在使用Entity Framework Core生成MySQL数据库脚本，对于生成的存储过程，在执行的过程中出现错误，需要在存储过程前面添加

delimiter //

附：可以使用Visual Studio中的程序包管理器控制台执行Entity Framework Core中的迁移命令。

PMC Command	Usage
Get-Help entityframework	显示有关实体框架命令的信息。
Add-migraion <migration name>	通过添加迁移快照来创建迁移。
Remove-Migration	删除最后一个迁移快照。
Update-Database	根据上一个迁移快照更新数据库架构。
Script-Migration	使用所有迁移快照生成SQL脚本。
Scaffold-DbContext	为指定的数据库生成DbContext和实体类型类。这称为逆向工程。
Get-DbContext	获取有关DbContext类型的信息。
Drop-Database	删除数据库。
