I am trying to write a reentrant sub that will execute sql select statements e.g. 

GetChildren($objID);

Sub GetChildren{
  ($objid)=@_;
  my $sth = $dbh->prepare("select objid,type from table where  parenti
+d=?")
  $sth->execute($objid)
  while (@row = $sth->fetchrow_array){
      ($objid, $type)=@row;
      if($type="Container"){
         GetChildren($objid);
      }else{
         do something else
      }
  }

The problem is that the $sth is already executing the query, when the subroutine is called for the second time. Is there a way to make this reentrant? Thanks, S

Update: Thanks for all your suggestions, in the end I used ikegami's suggestion, as yes, it doesn't need to be recursive with that solution. Unfortunatly the DB is SQLServer, or I would use the connect by option. Thanks again, S
