bind_param and bind_param_inout on insert

[Stacy Mader]

I'm trying to bind paramenters on an insert and return a
value:

$sth = $dbh->prepare(q{
  INSERT INTO TEST
    VALUES (TEST_SEQ.NEXTVAL,:project_no,:issue)
      RETURNING fault_no INTO :rv
    });

$sth->bind_param(':project_no','P999');
$sth->bind_param(':issue','This is the issue.');
$sth->bind_param_inout(':rv',\$rv, 5);
$sth->execute();

Of course, when there are alot of columns, the above gets
a little untidy... I thought I could use the following:

$sth = $dbh->prepare(q{
  INSERT INTO TEST (FAULT_NO,PROJECT_NO,ISSUE)
    VALUES (TEST_SEQ.NEXTVAL,?,?)
      RETURNING fault_no INTO :rv 
    });

$x = 1;
foreach ($project_no,$issue) {
 $sth->bind_param($x,$_);
 $x++;
}
$sth->bind_param_inout(':rv',\$rv, 5);
$sth->execute();

When this statement is executed, Oracle complains:

"Can't mix placeholder styles (:foo/?) at Oracle.pm line 293."

Can the bind_param and bind_param_inout methods be
combined?
