Strange difference between SQL from .Net and SQL within stored proc

Hi, I am trying to fill a DataGrid with random records from my database. It thought I had found a way to randomly select records using SQL. So I built a stored procedure in Access and sure enough, it returns a random set of records.

Whe I tried to call this from my app, it kept returning the same set of records. So I copied and pasted the SQL into the app (code below) but it made no difference. Could anyone tell me why this wouldn't work?

<%@ Page Language="VB" ContentType="text/html" ResponseEncoding="iso-8859-1" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.OleDB" %>

<script runat="server">
Public objConn as new OleDbConnection (System.Configuration.ConfigurationSettings.AppSettings("ConnectionString"))

Sub GetTeam(s as Object, E as EventArgs)
 Dim objCmd As New OleDbCommand("SELECT TOP 4 PlayerID FROM tblPlayers WHERE PositionID='defender' ORDER BY rnd(isnull(PlayerID)*0+1);", objConn)
   dgDef.DataSource = objCmd.ExecuteReader
 Catch ex as OleDbException
   throw ex
 End try

End Sub

Have you tried: "SELECT TOP 4 PlayerID FROM tblPlayers WHERE PositionID='defender' ORDER BY newid()".

This seems to work pretty good and I have found sites on the web that discuss using newid() versus rnd()Idea [Idea] (Such as MSDN).

Yeah, I had seen the NewID option in my web searches on the problem - tried it but came up with the following error:

Undefined function 'newid' in expression.

Any ideas where to go from there?

Are you using an Access Project? If so, what was your query this time?  What version of SQL Server are you using? OS?

4/19/2006 1:13:51 PM

Sorry, that is the whole query.


I'm just using Access as my DB for my ASP.Net website. I build what Access calls 'Queries' and use them like Stored Procedures from my .Net pages.

Access 2000

Well,  Access as a data store is a whole new ballgame and not my cup of tea.  I use it only as a thin client.  I'm sorry. I was confused by 'Stored Procedures'.  That makes newId() useless.

Try looking here  This seems a bit ridiculous, but so is everything else in Access (For someone familiar with SQL2000)

My guess is that you are not setting the seed value for the random function.  This would casue the same order every time you run the query (computers compute a random number.  Therefore, if the seed is the same, you will get the same 'random' output every time!)  Try seeing if you can set the seed value.

Hope this helps.

Dynamic sql within a stored proc
i am using Adaptive Server Anaywhere 6.03. i am trying to find a way to create a cursor within a Stored Proc based on a 'Where' clause passed to the SP as a parameter. The reason that i need a 'where' clause is that; if i pass parameters for dealling with seperate fields, i have to create many cursors depending on which fields i wish to filter and fields that i don't wish to filter. furthermore, i have to repeat the main part of my SP in order to deal with each and every cursor. while this is workable, it leads to SPs that are ridiculously long and difficult to main...
