Question

I have a C# SQL query for my asp.net page which queries the database using a value stored in the session of my page (called tournyName). I have the query working, and I am using a SqlDataReader (called myReader) to read the results of the query. I cant however get the results to display on the HTML area of my page.
I have been piecing together bits of code that I have found from other peoples questions and the code at this point is incomplete. It looks something like this:

C# (snppit):

    conn.Open();
    query = "SELECT GamePlayer1 AS [Player 1], GamePlayer2 AS [Player 2], GamePlayer1Score AS [Score1], GamePlayer2Score AS [Score2] FROM Games WHERE (TournyName = '@TournyName')";

    com = new SqlCommand(query, conn);

    com.Parameters.Add(new SqlParameter("@TournyName", SqlDbType.VarChar, 200));
    com.Parameters["@TournyName"].Value = Server.HtmlDecode(tournyName.Trim());

    SqlDataReader myReader;
    myReader = com.ExecuteReader();
    myRepeater.DataSource = myReader;
    myRepeater.DataBind();

And my HTML, where I would like to display the results:

<asp:Repeater id="myRepeater" runat="server">
<HeaderTemplate><table border="1"></HeaderTemplate>
<ItemTemplate>
<tr><td>
</td>
<td>
<%# Eval('Player 1')%>
</td>
<td>
 <%# Eval('Player 2')%>  
<td>
 <%# Eval('Score1')%>  
</td>
<td>
 <%# Eval('Score2')%>  
</td>
</tr>
</ItemTemplate>
<FooterTemplate></table></FooterTemplate>
</asp:Repeater>

No matter what I try, the page just shows up as blank. Can anybody enlighten me as to how I would display this?

There are a couple of things:

• Since you are using a parameter (good!), you mustn’t escape the parameter token in the SQL Query with quotes, i.e. just

SELECT GamePlayer1 AS [Player 1], GamePlayer2 AS [Player 2], GamePlayer1Score AS [Score1],
GamePlayer2Score AS [Score2] FROM Games WHERE (TournyName = @TournyName)

• Eval needs double quotes, i.e. <%# Eval("Player 1")%>

Also, remember to Dispose your connection, command and SQLReader.
