一對多反身關聯INSERT數據

Question

我有一個表與一對多反身關聯。

我需要插入第一個禁用臨時約束的值。 任何想法如何做到這一點？

我使用MS SQL 2008，謝謝你們的支持！

CREATE TABLE dbo.CmsCategories 
    (
     CategoryId  int    NOT NULL IDENTITY (0,1) -- Seed = 0 and Increment= 1 
      CONSTRAINT PK_CmsCategories_CategoryId PRIMARY KEY, 
     ParentOf  int    NOT NULL 
      CONSTRAINT DF_CmsCategories_ParentOf DEFAULT 0 
    ); 
ALTER TABLE dbo.CmsCategories 
ADD CONSTRAINT FK_CmsCategories_ParentOf FOREIGN KEY (ParentOf) REFERENCES dbo.CmsCategories(CategoryId); -- One-to-many Reflexive association 
GO 

    INSERT INTO dbo.CmsCategories 
    (ParentOf) 
    VALUES 
    (0);

我發現瞭解決方案，告訴我你怎麼看，謝謝！

-- CmsCategories: Disable constraint one-to-many reflexive association to add first row 
    ALTER TABLE dbo.CmsCategories 
    NOCHECK 
    CONSTRAINT 
    FK_CmsCategories_ParentOf; 

    ---- CmsCategories: Insert first row - Root value 
    INSERT INTO dbo.CmsCategories 
    (Title, MetaDescription, MetaKeyword, Summary, IsPublished, ParentOf) 
    VALUES 
    ('Homepage','Homepage','Homepage','Homepage',1,0); 

    -- CmsCategories: Enable constraint one-to-many reflexive association 
    ALTER TABLE dbo.CmsCategories 
    CHECK 
    CONSTRAINT 
    FK_CmsCategories_ParentOf;
