加入 SQL Azure 的使用者

在Windows Azure的Database Service訂閱了一個SQL Azure服務後，一般來說會要求你建立一個管理者的帳號，但通常在設計系統時又不可能把這個帳號就大喇喇的拿來用在AP上面做連線，這時候就需要另外建立一組帳號，並只開放db_datawriter以及db_datareader的權限來做存取。
過去我們很習慣直接在SQL Server Management Studio以UI的方式加一加，設定一些使用者資料配置就可以了，但是連到SQL Azure上時似乎沒辦法提供這樣的模式(至少我現在用windows 2012是不行的)。於是就只好下command來執行了，方法如下：

1.  連線到master database建立一組登入權限
     CREATE LOGIN balogin WITH PASSWORD = 'xxxxxxx';

2.  連線到個別的資料庫，並建立使用者，如連到ABC資料庫後再下指令：
     CREATE USER businessadvisor FROM LOGIN balogin;

3.  附予該資料庫使用者的權限，以本例來說只開放讀寫的權限。
     EXEC sp_addrolemember 'db_datawriter', 'businessadvisor'
     EXEC sp_addrolemember 'db_datareader', 'businessadvisor'

以上指令只要改一改有底色的地方就可以了，但要記得執行時資料庫的切換。
完成後只要去再去Management Studio的Security Tag下確認一下user是否建立完成就可以了。

SQL Server2012匯出資料到SQL Azure的好用方法

最近開發好的系統要上Azure了，可是我用的是SQL Server2008，試了很多方法做匯出但老是不順，我試了幾種方式：
1.將原有資料庫schema以指令匯出後，再到SQL Azure上執行。
2.直接用Management Studio做匯入/匯出動作。
3.使用vistual studio的SSDT(SQL Server Database Tool) for visual studio 2012。
以上三個雖然可行，但就是非常不直覺，請教了公司的先進之後，
原來SQL Server2012有非常好用的匯出方式，可以快速的佈署到SQL Azure上。
其步驟如如下：
1.首先先把原有SQL Server2008的資料庫還原一份到SQL Server2012上面。
2.指定Database，並於工作中選取"Export Data-tier Application"，將指令以及資料做匯出的動作。

3.將匯出的bacpac檔匯回SQL Azure資料庫中。

4.確定SQL Azure上是不是已經多了一個資料庫，簡單！完工！

刪除自訂於資料庫,資料表以及欄位中的擴充欄位屬性

最近SQL Server2012匯出資料庫到bacpac file,準備匯入到SQL Azure時,發生以下問題
原來是因為方便讀取各欄位的描述，所以在每個欄位的Extended Properties都訂義了MS_Description屬性，本來想一個個刪，結果發現有這麼一段SP可以一次處理掉，
步驟如下：

Step1: 
執行以下執令取得各別刪除Extended Properties的指令

Step2:
執行後產出以下指令時，再一次貼回New Query視窗就可以順利刪除Extended Properties了。
