如何在具有 Sql 服务器生产者的 CodeFluent 实体中的多对多关系 table 上声明聚簇键
How can I declare a Clustered key on a many-to-many relationship table in CodeFluent Entities with Sql Server Producer
我有一个 CodeFluent 实体模型，例如：
<cf:project defaultNamespace="S5T" xmlns:cf="http://www.softfluent.com/codefluent/2005/1" xmlns:cfx="http://www.softfluent.com/codefluent/modeler/2008/1" xmlns:cfmy="http://www.softfluent.com/codefluent/producers.mysql/2012/1" xmlns:cfom="http://www.softfluent.com/codefluent/producers.model/2005/1" xmlns:cfasp="http://www.softfluent.com/codefluent/producers.aspnet/2011/1" xmlns:cfaz="http://www.softfluent.com/codefluent/producers.sqlazure/2011/1" xmlns:cfps="http://www.softfluent.com/codefluent/producers.sqlserver/2005/1" defaultKeyPropertyTypeName="long" maxParameterNameLength="62" defaultConcurrencyMode="None" persistencePropertyNameFormat="{1}" defaultMethodAllowDynamicSort="false" defaultProducerProductionFlags="Default, Overwrite, RemoveDates" defaultMethodDistinct="false" createDefaultMethodForms="true" createDefaultApplication="false" createDefaultHints="false" productionFlags="Default, Overwrite, RemoveDates">
<cf:import path="Default.Surface.cfp" />
<cf:producer name="SQL Server" typeName="CodeFluent.Producers.SqlServer.SqlServerProducer, CodeFluent.Producers.SqlServer">
<cf:configuration produceViews="true" targetDirectory="..\Model7Bom\Persistence" connectionString="Server=MY-MACHINE\SQLEXPRESS;Database=model7;Integrated Security=true;Application Name=S5T;Password=MyPassword;User ID=MyUser" cfx:targetProject="..\Model7Bom\Model7Bom.vbproj" cfx:targetProjectLayout="Update, DontRemove" />
</cf:producer>
<cf:entity name="User" namespace="S5T">
<cf:property name="Id" key="true" cfps:hint="CLUSTERED" />
<cf:property name="Name" />
<cf:property name="Roles" typeName="{0}.RoleCollection" relationPropertyName="Users" />
</cf:entity>
<cf:entity name="Role" namespace="S5T">
<cf:property name="Id" key="true" cfps:hint="CLUSTERED" />
<cf:property name="Name" />
<cf:property name="Users" typeName="{0}.UserCollection" relationPropertyName="Roles" />
</cf:entity>
</cf:project>
我可以在 cfps:hint="CLUSTERED" 的两个实体上成功装饰 cf:属性 name="Id"。这让我 Sql 服务器生产者正确输出
CONSTRAINT [PK_Use_Id_Use] PRIMARY KEY CLUSTERED
CONSTRAINT [PK_Rol_Id_Rol] PRIMARY KEY CLUSTERED
与默认 NONCLUSTERED 相反。
如何使用模型生成的第三个 TABLE 来适应多对多关系？
默认情况下，table 创建生成的片段如下：
CREATE TABLE [dbo].[Role_Users_User_Roles] (
[Id] [bigint] NOT NULL,
[Id2] [bigint] NOT NULL,
CONSTRAINT [PK_Roe_Id_Id2_Roe] PRIMARY KEY NONCLUSTERED
(
[Id],
[Id2]
) ON [PRIMARY]
)
但是，如果我用 cfps:hint="CLUSTERED" 装饰两个属性，如：
cf:属性 name="Roles" typeName="{0}.RoleCollection" relationPropertyName="Users" cfps:hint="CLUSTERED" /
cf:属性 name="Users" typeName="{0}.UserCollection" relationPropertyName="Roles" cfps:hint="CLUSTERED" /
我在 TABLE [dbo].[Role_Users_User_Roles] 中得到了使用 PRIMARY KEY CLUSTERED 为 PK 生成的片段，但是，此外，我得到了不正确脚本的意外效果generated 用于添加关系（generated filename ...relations_add.sql），如：
ALTER TABLE [dbo].[Role_Users_User_Roles] WITH NOCHECK ADD CONSTRAINT [FK_Roe_Id_Id_Rol] FOREIGN KEY (
[Id]
) REFERENCES [dbo].[Role](
[Id]
) CLUSTERED
连同来自 Sql 服务器的错误：
错误 3 SQL80001：'CLUSTERED' 附近的语法不正确。
并且 CodeFluent Producer 错误：
CodeFluentRuntimeDatabaseException: CF4116: 在第 2 行执行文件...路径..._relations_add.sql 语句
我需要生成的三个 table 中的所有三个 PK，但不需要生成关系的语法错误的副作用。
不支持out-of-the-box。在 a 关系上声明的提示很少使用，更多的是作为外键提示而不是列提示。您可以使用多个选项来执行此操作。
最简单的方法是使用 post-generation .SQL 脚本手动添加集群设置。此处对此进行了描述：How to: Execute custom T-SQL scripts with the Microsoft SQL Server producer.
您还可以使用 Patch Producer 在文件创建后从文件中删除 CLUSTERED 单词：Patch Producer
否则，这是另一个解决方案，涉及我在此处作为示例编写的方面。您可以将以下片段 XML 保存为文件，并将其作为模型中的一个方面进行引用。
此方面会将 CLUSTERED 提示添加到从具有 CLUSTERED 键的实体推断出的所有多对多 table 的主键。它将在创建 table 脚本和 运行 之前添加提示，并在之后将其删除（因此它不会在 relations_add 脚本中结束）。
