I have the following tables along with their attributes(the
stared fields show the primary key:
Agent(AgentPhoneNo*, NameOfAgent)
Constituency(ConstituencyNo*,
ConstituencyName,District,RegionCode)
PollingStation(StationNo*,ConstituencyNo*,AgentPhoneNo,
StationName)
VoteResults(Party*, ResultsCategory*,Votes, AgentPhoneNo*)
Results category has two values (S,L) and the number of
parties is variable
My issue is this, below is my code that returns the total
votes received by each party with each constituency. This
query works fine.
<cfquery name="WinningPartyinConstituency"
datasource="#request.datasource#">
SELECT c.ConstituencyName, s.ConstituencyNo, v.Party,
Sum(v.Votes) AS TotalVotes
From (Constituency c
INNER JOIN PollingStation s ON c.ConstituencyNo =
s.ConstituencyNo)
INNER JOIN VoteResults v ON s.AgentPhoneNo = v.AgentPhoneNo
WHERE v.ResultCategory = 'L' AND s.ConstituencyNo IN (Select
ConstituencyNo From Constituency)
Group By c.ConstituencyName, s.ConstituencyNo, v.Party
Order By c.ConstituencyName
</cfquery>
Now I want to check and return the name and total votes of
the party with the maximum votes within each constituency. And but
I can't seem to figure out how to do that, especially because the
max() function takes only to
values.
I will appreciate any guidance on how to write a query that
returns the the party with the maximum votes in each constituency
and the votes it got. TIA
