Php mysql选择具有多个WHERE的查询

我需要根据ID在一个查询中选择几行，例如下面是我写的

SELECT * FROM posts WHERE post_id = "15 , 14 , 14"

---

如何在真正的sql查询中执行此操作？

使用或/和where条件。比如：

SELECT * FROM posts WHERE post_id IN (14,15);

SELECT * FROM posts WHERE post_id = '13' OR post_id = '14' OR post_id = '15'

您还可以使用：

SELECT * FROM posts WHERE post_id BETWEEN 14 and 15

---

速度最快且效率更高的选项：

SELECT * FROM posts WHERE post_id IN (14,15) 

但是，使用说明

或
并没有错

SELECT * FROM posts WHERE post_id = 14 OR post_id = 15

SELECT * FROM posts WHERE post_id = 14 OR post_id = 15
