Re: [MS_AccessPros] Query not responding

 

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.

Here goes - good luck!

 

SELECT [Matches for grid - league].Season, Count([Matches for grid - league].id) AS totg, Avg([Matches for grid - league].totbooks) AS avbk, DCount("id","matches for grid - league","[totbooks]=0 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS 0, DCount("id","matches for grid - league","[totbooks]<11 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-10], DCount("id","matches for grid - league","[totbooks]<21 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-20], DCount("id","matches for grid - league","[totbooks]<31 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-30], DCount("id","matches for grid - league","[totbooks]<41 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-40], DCount("id","matches for grid - league","[totbooks]<51 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-50], DCount("id","matches for grid - league","[totbooks]<61 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-60], DCount("id","matches for grid - league","[totbooks]<66 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-65], DCount("id","matches for grid - league","[totbooks]<71 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [0-70], DCount("id","matches for grid - league","[totbooks] between 30 and 40 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [30-40], DCount("id","matches for grid - league","[totbooks] between 40 and 60 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [40-60], DCount("id","matches for grid - league","[sendingsoff]>0 and [refid]= [forms]![live games]![referee] and [season] = '" & [season] & "' and month([date])<>5 ")/[totg] AS [reds%]
FROM [Matches for grid - league]
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;

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

Phil-

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
