HOw Do I count and identify the number of groups in a groups output.

Question

I have a query that reads like this..
SELECT s.spec_Sort,s.spec_ID, s.spec_Name, b.bus_Name,
b.bus_ID
FROM (tbl_businesses as b INNER JOIN tbl_SpecBusRel as sb ON
b.bus_ID = sb.specbus_busid) INNER JOIN tbl_specialties as s ON
sb.specbus_specid = s.spec_ID
ORDER BY s.spec_Sort, b.bus_Name
and then I am outputing like this...
<cfoutput query="rsGetSpecialties" group="spec_Name">
<cfif THIS IS WHAT I
NEED)></td><td></cfif>
<h2><a class="specialty" href="javascript;"
onclick="dwfaq_ToggleOMaticDisplay(this,'#spec_ID#');return
document.MM_returnValue">#spec_Name#</a></h2>
<div id="#spec_ID#" style="display:none">
<cfoutput><p><a
href="#request.details#?bus_ID=#bus_ID#">#bus_Name#</a></p></cfoutput>
</div>
</cfoutput>
This displays in this manner...
Specialty
dealer
Specialty
dealer1
dealer2
Etc...
What I am trying to do is find out how many specialties there
are, figure out where the middle is so I can insert a new table
data cell and start a new column.
Basically - two columns with the data divided in half by
specialty NOT by the number of dealers.
I hope that makes sense. Of course I am trying to do it w/ as
little query action as possible. My only solution may be to have
more than one query and the second only finds a list of the
sepcialties that contain the dealers and then find the middle one
and simply say if current specialty = middleSpecialty then start a
new column.
Thanks all,
Chris

Answer 1

Thanks for the replies. I don't need the number of occurances
of each specialties - I simply need to know how many specialties
there are and then split them in half.
This may be the long way around -but it is what I did...
<cfquery name="rsGetSpecialties" >
SELECT s.spec_Sort,s.spec_ID, s.spec_Name, b.bus_Name,
b.bus_ID, b.bus_Pcity, b.bus_PState
FROM (tbl_businesses as b INNER JOIN tbl_SpecBusRel as sb ON
b.bus_ID = sb.specbus_busid) INNER JOIN tbl_specialties as s ON
sb.specbus_specid = s.spec_ID
ORDER BY s.spec_Sort, b.bus_Name
</cfquery>
<cfset specs = valuelist(rsGetSpecialties.spec_ID)>
<cfquery name="rsListSpecialties">
SELECT spec_ID,spec_Name
FROM tbl_specialties
WHERE spec_ID in(#specs#)
ORDER BY spec_Name
</cfquery>
<cfset middle = int(rsListSpecialties.recordcount/2)>
<cfset specs = valuelist(rsListSpecialties.spec_Name)>
<cfset middle = listgetat(#specs#,middle)>
then displayed like this...
<td valign="top" width="50%">
<cfoutput query="rsGetSpecialties" group="spec_Name">
<h2><a class="specialty" href="javascript;"
onclick="dwfaq_ToggleOMaticDisplay(this,'#spec_ID#');return
document.MM_returnValue">#spec_Name#</a></h2>
<div id="#spec_ID#" style="display:none">
<cfoutput><a
href="#request.details#?bus_ID=#bus_ID#">#bus_Name#
(#bus_PCity#, #bus_PState#)</a><br /></cfoutput>
</div>
*****This is the line that does the splitting *****
<cfif spec_Name EQ middle></td><td
valign="top" width="50%"></cfif>
</cfoutput>
</td>
As for removing the extraneous cfoutput --> I thought that
I needed that in order to show the material within the grouped
data. HOw does CF know what data to repeat and what data to not
repeat in a grouped output? I will have to look this one up some
more.
thanks for the help
