If you have a chance to try something new (learn something new).... I just created the table Ranges
| RangeName | FromNum | ToNum |
|---|---|---|
| 0 | 0 | 0 |
| 0-10 | 0 | 10 |
| 0-20 | 0 | 20 |
| 0-30 | 0 | 30 |
| 0-40 | 0 | 40 |
| 0-50 | 0 | 50 |
| 0-60 | 0 | 60 |
| 0-70 | 0 | 70 |
| 30-40 | 30 | 40 |
| 40-60 | 40 | 60 |
| all | 0 | 10000 |
Then created a crosstab query with SQL of:
PARAMETERS [forms]![live games]![referee] Short;
TRANSFORM Count([Matches for grid - league].id) AS CountOfid
SELECT seasonid, Sum(Abs([sendingsoff]>0 And [RangeName]="all")) AS Reds
FROM [Matches for grid - league], Ranges
WHERE refid=[forms]![live games]![referee] AND totbooks Between [fromnum] And [toNum] AND Month([date])<>5
GROUP BY seasonid
PIVOT Ranges.RangeName;
The query is very efficient and allows you to do some calculations in your form or report. If you want to do it in a query, you may need to create a simple totals query that counts all by referee and season. Then combine the two queries and do the math.

still returning whole numbers.
I am fairly sure the figures I am getting are the counts themselves but they are not being divided by gtot for some reason?

Phil-
Try wrapping a CDbl around either part of the expression, as in:
SUM(qryZero.Count0) / CDbl(totg) As 0

Hi John
something not quite right in the calculations where I am dividing by totg - they are all coming out as integers whereas they should all come out with values between 0 and 1
typically totg represents the total games in a season for the specified ref and count0 is always a subset of those same games
any ideas?

Phil-
I would pull out each of the DCounts into separate queries. For example, convert:
DCount("id","matches for grid - league","[totbooks]=0 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg]
into:
qryZero:
SELECT MGL.Season, COUNT(id) As Count0
FROM [matches for grid - league] AS MGL
WHERE [totbooks]=0 AND [refid]= [forms]![live games]![referee] and month([date])<>5
GROUP BY Season;
Then incorporate it back into your main query using an INNER JOIN:
SELECT [Matches for grid - league].Season, Count([Matches for grid - league].id) AS totg, Avg([Matches for grid - league].totbooks) AS avbk, SUM(qryZero.Count0) / totg As 0
FROM [Matches for grid - league] INNER JOIN qryZero ON [Matches for grid - league].Season = qryZero.Season
WHERE (((Month([date]))<>5) AND (([Matches for grid - league].Refid)=[forms]![Live Games]![referee]))
GROUP BY [Matches for grid - league].Season
ORDER BY [Matches for grid - league].Season DESC;
FROM [Matches for grid - league] INNER JOIN qryZero ON [Matches for grid - league].Season = qryZero.Season
WHERE (((Month([date]))<>5) AND (([Matches for grid - league].Refid)=[forms]![Live Games]![referee]))
GROUP BY [Matches for grid - league].Season
ORDER BY [Matches for grid - league].Season DESC;
I threw the SUM in there to make sure you don't get a bogus error because Count0 isn't in the GROUP BY - it should be a SUM of exactly one row! "Simply" do that for each of your DCOUNTs - building up a complex INNER JOIN.

before my last change I had it working on the table 'matches' but I need it to analyse a particular type of match (ie league matches) so I changed it to run on a query which selects just the league matches.
there are about 60000 matches and maybe 45000 league matches.
cheers

If a query is "too big", you should get a "query too complex" error. If it's taking a long time to run, perhaps it could be optimized. What's the SQL of the query?

Hi John
That looks as if it might be where the issue lies - I will look into it and let you know
many thanks for that.
Another one for you whilst I have you if you don't mind.
I have a query which causes the message 'Access is not responding' - it is quite a complex query in that it has about 12 fields which use fairly involved dcounts.
Is it possible that a query simply becomes too 'big' to run?
cheers
Phil
