Question

我有一张这样的表：

"id"    "UserName"  "score"
"1"     "User 1"    "2"
"2"     "User 2"    "5"
"3"     "User 3"    "3"
"4"     "User 4"    "7"
"5"     "User 5"    "1"

并运行这样的SQL：

select userName from stack where id >= 0 order by score DESC LIMIT 3

这给了我结果

"userName"
"User 4"
"User 2"
"User 3"

这意味着它的安排就像这样;

"id"    "UserName"  "score"
"4"     "User 4"    "7"
"2"     "User 2"    "5"
"3"     "User 3"    "3"
"1"     "User 1"    "2"
"5"     "User 5"    "1"

如何从id 1开始，并获得如下结果。因为无论我做什么，我都会得到不正确的结果：

预期结果：

select userName from stack where id >= 1 order by score DESC LIMIT 3

"1" "User 1"    "2" /*These are my expected results and not what the above query outputs*/
"5" "User 5"    "1"

这一切都来自于分页系统，我们根据分数显示用户。

Answer 1

您可以在LIMIT中使用偏移：

select userName from stack where id >= 1 order by score DESC LIMIT 3,3

对于您的分页，您必须增加每页的偏移量。

Mysql坚持使用desc和限制命令
