使用MySQL php选择除三个以外的所有行

Question

我试图使用select语句来获取某个MySQL表中的所有行，除了在user_id为5,6,7的三个中。下面是代码，但它无法正常工作。请帮忙。

$sql = "SELECT * FROM login ORDER BY user_id ASC LIMIT 0, 20 WHERE user_id<>5,6,7";

Answer 1

您必须对多个ID使用 NOT IN 功能。

$sql = "SELECT * FROM login WHERE user_id NOT IN (5,6,7) ORDER BY user_id ASC LIMIT 0, 20"

Answer 2

$sql = "SELECT * FROM login WHERE user_id<>5 ORDER BY user_id ASC LIMIT 0, 20 "

查看Order by，Where Clause和Order of operations

正如您刚刚更改了您的问题，新答案是

$sql = "SELECT * FROM login WHERE user_id NOT IN (5,6,7) ORDER BY user_id ASC LIMIT 0, 20 "

查看NOT IN

Answer 3

这样做：

 SELECT * FROM login WHERE NOT user_id = 5, ORDER BY user_id ASC LIMIT 0, 20

Answer 4

试试这个：

$sql = "SELECT * FROM `login` WHERE `user_id` NOT IN (5,6,7) ORDER BY `user_id` ASC LIMIT 0, 20";
