How do I reset dataset (statement handle) pointer?

[rupert]

I need to find a function or method that will reset or seek the
dataset handle back to the beginning so I can fetchrow all over again
without doing execute() functions all the time...

[code]
$dbConnection->{FetchHashKeyName} = "NAME_lc";
$dataGrid = $dbConnection->prepare("SELECT field, type FROM list");
$dataGrid->execute();

for($i=0; $i<3; $i++){

        while ($fieldRow = $dataGrid->fetchrow_hashref()) {
                print $fieldRow->{'field'};
        }

        #Nee to seek back to first row in $dataGrid here;
        $dataGrid->seekBackToFirstRow(); #I need a function to do it here...
        #fails because no such method exists to do above
}
$dataGrid->finish();
[/code]
