Cross reference categories will performing a count

Hello all,

I have two tables.  One is a list of Categories, the other is a list of items with those categories assigned to each item.  There is a one to many relationship between the two tables.

tblCategories
---------------------
catName
catID

tblItems
---------------
ItemID
ItemName
catID

I need to count the number of items in tblItems for each category that is contained in tblCategories.  Moreover, I need to retrieve this data so that I can display it on a webpage, so I need to return, the catID and the Count of items with that catID.  I want to use a stored procedure.

---Desired Output------
catID     Count
1              22
2              109
3              67
etc. . .
--------------------------


Can someone please help me?

CREATE PROCEDURE sp_CatItemCount AS

SELECT CatName, COUNT(ItemID) AS CountOfItem
FROM tblCategories C
INNER JOIN tblItems I ON C.CatID = I.CatID
GROUP BY CatName

oopss...  You wanted CatID not CatName

CREATE PROCEDURE sp_CatItemCount AS

SELECT C.CatID, COUNT(ItemID) AS CountOfItem
FROM tblCategories C
INNER JOIN tblItems I ON C.CatID = I.CatID
GROUP BY CatName

Then on your web page you could do this...

<%

Dim oCn
Dim rs
Dim sql

sql = "sp_CatItemCount"

Set oCn = Server.CreateObject("ADODB.Connection")
oCn.Open "DSN=DSNName; uid=username; pwd=password"

Set rs = Server.CreateObject("ADODB.Recordset")
rs.Open sql, oCn, 1, 1, adCmdStoredProc

%>

<table>
<tr>
<td><%= rs(0).Name %></td><td><%= rs(1).Name %></td>
</tr>

<%
Do until rs.eof
%>

<tr>

<%
For x = 0 to rs.Fields.Count - 1
%>

<td><%= rs(x) %></td>

<%
Next
%>

</tr>

<%
rs.MoveNext
Loop
%>

</table>

rs.Close
Set rs = Nothing

oops, my bad on the above SQL Statement...
Forgot to group by C.CatID not CatName

SELECT C.CatID, COUNT(ItemID) AS CountOfItem
FROM tblCategories C
INNER JOIN tblItems I ON C.CatID = I.CatID
GROUP BY C.CatID
