### DBeaver 中导入 `.sql` 文件教程 #### 设置全局 UTF-8 编码 为了防止导入过程中出现乱码，建议先设置全局编码为 UTF-8。这可以通过修改配置文件或在命令行中指定来实现[^2]。 #### 准备工作 确保已经获取到需要导入的 `.sql` 文件，并确认该文件中的 SQL 语法正确无误。如果不确定，可以提前打开文件查看并修正可能存在的问题，比如缺少分号的情况[^4]。 #### 创建目标数据库 从 `.sql` 文件中找到即将创建的数据库名称，在 DBeaver 中手动建立一个新的数据库实例，并为其设定合适的字符集（通常是 utf8mb4）以及排序规则（collation）。完成这些操作之后再继续下一步骤[^3]。 #### 导入过程 1. **连接至目标数据库** - 打开 DBeaver 并连接到之前新建的目标数据库上。 2. **加载 SQL 脚本** - 可以通过直接将 `.sql` 文件拖拽进入 DBeaver 的查询编辑器区域来进行加载；也可以点击工具栏上的 “Open File” 按钮选择本地磁盘路径下的 `.sql` 文件进行读取。 3. **执行 SQL 命令** - 加载完成后，检查一遍整个脚本的内容是否正常显示出来，特别是注意是否有遗漏掉的分隔符 `;` 。一旦确认无误，则可以直接运行此脚本来完成数据表结构及初始数据记录的构建。 - 若遇到任何报错信息，请仔细阅读错误描述并针对性地调整源代码直至成功为止。 4. **验证结果** - 当所有指令都顺利被执行后，应该能够在右侧的对象浏览器里看到新加入的数据对象列表项。如果没有立即显现的话，试着刷新一次当前会话即可。 ```sql -- 示例：简单的SQL语句片段用于测试目的 CREATE DATABASE IF NOT EXISTS test_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; USE test_db; CREATE TABLE example_table ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(50), age TINYINT UNSIGNED ); INSERT INTO example_table VALUES(NULL, 'Alice', 25), (NULL, 'Bob', 30); SELECT * FROM example_table; ```
