我想爲我的Azure數據庫服務器創建新的數據庫登錄名。它使用SQL管理工作室時，但不是從C＃代碼工作，我無法弄清楚是什麼問題。從代碼中創建Azure數據庫登錄引發SqlException
Azure的文檔Manage Database Logins展示瞭如何做到這一點：
-- first, connect to the master database
CREATE LOGIN login1 WITH password='<ProvidePassword>';
CREATE USER login1User FROM LOGIN login1;
EXEC sp_addrolemember 'dbmanager', 'login1User';
EXEC sp_addrolemember 'loginmanager', 'login1User';
再次 - 只要我使用SQL Management Studio中這就像一個風情萬種。現在我想從代碼做同樣的事情。請看看我的代碼：
// This is ConnectionString to master database.
// 'User ID' in this string is sa login created in Azure Portal.
var cs = "Server=tcp:XXX.database.windows.net,1433;Database=master;User [email protected];Password=XXX;Encrypt=True;TrustServerCertificate=False;Connection Timeout=240";
// SQL command
var command = "CREATE LOGIN testLogin WITH password = 'Test123!!!'";
// Execute command using cs
using (var context = new MyDataContext(cs))
{
// works fine - I am connected to the master db
context.Database.Connection.Open();
// this line throws exception
// "CREATE TABLE permission denied in database 'master'"
context.Database.ExecuteSqlCommand(command);
}
正如你可以看到我已經嘗試過1：1像文檔說的，但它不起作用。在SQL Management Studio中執行完全相同的操作只是起作用。我也嘗試過很好的SqlConnection以確保它不是由Entity Framework引起的，但不會改變任何內容。
我不知道這裏有什麼區別。我錯過了什麼嗎？任何提示？
EDIT1： 這裏是例外。
消息：
CREATE TABLE permission denied in database 'master'.

請問您可以添加例外嗎？ – Jay
MSDN上的這篇文章可能有所幫助：https：//msdn.microsoft.com/en-us/library/ms173463.aspx。這可能是因爲你使用的連接字符串只允許你訪問特定的數據庫（登錄是在SQL實例上創建的，它包含許多數據庫，包括「master」）。你可能需要一個複合語句，比如'CREATE LOGIN AbolrousHazem WITH PASSWORD ='340 $ Uuxwp7Mcxo7Khy'; USE AdventureWorks2008R2; CREATE USER AbolrousHazem FOR LOGIN AbolrousHazem; GO' – NickT
