如何在此動(dòng)態(tài)查詢中使用日期范圍函數(shù)從數(shù)據(jù)庫(kù)中獲取數(shù)據(jù)，例如從日期到日期從數(shù)據(jù)庫(kù)中獲取數(shù)據(jù)。unset($sql);    if ($stationFilter) {        $sql[] = " STATION_NETWORK = '$stationFilter' ";    }    if ($verticalFilter) {        $sql[] = " VERTICAL = '$verticalFilter' ";    }    $query = "SELECT * FROM $tableName";    if (!empty($sql)) {        $query .= ' WHERE ' . implode(' AND ', $sql);    }    echo $query;
