Re: [MS_AccessPros] Query not responding

 

Hi Duane
 
Hopefully a couple of simple tweaks (!)
 
1. In the crosstab query, when a value comes out as zero, it displays as blank - how can I get them to display as 0.00?
 
2. When the crosstab query is being displayed, I can select totals(the sigma icon)and the use the totals bar. However, unlike in other queries where if I save the query and that causes the totals bar to appear next time I open that query, on the crosstab query the totals line doesn't re-appear and I have to select totals again. Can this be changed so that once selected (and saved) it comes up every time?
 
Indeed, where is the setting for this totals bar stored to make it appear each time in standard queries?
 
cheers
 
Phil

Phil,

In order to understand the crosstab, it is best to change it to a standard totals query to view the data. The crosstab only transforms/pivots the data by moving one group by column to the column headings.

There are a couple other "tricks" in the query I provided so feel free to ask.

Regards,
Duane

Hi Duane
 
Excellent - that seems to be doing the required job. I need now to go through it all in detail to make sure I fully understand how it all fits together. If I am unclear about anything I hope it is ok if I get back to you for further explanation.
John - if you want to abandon the other avenue now that will be fine as I don't want to waste your time although it would be nice to know why it isn't giving the correct figures and maybe to get it to the stage where it does.
 
Many thanks to you both for your time and expertise in helping me with my problem.
 
Phil

First create a query to get your totg
===== qgrpRefSeaTotg =====
SELECT [Matches for grid - league].refid AS gRefID, [Matches for grid - league].seasonid AS gSeasonID, Count([Matches for grid - league].id) AS Totg
FROM [Matches for grid - league]
WHERE (((Month([date]))<>5))
GROUP BY [Matches for grid - league].refid, [Matches for grid - league].seasonid;

Then add this query to your crosstab;

PARAMETERS [forms]![live games]![referee] Short;
TRANSFORM Count([id])/First([TotG]) AS Expr1
SELECT [Matches for grid - league].seasonid, 
Sum(Abs([sendingsoff]>0 And [RangeName]="all")) AS Reds, 
qgrpRefSeaTotg.Totg
FROM Ranges, qgrpRefSeaTotg INNER JOIN [Matches for grid - league] ON (qgrpRefSeaTotg.gSeasonID = [Matches for grid - league].seasonid) AND (qgrpRefSeaTotg.gRefID = [Matches for grid - league].refid)
WHERE ((([Matches for grid - league].refid)=[forms]![live games]![referee]) AND
(([Matches for grid - league].totbooks) Between [fromnum] And [toNum]) AND ((Month([date]))<>5))
GROUP BY [Matches for grid - league].seasonid, qgrpRefSeaTotg.Totg
PIVOT Ranges.RangeName;

Hi Duane
 
OK I have set this up but there is still much I don't yet fully understand and if you can help me through it I would appreciate it
 
I have simplified it a bit in that I have included the criteria for the referee and also to exclude the month of May into the original query as these 2 filters apply throughout.
 
I need the most of the values that are returned in the grid to be divided by [totg] where [totg] is the total number of games for the season we are currently processing. I have been using Count of id to arrive at this value. Totg needs to be added as a column itself as well as being used as the divisor for the other values
 
It must be something similar to the way you added a column for reds and maybe if you can show me how to do it it will enable me to move forwards
 
many thanks
 
Phil

If you have a chance to try something new (learn something new).... I just created the table Ranges
Ranges
RangeNameFromNumToNum
000
0-10010
0-20020
0-30030
0-40040
0-50050
0-60060
0-70070
30-403040
40-604060
all010000

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;

This assumes RefID is numeric.

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.

Duane

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;

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.

WHERE (((Month([date]))<>5) AND (([Matches for grid - league].Refid)=[forms]![Live Games]![referee]))

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
