efficient asp.net sql query - asp.net

Question

Been using this site for years and have always found it very helpful and normally all my questions get answered by reading the site.
I have some case studies on a site than need to be related to other sections of the site and i am using this code to pull the records from the database :-
<div id="sidebar">
<asp:accessdatasource
id="cskey"
runat="server"
datasourcemode="DataSet"
datafile="_db/db.mdb"
selectcommand="SELECT id FROM markets_case_assign WHERE productid = #catid">
<SelectParameters>
<asp:QueryStringParameter Name="catid" QueryStringField="id" DefaultValue="1" />
</SelectParameters>
</asp:accessdatasource>
<asp:Repeater id="cskeycontent" runat="server" DataSourceID="cskey">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Visible="false" Text='<%#Eval("id")%>'></asp:Label>
<asp:accessdatasource
id="csval"
runat="server"
datasourcemode="DataSet"
datafile="_db/db.mdb"
selectcommand="SELECT id,title,company FROM casestudies WHERE id = #pid">
<SelectParameters>
<asp:controlparameter name="pid" controlid="Label1" DefaultValue="1" />
</SelectParameters>
</asp:accessdatasource>
<asp:Repeater id="csvalcontent" runat="server" DataSourceID="csval">
<ItemTemplate>
<div class="case-studies">
<h2><%#Eval("company")%></h2>
<p><%#Eval("title")%></p>
<p class="no-margin-bottom">Read case study</p>
</div>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
</asp:Repeater>
</div>
I was just wondering if there is a simpler way of doing it.
Any help would be much appreciated.
Cheers Andy

Answer 1

i was wondering if there was a way of doing it with only one query
To make it one query, just change the SQL call as:
SELECT id,title,company FROM casestudies
WHERE id IN (SELECT id FROM markets_case_assign WHERE productid = #catid)
and use only one repeater (the inner one).
Now you lose the extra advanced to separate them with some extra header, line etc..
