PHP/MySQLi : SET lc_time_names and DATE_FORMAT() into a mysqli query?

Question

我使用下一个代码从数据库中的表中检索数据:

$check_sql = 'SELECT personID, name, DATE_FORMAT(persons.birthdate, "%d de %M, %Y"), birthplace, countryID FROM persons WHERE personID = ?';
    if ($stmt->prepare($check_sql)) {
        $stmt->bind_param('i', $pid);
        $stmt->bind_result($personDB, $name, $birthdate, $birthplace, $countryID);
        $stmt->execute();
        $stmt->fetch();
    }

如您所见，同时我使用 DATE_FORMAT() MySQL 函数将“生日”列中的日期格式化为更友好的显示。现在，我想用西类牙语显示月份全名，所以我想在查询中插入 SET lc_time_names = 'es_ES'..

我该怎么做？？？我可以将 SET lc_time_names 添加到 $check_sql 变量吗？？

谢谢!!

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$mysqli->query("SET lc_time_names = 'es_ES'");
$check_sql = 'SELECT personID, name, DATE_FORMAT(persons.birthdate, "%d de %M, %Y"), birthplace, countryID FROM persons WHERE personID = ?';
        if ($stmt = $mysqli->prepare($check_sql)) {
                $stmt->bind_param('i', $pid);
                $stmt->bind_result($personDB, $name, $birthdate, $birthplace, $countryID);
                $stmt->execute();
                $stmt->fetch();
        }
