52 rows in set (0.00 sec)
小迪，为什么 导入D:\software\MySql\bin>mysql -u root -p cookbook < D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql 只有52个文件，原程序有
103 rows in set (0.00 sec）
关于MySQL导入文件数量不一致的问题
您遇到的问题是：从cookbook.sql文件导入时只导入了52个表/数据，而原程序应该有103个。
可能的原因
SQL文件不完整：检查cookbook.sql文件是否完整，可能只包含了部分内容
字符编码问题：文件可能在传输或保存过程中使用了不兼容的字符编码，导致部分SQL语句无法正确解析
执行错误：导入过程中可能有部分语句执行失败，但未显示错误
文件路径问题：确认D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql确实是完整的文件
解决方案
检查文件完整性：
type D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql | find “CREATE TABLE”
统计文件中包含的CREATE TABLE语句数量
分步导入：
mysql -u root -p cookbook < D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql > import.log 2>&1
这样可以将导入过程的输出和错误保存到import.log文件中查看
使用MySQL客户端直接导入：mysql -u root -p
use cookbook;
source D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql;
这样可以实时看到执行过程中的任何错误
验证数据：
导入后执行：
SHOW TABLES;
SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = ‘cookbook’;
查看实际导入的表数量
如果您能提供导入过程中的错误信息或SQL文件的开头部分，我可以给出更具体的建议。

向小迪咨询，解决方案：
ERROR:
Unknown command ‘\M’.
ERROR:
Unknown command ‘\m’.
ERROR 1049 (42000): Unknown database ‘ecipescookbook.sql;’
从您提供的错误信息来看，导入过程中出现了几个关键问题：
问题分析
字符编码问题：
客户端字符集是GBK，而服务器使用utf8mb4
这可能导致SQL文件中的某些特殊字符被错误解析
路径解析错误：
错误显示 Unknown database ‘ecipescookbook.sql;’，表明MySQL尝试将您的SQL文件名的一部分当作数据库名
转义字符问题：
\M 和 \m 被当作MySQL命令，但实际可能是文件中的内容
解决方案
统一字符集：
sql
SET NAMES utf8mb4;
在导入前先执行这条命令，确保客户端、连接和结果使用一致的字符集
使用完整路径的正确格式：
Windows路径中的反斜杠需要转义或改为正斜杠：
sql
source D:/sql/MySQL_cookbook/mysqlcookbook-master/recipes/cookbook.sql
或
sql
source D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql
检查文件内容：
用文本编辑器打开SQL文件，检查开头部分是否有异常内容或特殊字符
尝试替代导入方法：
bash
mysql -u root -p cookbook --default-character-set=utf8mb4 < “D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql”
分块导入：
如果文件很大，可以尝试用文本编辑器分割成多个小文件分别导入
您能否提供SQL文件的开头几行内容？这样我可以更准确地判断问题所在。

根据您提供的SQL文件开头内容，这是一个由MySQL 8.0.27的pump工具创建的完整数据库转储文件。结合之前的错误信息，以下是解决方案：
问题根源
字符集冲突：
文件指定了utf8mb4但客户端使用gbk
导致特殊字符和转义序列被错误解析
Windows路径问题：
反斜杠被解释为转义字符
客户端版本差异：
转储文件来自8.0.27(Linux)，您使用的是8.0.40(Windows)
完整解决方案
方法1：使用命令行导入（推荐）
cmd
mysql -u root -p --default-character-set=utf8mb4 cookbook < “D:\sql\MySQL_cookbook\mysqlcookbook-master\recipes\cookbook.sql”
方法2：在MySQL客户端中正确导入
先连接到MySQL：cmd
mysql -u root -p --default-character-set=utf8mb4
然后执行：sql
SET NAMES utf8mb4;
USE cookbook;
SOURCE D:/sql/MySQL_cookbook/mysqlcookbook-master/recipes/cookbook.sql;
方法3：修复环境变量
如果仍有问题，临时修改客户端字符集：
cmd
chcp 65001
mysql -u root -p --default-character-set=utf8mb4
重要提示
确保cookbook数据库不存在或可以覆盖：
sql
DROP DATABASE IF EXISTS cookbook;
CREATE DATABASE cookbook CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci;
如果文件很大(>100MB)，建议使用：
cmd
mysql -u root -p --max_allowed_packet=512M --default-character-set=utf8mb4 cookbook < “sql文件路径”
检查文件完整性：
确保文件没有在Windows编辑器中意外被保存为UTF-8 with BOM格式
用十六进制编辑器检查文件开头是否有EF BB BF序列(BOM标记)
请尝试以上方法后告知结果，如果仍有问题，可能需要检查文件传输过程中是否损坏（比对MD5校验值）。
