1. SQLite3语法和MySQL不完全兼容，在数据类型、默认值关键字、存储过程、索引和约束等方面均和MySQL有一定的区别，需要对比两者文档来迁移。
|
||||
2. pymysql库的接口不完全遵循Python的数据库驱动规范，存在部分功能缺失、相同接口语义不同的问题，需要重新编写这部分的代码
|
||||
3. pymysql没用SQL脚本执行功能，不能直接用python代码直接初始化数据库，需要手工导入。
|
||||
3. pymysql没有SQL脚本执行功能，且无法一次执行多条SQL语句，因此难以直接用python代码初始化数据库，需要手工导入或编写专用的读取代码。

3. 数据库自动初始化
|

我希望能够实现不需要用户手动导入SQL脚本就可以完成数据初始化。经过搜索各种博客，我发现Flask框架可以编写单独的命令用于初始化；同时我还结合网上的资料编写了解析MySQL格式的SQL脚本的代码，用于将SQL脚本转换为pymysql可以执行的语句。这样只需要用户在完成安装后执行初始化命令就可以自动完成数据库表和触发器的导入。

经过搜索文档之后，发现Flask框架自带了一个简单的登陆验证框架，可以直接使用。
