在某些服务器中出现以下错误：

    location / {
         uwsgi_pass unix:/home/andrew/andrew-django-personal-site/personalsite/personalsite.sock;
         include /your_location/conf/uwsgi_params; // or your own
         uwsgi_modifier1 30;          // ignore extra if not used
         proxy_set_header HTTP_AUTHORIZATION $http_authorization; // only use if needed
         proxy_set_header  X-Real-IP  $remote_addr; // only use if needed
         proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;// only if needed
         proxy_set_header  Host $http_host; // only use if needed
         proxy_redirect  off;  // only use if needed
    }

的connectionString：

             string host, string port, string login, string password)
    {
        OleDbConnection connection = null;
        try
        {
            connection = Connection.GetConnection(database, host, port, login, password);
            OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connection);
            DataSet dataSet = new DataSet();
            dataAdapter.FillSchema(dataSet, SchemaType.Mapped);
            dataAdapter.Fill(dataSet);

            return dataSet.Tables[0];
        }
        finally 
        {
            Connection.CloseConnection(connection);
        }
    }

Answer 1

别忘了打开联系。

如果您只想查询和更新数据库，则不需要FillSchema。

你可以在ADO.NET中使用idb2connexion，idb2dataadapter，它更好

Example here

Answer 2

我删除了一行

dataAdapter.FillSchema(dataSet, SchemaType.Mapped);

OleDbProvider，db2，E_FAIL（0x80004005）
