Database - strange error

If I understand You, database is not for sorting. If You want to sort database table, do it in sql instruction used by DataReader. I don't know about FindLastDate in Framework. An example from VS help: public void ReadMyData(string myConnString) { string mySelectQuery = "SELECT OrderID, CustomerID FROM Orders ORDER BY 1"; OleDbConnection myConnection = new OleDbConnection(myConnString); OleDbCommand myCommand = new OleDbCommand(mySelectQuery,myConnection); myConnection.Open(); OleDbDataReader myReader = myCommand.ExecuteReader(); ... myReader.Close(); myConnection.Close(); } You may to sort table using cluster indexes (in Informix etc. - I don't know about Access)
