我是新手。我正在下载一个巨大的 mysql 数据库示例用于学习目的。使用 mysql 工作台，当我打开上面的脚本时，它将突出显示所有“source load_******.dump;”语句，出现错误“语法错误：'源'（源）在此位置无效输入”。有人可以帮我解决这个问题吗？

顺便说一句，我从以下位置下载此数据库：https://github.com/datacharmer/test_db

您可以使用 

MySQL Workbench
运行脚本。

转到文件 -> 运行 SQL 脚本...

选择您要运行的文件（*.sql）。然后您会看到如下屏幕。

点击运行按钮。它根据脚本创建架构并导入表和数据。

source
命令不是MySQL语句，而是仅由MySQL客户端处理的东西。 MySQL Workbench 不处理这个问题（因为它专注于纯 MySQL 代码）。

要导入整个集合，请从主文件中删除源命令，然后像处理主转储一样手动导入这些文件。有点乏味，但至少有一种加载所有文件的方法。

删除以下行，因为它尝试导入其他文件

SELECT 'LOADING departments' as 'INFO';
source load_departments.dump ;
SELECT 'LOADING employees' as 'INFO';
source load_employees.dump ;
SELECT 'LOADING dept_emp' as 'INFO';
source load_dept_emp.dump ;
SELECT 'LOADING dept_manager' as 'INFO';
source load_dept_manager.dump ;
SELECT 'LOADING titles' as 'INFO';
source load_titles.dump ;
SELECT 'LOADING salaries' as 'INFO';
source load_salaries1.dump ;
source load_salaries2.dump ;
source load_salaries3.dump ;

source show_elapsed.sql ;

或者从命令行导入

mysql -u username -p database_name < file.sql

确保以下文件应位于同一文件夹中

load_departments.dump 
load_employees.dump 
load_dept_emp.dump 
load_dept_manager.dump 
load_titles.dump 
load_salaries1.dump 
load_salaries2.dump 
load_salaries3.dump 
show_elapsed.sql

我今天也遇到这个问题了。在尝试了上述所有方法后仍然遇到错误，我决定下载较旧的 MySQL Workbench 版本，并且一切正常！

当前最新版本：8.0.24 我下载的版本：8.0.20

还是不知道为什么会这样。

在 MySQL Workbench 中通过文件 -> 运行 SQL 脚本...进行导入似乎与其他进程使用的文件存在一些问题。

就我而言，通过命令行导入是有效的。

cd "path/to/test-db"
mysql -u root < employees.sql

如果没有找到

mysql
，则说明你的mysql二进制文件夹未存储在PATH环境变量中。您可以将“C:\Program Files\MySQL\MySQL Server X.X in\mysql.exe”添加到 PATH 或运行

cd "path/to/test-db"
"C:\Program Files\MySQL\MySQL Server X.X\bin\mysql.exe" -u root < employees.sql

其中 X.X 是您的 MySQL 服务器版本。

我遇到了同样的问题，通过观看此视频解决了：https://www.youtube.com/watch?v=-ksz8J6FQ0A

基本上，您可以使用命令提示符来安装员工数据库:)
