我已經安裝與Microsoft Sync Framework同步，現在我需要將字段添加到表中。 如何重新設置數據庫？Microsoft Sync Framework - 如何在模式更改後重新配置表（或整個範圍）？
的設置是非常簡單的：
SqlSyncProvider我是否在兩端進行結構更改？或者，我是否只更換一臺服務器，並讓Sync Framework以某種方式傳播更改？
我需要刪除_tracking表和/或存儲過程嗎？觸發器怎麼樣？
有沒有人使用過Sync Framework？請幫忙。

B中的其它表的表「H ÿ你已經有了如何完全從數據庫中獲取同步MetaData的基本思路。 首先我想指出要小心。如果您有多個範圍指向相同的表。您提供的代碼將刪除範圍之間共享的觸發器，sprocs等，當您嘗試執行其他範圍時，您將遇到麻煩。 我很驚訝，這樣的功能不包括在框架中。也許作爲「社區」，我們可以組合一個實用工具，其中包括簡單的輔助方法，比如這個和我在博客上發佈的輔助方法。 – Rabbi 2010-06-16 11:56:30
接下來我想對您的編程發表點評： 1.您使用傳遞參數的反模式來顯示消息框。如果調用者知道足以傳遞該參數，那麼它應該只是自己處理UI，並在該函數返回後顯示消息框。 2.當你神奇地獲得_settings對象時，conn是一個有趣的選擇。如果可以的話，我會考慮以相反的方式來做 - 設置應該是參數（這就是你正在處理的），Conn應該通過IOC或成員變量來訪問。 – Rabbi 2010-06-16 12:06:59
3.爲什麼「USE [」+ Conn.Database + @「]」？如果您從連接中獲取數據庫的名稱。那麼它必須是連接的當前數據庫。所以這完全是多餘的。 – Rabbi 2010-06-16 12:08:48
我用Montago的解決方案，但它轉換成做了工作的SQL代碼爲了我。可以自由地使用它，我希望它可以幫助你:)

這一點，因爲你可以看到通過所有的表去，並試圖找到同步的痕跡。您只需更改數據庫名稱（第一行）。 另外，如果你想與你刪除的內容更安全，使用此代碼查找表：
-- get the next table
SELECT TOP 1
@id = object_id,
@name = REPLACE(name, '_tracking', '')
FROM sys.tables
WHERE object_id > @id
AND name LIKE '%_tracking'
ORDER BY object_id
這隻會尋找那些實際上正在同步
你可以使用這個腳本表：

set @SQL='';
