我正在嘗試創建一個查詢來訪問單個服務器上的多個數據庫。我正在使用遊標訪問運行查詢的基本服務器的多個其他鏈接服務器。那我遇到的問題是：服務器主體「用戶」無法在當前安全上下文中訪問數據庫「金屬」
Msg 916, Level 14, State 1, Line 43
The server principal "USER" is not able to access the database "Metals" under the current security context.
Msg 3930, Level 16, State 1, Line 104
The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.
Msg 916, Level 14, State 1, Line 43

服務器表明，我登錄了，爲什麼用「USER」和「用戶」的數據庫，以嘗試訪問「金屬」分貝？
我相信訪問Metals數據庫的查詢是正確的，因爲它在動態sql代碼之外運行時會返回正確的數據。我認爲這個問題與權限有關，但我不確定應該爲用戶更改哪些權限。目前，BLUser只具有連接和選擇權限。是否還有其他權限需要添加以允許他們訪問Metals數據庫？
查詢如下：

，我在網上找到的現有解決方案，所有列出here並沒有爲我的工作，要麼。這個one尤其沒有意義，因爲我沒有在對象資源管理器詳細信息的左列中看到數據庫作爲選項。
任何幫助解決這個問題將不勝感激！
