	void dbInsert(string login, string uploading_date, string 
geometry_type, string data)
	{
	
	    Statement stmt = conn.createStatement();
		string sqlinsert = (`INSERT INTO usersshapes (userlogin, 
uploading_date, geometry_type, data) VALUES ('%s', '%s', '%s', 
'%s') `, login, uploading_date, geometry_type, data);
		stmt.executeUpdate(sqlinsert);
		scope(exit) stmt.close(); // closing
	}
