Hi All,

I have a database reader class. But i want to use this class, sometimes SqlDataAdaptor.Fill() method get another query to Datatable.

I look at Query in SqlCommand Instance and my query is correct but returning values from different table?

What is the problem?

This My Code

public static DataTable GetLatestRecords(string TableName, string FilterFieldName, int RecordCount, params DBFieldAndValue[] FilterFields) { DataTable DT = new DataTable(); Type ClassType = typeof(T);

        string SelectString = string.Format("SELECT TOP ({0}) * FROM {1}", RecordCount, TableName);

        if (FilterFields.Length > 0)
        {
            SelectString += " WHERE 1 = 1 ";

            for (int index = 0; index < FilterFields.Length; index++)
                SelectString += FilterFields[index].ToString(index);
        }

        SelectString += string.Format(" ORDER BY {0} DESC", FilterFieldName);

        try
        {
            SqlConnection Connection = GetConnection<T>();
            SqlCommand Command = new SqlCommand(SelectString, Connection);

            for (int index = 0; index < FilterFields.Length; index++)
                Command.Parameters.AddWithValue("@" + FilterFields[index].Field + "_" + index, FilterFields[index].Value);

            if (Connection.State == ConnectionState.Closed) Connection.Open();
            Command.CommandText = SelectString;
            SqlDataAdapter DA = new SqlDataAdapter(Command);
            DT.Dispose();
            DT = new DataTable();
            DA.Fill(DT);

            if (Connection.State == ConnectionState.Open)
                Connection.Close();
        }
        catch (Exception ex)
        {
            WriteLogStatic(ex.Message);
            throw new Exception(@"Veritabani islemleri sirasinda hata olustu!\nAyrintilar 'C:\Temp' dizini altindadir.\n" + ex.Message);
        }
        return DT;
    }
