Question

我是nhibernet的新手，并试图创建一个测试程序。因此，我按照以下说明为Fluent NHibernate创建了实体和映射文件：https://github.com/FluentNHibernate/fluent-nhibernate/wiki/Getting-started

实体：

namespace NHibernateDemoApp
{
    public class Employee
    {
        public virtual int Id { get; protected set; }
        public virtual string FirstName { get; set; }
        public virtual string LastName { get; set; }
    }
}

地图：

class EmployeeMap : ClassMap<Employee>
{
    public EmployeeMap()
    {
        Id(x => x.Id);
        Map(x => x.FirstName);
        Map(x => x.LastName);
    }
}

然后我像这样使用它们：

private static ISessionFactory CreateFluidSessionFactory()
{
    return Fluently.Configure()
      .Database(MsSqlConfiguration.MsSql2012.ConnectionString("Data Source=mydatabase;Initial Catalog=mydatabase;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False")
      )
      .Mappings(m =>
        m.FluentMappings.AddFromAssemblyOf<Program>())
       .ExposeConfiguration(BuildSchema)
      .BuildSessionFactory();
}

private static void BuildSchema(Configuration config)
{
    new SchemaExport(config)
      .Create(false, true);
}

一切都很好，但是NHibernet创建了以我的用户名作为前缀的表。因此，表创建如下所示：

CREATE TABLE [MyDomain\MyUsername].[Employee](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [FirstName] [nvarchar](255) NULL,
    [LastName] [nvarchar](255) NULL,
PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

但是应该这样创建：

CREATE TABLE [MyDatabase].[Employee](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [FirstName] [nvarchar](255) NULL,
    [LastName] [nvarchar](255) NULL,
PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

当我以另一个用户身份启动测试程序时，该表将被创建两次（每个用户一个）。

我做错了什么？如何告诉hibernet在表创建中应该没有用户名。

您需要更改默认架构。这是NH配置设置。确保您具有数据库权限，可以在dbo模式中创建表。

您应该能够执行以下操作：

return 
    Fluently.Configure()
        .Database(
            MsSqlConfiguration.MsSql2012
                .ConnectionString("Data Source=mydatabase;Initial Catalog=mydatabase;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFai9lover=False")
                .DefaultSchema("dbo"))
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>())
        .ExposeConfiguration(BuildSchema)
        .BuildSessionFactory();

该选项挂起配置类型：https://github.com/FluentNHibernate/fluent-nhibernate/wiki/Database-configuration
