• Entity Framework Core生成的存储过程在MySQL中需要进行处理及PMC中的常用命令


    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。
