尝试在命令行中使用文本文件执行SQL语句

Question

我对SQL很新，实际上昨天刚开始。我跟随的书要求我从他们提供的文本文件中运行sql语句。但是，我收到一条错误消息，我不明白为什么。以下是我输入的命令以及错误消息：

 mysql> use bank;
Database changed
mysql> source c:\sql\LearningSQLExample.sql;

感谢您的帮助。

Answer 1

你需要逃避反斜杠。输入source c:\\sql\\LearningSQLExample.sql;

Answer 2

对于较新版本的mySQL命令行，只是一个额外的解决方案 将LearningSQLExample.sql文件重命名为包含下划线的文件。 比如s_s.sql然后在命令行尝试

source c:/temp/s_s.sql;
