MySQL：如何从.SQL脚本文件运行shell命令

Question

Running with MySQL 5.6.36 on Windows 10, I am writing a script in .sql file. I need to run some shell command (in this case to concatenate two files).

How can i do it?

I tried this but it gives "compilation error":

\! ls

It says:

Syntax error: '\\' escape operator is not valid input at this position

Answer 1

I can't reproduce the error:

File: /path/to/file/test.sql

SELECT VERSION();

SELECT 'system' `system`;
system ls -al myDir

SELECT '\\!';
\! ls -al myDir

MySQL Command Line:

mysql> \. /path/to/file/test.sql
