mysql - 尝试在命令行中使用文本文件执行 SQL 语句

Question

我对 SQL 很陌生，实际上昨天才开始。我正在关注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。这是我输入的命令以及错误消息：

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

谢谢你的帮助。

Answer 1

您需要转义反斜杠。类型source c:\\sql\\LearningSQLExample.sql;

Answer 2

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

source c:/temp/s_s.sql;
