Question

我们有2个选择sql查询：

SELECT id, username, group_id, score FROM users WHERE status=1 AND
active=1 AND id != 9 AND score >= 100 ORDER BY score DESC LIMIT 2;

和

SELECT id, username, group_id, score FROM users WHERE status=1 AND
active=1 AND id != 9 AND score <= 100 ORDER BY score DESC LIMIT 2;

如何通过1 sql查询选择它们？

这是一个MySQL数据库。

Answer 1

使用union all代替

(SELECT id, username, group_id, score FROM users WHERE status=1 AND
active=1 AND id != 9 AND score >= 100 ORDER BY score DESC LIMIT 2)
union all
(SELECT id, username, group_id, score FROM users WHERE status=1 AND
active=1 AND id != 9 AND score <= 100 ORDER BY score DESC LIMIT 2)

是否可以在1 sql select中选择这些查询？
