Question

我正在使用sql server 2008，遵循最新约定我使用除[dbo]之外的新架构。[tablename]现在看起来像这个[newdbo]。[tablename]。现在的问题是，SimpleRepository无法找到[newdbo]。[tablename]，我认为它正在寻找[dbo]而不是[newdbo]，因为我的类被定义为：

这是我的表：架构/所有者是“亲吻”

CREATE TABLE [kiss].[Users](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [UserName] [nvarchar](20) NOT NULL,
    [UserPassword] [varbinary](128) NULL,
    [UserTypeID] [tinyint] NOT NULL,
    [ByPassAccessRestrictionsFlag] [bit] NOT NULL,
    [IsEnforcePasswordPolicy] [bit] NOT NULL,
    [PasswordExpirationDate] [datetime] NULL,
    [IsPwdChangeNextLogin] [bit] NOT NULL,
    [ShowLatestNewsFlag] [bit] NOT NULL,
    [SortRowNumber] [int] NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
    [CreatedBy] [nvarchar](20) NOT NULL,
    [UpdatedDate] [datetime] NOT NULL,
    [UpdatedBy] [nvarchar](20) NOT NULL,
    [DeletedDate] [int] NULL,
    [eCrewID] [varchar](10) NULL,
    [EntityTypeID] [int] NOT NULL
)
GO

这是我的班级：

public class Users
{
    public Int32 ID { get; set; }
    public String UserName { get; set; }
    public Byte[] UserPassword { get; set; }
    public Byte UserTypeID { get; set; }
    public Boolean ByPassAccessRestrictionsFlag { get; set; }
    public Boolean IsEnforcePasswordPolicy { get; set; }
    public DateTime PasswordExpirationDate { get; set; }
    public Boolean IsPwdChangeNextLogin { get; set; }
    public Boolean ShowLatestNewsFlag { get; set; }
    public Int32 SortRowNumber { get; set; }
    public DateTime CreatedDate { get; set; }
    public String CreatedBy { get; set; }
    public DateTime UpdatedDate { get; set; }
    public String UpdatedBy { get; set; }
    public Int32 DeletedDate { get; set; }
    public String eCrewID { get; set; }
    public Int32 EntityTypeID { get; set; }
}

运行一个简单的代码：

   var repo = new SimpleRepository("kiss", SimpleRepositoryOptions.None);
   var users = repo.All<Users>();
   gvUsers.DataSource = users;
   gvUsers.DataBind();

产生错误：

Answer 1

您登录的默认架构是什么？不幸的是，你的对象无法知道你正在使用什么模式 - 这是app ---＆gt; db记住，所以如果你有一个单独的模式，你应该使用默认使用该模式的登录。

Answer 2

有两个选项

首先，获取最新的源代码，并修改源代码

找到SchemaAttributes.cs，添加代码：

[AttributeUsage（AttributeTargets.Class）] 公共类SubSonicTableSchemaAttribute：Attribute { public SubSonicTableSchemaAttribute（字符串架构） { Schema = schema; }
```
public string Schema { get; set; }
```
}
将SubSonicTableSchemaAttribute绑定到用户类

[SubSonic.SqlGeneration.Schema.SubSonicTableSchema（ “吻”）] 公共类用户{...}
查找Objects.cs文件，将代码添加到“public static ITable ToSchemaTable（此Type type，IDataProvider provider）”方法

var typeAttributes = type.GetCustomAttributes（）; foreach（typeAttributes中的var typeAtt） { 如果（typeAtt.ToString（）。等于（ “SubSonic.SqlGeneration.Schema.SubSonicTableSchemaAttribute”）） { var schema =（SubSonicTableSchemaAttribute）typeAtt; result.SchemaName = schema.Schema; } }

其次，看看我的演示： Use subsonic 3.0 SimpleRepository to a existing database

SubSonic 3.0.0.2/3 | SimpleRepository
