自動生成數據庫字典(sql2008)

每次做項目的時候都要做數據字典，這種重復的工作實在很是痛苦，于是廣找資料，終于完成了自動生成數據庫字典的工作，廢話少說，上代碼。

　當然這些通過PRING出來的代碼使用傳統的方式是調用不到的，通過查找資料，終于在國外一個XXX網站找到了解決方案。

private static string message = "";

public static string ExecuteNonQuery(string connextionString, CommandType commandType, string commandText, bool outputMsg)

{

if (connextionString == null || connextionString.Length == 0) throw new ArgumentNullException("connectionString");

// Create & open a SqlConnection, and dispose of it after we are done

using (SqlConnection connection = new SqlConnection(connextionString))

{

message = "";

connection.Open();

connection.InfoMessage += delegate(object sender, SqlInfoMessageEventArgs e)

{

message += "\n" + e.Message;

};

// Call the overload that takes a connection in place of the connection string

if (connection == null) throw new ArgumentNullException("connection");

// Create a command and prepare it for execution

SqlCommand cmd = new SqlCommand(commandText, connection); ;

cmd.CommandType = commandType;

// Finally, execute the command

int retval = cmd.ExecuteNonQuery();

// Detach the SqlParameters from the command object, so they can be used again

cmd.Parameters.Clear();

connection.Close();

return message;

}

　　調用就不用寫了嘛。一切就這么簡單，生成的是一份標準的htm代碼，可直接放到HTML里面，當然也可以直接從數據庫讀取出來顯示。
