MySQL和区分大小写的真正混乱

Question

Windows操作系统-phpMyAdmin

select auth, COUNT(*) AS count from posts where auth = 1;

提供信息：

Your SQL query has been executed successfully

但：

select auth, count(*) AS count from posts where auth = 1;

给出以下内容：

Showing rows 0 - 0 (1 total, Query took 0.0070 seconds.

在这里，我发现了一个关于MySql和区分大小写的真正令人困惑的故事。

对于每个操作系统，是否存在编写小写或大写查询的通用最佳实践，或者我必须分别学习所有规则？

Answer 1

你试过了吗：

 select auth, count(*) AS count 
 from posts 
 where auth = 1
 group by auth
 ;
