我建議你在每張表中使用2列。名稱rowhistory和IsDeleted和數據類型將xml和位。 永遠不要刪除行，總是使用標誌IsDeleted 現在去更新觸發器。我會給你比如對同一 我有這叫做頁
CREATE TABLE te_Page([Id] [int] IDENTITY(1,1) NOT NULL, [Name] [varchar](200) NOT NULL, [Description] [varchar](200) NULL,[CreatedBy] [uniqueidentifier] NULL, [CreatedDate] [datetime] NOT NULL, [UpdatedBy] [uniqueidentifier] NULL, [UpdatedDate] [datetime] NULL, [IsDeleted] [bit] NULL, [RowHistory] [xml] NULL, CONSTRAINT [PK_tm_Page] 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]
一個表現在創建表，所有你需要做的就是複製粘貼下面的代碼，你的任務是爲頁表完成之後。它將開始在與舊值和新值一起更新的同一行中記錄行的歷史記錄。

現在只要您將執行你的數據將存儲在rowhistory列的任何更新
我看不出它抓住了用戶ID - 它必須是因爲已登錄的地方注入在用戶數據庫中不匹配。 – dkretz 2008-11-18 20:17:37
