I have a fantasy football league that I am keeping stats for in an Access Database. I need help coming up with a way to calclulate the winning % for each team for their entire career. What I have is a table with the following fields:
Fantasy Team
Season
Week
W/L
Own Score
Vs
Opponent
Opponent Score
Game type
The W/L field will either have a W or a L depending if they won or loss, the Vs field will either have a vs or a @ depending if its a home or away game, and the Game Type field tells if it was a regular season game, playoff game, Super bowl game, or Toilet bowl game.
What I have done so far is I created a query on the above table to sort out just the winners and this new table is called Winners. I then created a crosstab query called Winners_Crossta b that counts the number of Wins each team has had for each season. So now I have totals wins. I then did the same thing for losses to end up with a query called Loosers_Crossta b. The last thing I did was to create another query called WinPercentage and added the Winners_Crossta b and Loosers_Crossta b and linked the two tables by Fantasy team. The fields include:
Fantasy Team
Count of Wins
Count of Losses
Win%
The win% field is one I added manually and is a calculation of
wins/(wins+losses)*1 00
This works fine except for when a team has no wins or no losses. If a team went 14-0 then the team doesn't show up in the WinPercentage query. I understand why it doesn't but I don't know how to get around this. I hope I made this clear enough for you to give me some quidance. I am new to databases and just started learning Access about 4 months ago.
Thanks for your help,
Scott

I think that is the same code you gave me before. When I go to design mode and set win% to sort descending, I get the parameter windows that pop up and then when it runs it doesn't sort.

I assume if you use order by [win%] it doesn't work.
I'm afraid it just might not be possible to set the order by in the query. Where are you going to use the query?

OK, one last try ... -
SELECT [SB Games].[Fantasy Team],
-
Sum(IIf([SB Games].[W/L]="W",1,0)) AS [Total Of W],
-
Sum(IIf([SB Games].[W/L]="L",1,0)) AS [Total Of L],
-
[Total Of W] / NZ([Total Of W]+[Total Of L],1)*100 As [win%]
-
FROM [SB Games]
-
GROUP BY [SB Games].[Fantasy Team]
-
ORDER BY Sum(IIf([SB Games].[W/L]="W",1,0)) / NZ(( Sum(IIf([SB Games].[W/L]="W",1,0))+ Sum(IIf([SB Games].[W/L]="L",1,0))),1)*100

YOU DID IT!!! THANK YOU THANK YOU THANK YOU THANK YOU.
Its working now. I have the information going to EXCEL and then I copy the information into a web page. My next project will be to figure out how to generate a web page directly from the information from the DB. I tried creating an .ASP page but it takes about 2 minutes to load all the data and thats way too long. One problem solved though.
Thank you so much.

You're welcome Scott. Glad its working.
Mary,
Is there a way to replace the NZ with an IIF function because when I try to pull the data from within Excel I get a "Undefined Function 'NZ' in Expression."

Change -
NZ([Total Of W]+[Total Of L],1)*100
to -
IIf([Total Of W]+[Total Of L]=0,1,[Total Of W]+[Total Of L])*100
and change -
NZ((Sum(IIf([SB Games].[W/L]="W",1,0))+ Sum(IIf([SB Games].[W/L]="L",1,0))),1)*100
to -
IIf(Sum(IIf([SB Games].[W/L]="W",1,0))+Sum(IIf([SB Games].[W/L]="L",1,0))=0,1,Sum(IIf([SB Games].[W/L]="W",1,0))+Sum(IIf([SB Games].[W/L]="L",1,0)))*100
OK that worked.
There was no way I could have done this by myself.
Thanks again

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
