Question

我正在运行MYSQL 5.5版，我收到以下错误。我已尝试将LIMIT 1添加到最后，删除ORDER BY DESC指定按DATE(submit_date)排序...但仍然收到相同的错误。

您的SQL语法有错误;检查与MySQL服务器版本对应的手册，以便在第1行的“ORDER BY DESC”附近使用正确的语法

function getApplicationStatus($userId) {
    $SQLString = "SELECT status, DATE(submit_date) FROM ". $GLOBALS['TABLES']['APPLICATION'] ." WHERE fk_userid = $userId ORDER BY DESC";
    $results = mysqli_query($GLOBALS['DB']['CONNECT'], $SQLString) or die("Error: ".mysqli_error($GLOBALS['DB']['CONNECT']));
    $data = mysqli_fetch_array($results);
    return $data['status'];
}

Answer 1

您在订单中缺少一个字段：ORDER BY DESC

添加字段：ORDER BY someField DESC或删除ORDER BY DESC文字。

Answer 2

您应该指明column_name。

SQL ORDER BY语法：

SELECT column_name, column_name
 FROM table_name
 ORDER BY column_name ASC|DESC, column_name ASC|DESC;

Answer 3

试试这个。 $ SQLString =＆＃34; SELECT状态，DATE（submit_date）FROM＆＃34;。 $ GLOBALS [＆＃39; TABLES＆＃39;] [＆＃39; APPLICATION＆＃39;]。＆＃34;在哪里fk_userid = $ userId ORDER BY＆＃39; submit_date＆＃39; DESC＆＃34 ;;

SQL语法错误按DESC排序
