我们，我想获得我桌子的最新5位用户。我已经尝试过这样做：

$sql = "SELECT * FROM members ORDER BY username DESC LIMIT5";

但是..不检索任何结果..

Answer 1

查询应为

$sql = "SELECT * FROM members ORDER BY username DESC LIMIT 5";

LIMIT和5之间需要空格

Answer 2

如果你想要最后5个订单应该是id / creation_time

$sql = "SELECT * FROM members ORDER BY id DESC LIMIT 5";
$sql = "SELECT * FROM members ORDER BY creation_time DESC LIMIT 5";

通过desc获取最近5位用户数据
