php - How to select MYSQL Content with between Date

How can I display values from the database of the Stand column with the help of the Datum column between two dates?

I tried the following code, but no result:

$sqlAverage10 = "SELECT Stand FROM Aktienstand WHERE Symbol=:symbol AND Datum BETWEEN :startDate AND :endDate10";
                    if ($stmtAverage10 = $pdo->prepare($sqlAverage10)) {
                        $stmtAverage10->execute(array(

                            ':symbol' => $kurs['Symbol'],
                            ':startDate' => $startDate,
                            ':endDate10' => $endDate10
                        ));
                        //var_dump($kurs['Datum']);
                        //var_dump ($stmtAverage10);
                        //echo ($startDate = $kurs['Datum']);
                        $stmtAverage10New = $stmtAverage10->fetch(PDO::FETCH_ASSOC);

:symbol = test :startDate = 2021-10-09 :endDate = 2021-09-29

Solution:

That should work as long as your column is a date or datetime column.
