当使用FireDAC Explore 创建Mysql连接时报：[FireDAC][Phys][MySQL]-314. Cannot load vendor library [libmysql.dll or libmysqld.dll]. 系统找不到指定的文件。
Hint: check it is in the PATH or application EXE directories, and has x86 bitness.
Failed to load DBMS client !

解决：

1、下载dll。

2、复制到D:\Program Files (x86)\Embarcadero\Studio\20.0\bin

3、FireDAC Explore如下设置。
