未能CREATE TABLE在SQL Azure數據庫使用SMO

Question

由於USE [dbname]沒有在SQL Azure的支持，我想通過在連接字符串中指定數據庫名稱，然後執行CREATE TABLE...腳本連接到我的SQL Azure數據庫。但是，這會失敗，並且System.Data.SqlClient.SqlException 「CREATE TABLE權限在數據庫'master'中被拒絕。」我在這裏做錯了什麼，它試圖對主人執行這個聲明？

下面是一個簡單的C＃代碼：

 
string connectionString = @"Data Source=tcp:MYSERVER.database.windows.net;Initial Catalog=MYDATABASE;Integrated Security=False;User ID=USER@MYSERVER;Password=PWD;Connect Timeout=60;Encrypt=True;TrustServerCertificate=True";
 

using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); ServerConnection serverConnection = new ServerConnection(connection); Server server = new Server(serverConnection); server.ConnectionContext.ExecuteNonQuery("CREATE TABLE New (NewId int)"); } 

Answer 1

原來有與代碼我有多個問題。當涉及到SQL Azure時，SMO仍然非常古怪。所以，張貼我的調查結果，以防有人正在經歷同樣的岩石之路。

1. SMO每次你得到的時間切換幕後的默認數據庫的數據庫對象是這樣的：

   
   Database database = server.Databases[databaseName] 
   

   初始目錄成爲大師，你可以看到它是改變server.ConnectionContext.ConnectionString連接字符串中（「正常」的SQL不這樣做）。解決方法是每次數據庫切換到Master時打開一個新的連接（並關閉舊的連接），因爲一旦建立連接（顯然，只有SQL Azure可以實現），數據庫名稱才能被更改。
2. 打開與ServerConnection和Server進行初始化的連接有時會與第一個問題一起失敗。這會給出一個模糊的錯誤消息，指出登錄失敗，並提供聯繫客戶支持的GUID和時間戳。廢話。對於此問題的解決是不打開連接，讓一個ServerConnection服務器對象的初始化過程中打開它：
3. 最後，阿爾特（）不是通過SQL Azure的服務器對象的喜歡。刪除了所有Alter的。

所以最終的代碼片段看起來是這樣的：

     string connectionString = "Server=tcp:XXXXX.database.windows.net;Database=XXXXXX;User ID=XXXXXX;Password=XXXXX;Trusted_Connection=False;Encrypt=True;trustservercertificate=true"; 
     SqlConnection connection = new SqlConnection(connectionString); 
     // do not explicitly open connection, it will be opened when Server is initialized 
     // connection.Open(); 

     ServerConnection serverConnection = new ServerConnection(connection); 
     Server server = new Server(serverConnection); 

     // after this line, the default database will be switched to Master 
     Database database = server.Databases["MyDatabase"]; 

     // you can still use this database object and server connection to 
     // do certain things against this database, like adding database roles 
     // and users  
     DatabaseRole role = new DatabaseRole(database, "NewRole"); 
     role.Create(); 

     // if you want to execute a script against this database, you have to open 
     // another connection and re-initiliaze the server object 
     server.ConnectionContext.Disconnect(); 

     connection = new SqlConnection(connectionString); 
     serverConnection = new ServerConnection(connection); 
     server = new Server(serverConnection); 
     server.ConnectionContext.ExecuteNonQuery("CREATE TABLE New (NewId int)"); 

這裏是點＃2的情況下，有人隱晦的例外是興趣：

Answer 2

只是一個瘋狂的猜測，基於恰好適合我的連接字符串。

您是否嘗試過使用

數據庫= MYDATABASE

到位

初始目錄的= MYDATABASE

在連接字符串？

還有一件事情幫助我 - ServerConnection應該爲每個操作斷開連接。

using (var connection = new SqlConnection(parameters.ConnectionStringToMasterDatabase)) 
      { 
       var serverConnection = new ServerConnection(connection); 
       try 
       { 
        var server = new Server(serverConnection); 
        // do something 
       } 
       finally 
       { 
        serverConnection.Disconnect(); 
       } 
      } 
using (var connection = new SqlConnection(parameters.ConnectionStringToMasterDatabase)) 
      { 
       var serverConnection = new ServerConnection(connection); 
       try 
       { 
        var server = new Server(serverConnection); 
        // do something else 
       } 
       finally 
       { 
        serverConnection.Disconnect(); 
       } 
      }
