Question

I checked the parameters, and fields, nothing is mispelled,But I still get that error..

        StringBuilder sb = new StringBuilder();
    sb.Append("SELECT u.Name,t.ThreadTitle,t.Date, t.Views,t.Replies,p.Theme,p.Topics,t.PageNumber");
    sb.Append("FROM Users AS u");
    sb.Append("INNER JOIN Threads AS t ON u.UserID=t.UserID");
    sb.Append("INNER JOIN Topics AS p ON p.TopicID=t.TopicID");
    sb.Append("WHERE u.UserID=@UserID");
    sb.Append("ORDER BY t.Date");

Another question will ORDER by date work.. that field is of type TimeDate as much as I remember.

Answer 1

Try this:

StringBuilder sb = new StringBuilder();
sb.Append("SELECT u.Name,t.ThreadTitle,t.Date, t.Views,t.Replies,p.Theme,p.Topics,t.PageNumber");
sb.Append(" FROM Users AS u");
sb.Append(" INNER JOIN Threads AS t ON u.UserID=t.UserID");
sb.Append(" INNER JOIN Topics AS p ON p.TopicID=t.TopicID");
sb.Append(" WHERE u.UserID=@UserID");
sb.Append(" ORDER BY t.Date");

And Yes, orderby should work.
