedures with DBI?
There is currently no standard way to call stored procedures with DBI. However, if you have created a stored procedure within an Oracle database, you can use $dbh->do() to immediately execute the procedure:
$dbh->do("BEGIN myPackage.myProcedure; END;");

Or
Sample:
my $sth=$dbh_o->prepare("begin PRO_BID_QUEUE_TABLE(:in1,:int2,:T); end;");
$sth->bind_param("in1",20);
$sth->bind_param("in2",30);
my $result;
$sth->bind_param_inout("T",\$result,20);
$sth->execute();
$sth->commit();

CREATE OR REPLACE PROCEDURE
PRO_BID_QUEUE_TABLE( N1 IN NUMBER , N2 IN NUMBER , TOTAL OUT NUMBER)
IS
BEGIN
TOTAL := N1 + N2 ;
END;
