Dynamic SQL place holders - PERL

Hi,

Our PERL scripts have some dynamic SQL place holders which are giving
problems.

*code snippet:*
**
*$dbh->ct_dyn_prepare("update emp set deptid=888 where empno=?");
   $dbh->ct_dyn_execute(["234567"]);*
**

When I execute the perl script I get an error saying *parameter is not
passed... .*

I have seen in the previous posts that dynamic SQL place holders do not work
with freeTDS.
I am using freetds-0.83.dev.20100122, any patches are available now or any
advice?

Thanks,
Mahendra
