本文將介紹當您安裝了 SQL Server 2012 後，如何開始使用內建的 SQL Server Data Tools。
在上一篇筆者提到可以利用 Web PI 下載 SQL Server Data Tools 來加強 Visual Studio 2010 有關 SQL Server 的各項功能，若您已安裝 SQL Server 2012 會發現，在程式集中會看到已經內建 SQL Server Data Tools，但實際上開啟 Visual Studio 2010 卻找不到 SQL Server 物件總管。
手動嘗試安裝也失敗。
詳細的錯誤訊息如下：

既然透過 Web PI 安裝失敗，筆者嘗試直接到 Data Developer Center 下載適合 SSDT 安裝程式，以筆者的環境為例，因為 Visual Studio 2010 安裝的是英文版，因此下載 English(United States) 版的安裝程式。
下載完畢之後重點在於必須先將安裝程式解除封鎖。
接著必須以系統管理員身分執行安裝作業。
最後總算安裝成功，您可以在 About Microsift Visual Studio 看到 Microsoft SQL Server Data Tools 的項目。
雖然 SQL Server 2012 看起來有內建 SQL Server Data Tools，不過實際上仍需自行到 Data Developer Center 或是透過 Web PI 下載並安裝，無法直接使用，希望本文可以對您有幫助。
