我收到这个错误。打开 classdiagram.cd 文件时

使用以下命令手动创建 classdiagram.cd 文件：

<ClassDiagram MajorVersion="1" MinorVersion="1">   
  <Font Name="Segoe UI" Size="9" /> 
</ClassDiagram>

我正在尝试使用 Dapper Extensions 进行 CRUD 操作。但是在将数据插入 MySQL 数据库时出现错误，如下所示：

错误：您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以获取在 [....] 行附近 [......] 使用的正确语法
