Question

我被告知，我的数据库设置错误很可能导致问题，所以下面的表格包含关键字段和查询。

CREATE TABLE Presentations (
    Id INT NOT NULL IDENTITY(1, 1),
    SpeakerId INT NOT NULL,

    CONSTRAINT PK_Presentations PRIMARY KEY (Id),
    CONSTRAINT FK_Presentations_Speaker FOREIGN KEY (SpeakerId) REFERENCES Speakers (Id)
)

CREATE TABLE Speakers (
    Id INT NOT NULL IDENTITY(1, 1),

    CONSTRAINT PK_Speakers PRIMARY KEY (Id)
)

执行以下操作时：

presentations = presentations.OrderBy(x => x.Speaker.FirstName);

生成的查询如下所示：

SELECT  [t0].[Description], [t0].[EventId], [t0].[Id], [t0].[PresentedOn], 
        [t0].[Slug], [t0].[SpeakerId], [t0].[Title], [t0].[Url]
FROM    [Presentations] AS t0
LEFT    OUTER JOIN [Speakers] AS t1 ON ([t1].[Id] = [t0].[Id])
WHERE   ([t1].[FirstName] LIKE 'B' + '%')
ORDER   BY [t1].[FirstName]

联接应该是：

LEFT    OUTER JOIN [Speakers] AS t1 ON ([t1].[Id] = [t0].[SpeakerId])

这是一个迫切的问题，任何人都可以帮忙吗？

生成的SubSonic3 SimpleRepository关系是错误的
