Aggregate Functions In Where Clause
Aug 29, 2005
I was wondering if anyone can help me: I have for example Pupils that are being entered into a table (called log). A query then counts the number of entries for each pupil I then want it ONLY to show the pupils that have been entered in 10 times on todays date (using DATE()).
I know this doesnt work but this is what I want to do:
SELECT log.pupilNo, log.Forename, log.Surname, Count(log.pupilNo) AS Demerits
FROM log, Tally
WHERE (log.Date)=Date() AND COUNT(log.pupilNo)>9
GROUP BY log.pupilNo, log.Forename, log.Surname, log.pupilNo;
Apparenty you cannot have an Aggregate function in a where clause.
Does anyone know a solution, any help would be appreciated
Cheers

Hi,
Is it possible to add a calcualted field to a query that already uses 'sum'?

Is there any way to lookup items using DLookup or other functions that will return an array of values not just the first value found. Example: I have three employees in a complaint query. I am using Dlookup to identify them on my employee form. When I get to the same employee/employee id on my employees form, I have a label that flashes red to flag me that this employee appears on that complaint query. The problem that I am having is that it only flashes for the first employee found in the query, and the label only flashes for that one person. I would like the label to flash for the other two employees because the function should see that they are in the query results as well. Help please?!!!

I know SQL well enough, but I cant seem to get my query to work. Basically, I am trying to display a series of posts, with the number of comments on the side.
I have two tables, Entries and Comments, which look like this:
Entries
---------
IDTitleContent (memo field)
1CatsSomething about cats here
2DogsSomething else about dogs here
3RodentsMy pet rat runs in a wheel
etc.
Comments
--------
IDPostIDComments
11My cat's name is mittens
21I taught my cat how to throw a curve ball
33Rats like squeak toys
42Nobody likes dogs
53Bunnies make good pets
61Cats are witches in disguise
Comments.PostID corresponds to Entries.ID on a many-to-one relationship.
I want to run a query that will join the number of comments (which is a Count of each row in the Comments table where Comments.PostID = Entries.ID) to the existing table, so that it will look like this:
Entries (with #ofcomments joined)
----------
IDTitleContent (memo field)#ofcomments
1CatsSomething about cats here3
2DogsSomething else about dogs here1
3RodentsMy pet rat runs in a wheel2
etc.
Usually, this would be a really simple SQL statement, but as I am using a Memo field, I am getting a "cannot use Memo field in aggregate function" error.
I'm not sure what to do, any help would be appreciated :)

I have the following query. I got an error when I ran it.
Code:
SELECT COUNT([encounter_number] WHERE status = 'Death')/ COUNT([encounter_number]) AS Death Ratio, tbl_test.facility_type AS Type,
FROM tbl_test
GROUP BY tbl_test.facility_type;
I think the problem is that first WHERE clause inside.

Alright, I've got all the pieces to this puzzle, I just can't fit them together properly. I have two tables, tblTickets and tblTicketNotes. They are in a one-to-many relationship, there can be multiple Notes attached to a single ticket. I am trying to set up a query that will pull the first (earliest by date) note for each individual Ticket. Here are the fields from each table that would be of concern here:
tbTickets
TicketID - Autonumber - Primary Key
Issue - Text - I will be using this later as a criteria to limit with, but not neccessary
tblTicketNotes
NoteID - Autonumber - Primary Key
TicketID - Long Integer - This is the foreign key of the relationship
DateStamp - Date/Time - This is the Note Date, I only want the first (earliest date) one
Content - Memo -This is the note information I want
So all I want is the Content of the first/earliest Note for each individual Ticket. I know this should be fairly easy, but I am at a loss.

I have a problem with a nested arrangement of Right, DLookup and DMax functions.
The function is for a default value in a text control
=Right(DLookUp("[SampleNumber]","tbldat14A_MasterSampleList","[SampleID]=" & DMax("[SampleID]","tbldat14A_MasterSampleList"))+1000001,6)
I am trying to retrieve the last record from a field SampleNumber which is alphanumeric (e.g. "AK005434") and then add a 1 to it as the next SampleNumber. I had previously used a default value in the txtSampleNumber control as
="AK" & Right(1000000+DMax("[Clip]","[tbldat14A_MasterSampleList]")+1,6)
where [Clip] was a field I have calculated in the table to chop off the preceding characters. Adding 1,000,000 and taking the 6 right hand values and concatenating with "AK" gave me the answer, though it is a but primitive.
This all worked until the SampleNumber value got out of order and blocks of SampleNumber values came in that were then followed by blocks of numbers with lower values (say AK005001-AK005050 followed by AK002001-AK002050).
Now I figure if I just recall the latest entry by DLookup and criteria of DMax on the SampleID (Autonumber Primary key) I could get at the value. I have done this to some success using default values in a series of unbound controls like
=DLookUp("[SampleNumber]","tbldat14A_MasterSampleList","[SampleID]=" & DMax("[SampleID]","tbldat14A_MasterSampleList"))
to get the SampleNumber I require, then a Right function to trim in another unbound box and then use that last unbound box as the default value for the txtSampleNumber control that is the entry for the data table. However, the unbound control box is only valid for the first record and does not update. So, I added a macro that closes the form and reopens it. This all works but is a bit agricultural. I would like to do a single nested function to the default value of the txtSampleNumber control box. Is it possible to nest Right, DLoopkup and DMax into one statement?

I'm having a problem with queries, and I can't seem to find a solution in books - I looked through about ten of them and none of them addressed the problem. This may be because it has a painfully obvious solution...
A little background:
I am designing a database for a debt-collection law firm. One of the functions it must have is to keep track of various different sorts of financial transactions which can pertain to a given debtor (ie, a received payment, a cost expended, and a few other things).
The problem is that, in generating reports, I need to use queries to find several sums of only those transactions which fall into specific categories (for instance, to calculate the amount a debtor has paid against his balance, it needs to sum only those entries which are both linked to that debtor's ID number and whose type field reads "payment", and then subtract from that those entries whose type field reads "cost"). The problem is this: not all debtors may have "costs" entries, and when there are none, the report comes up blank with a single "#Error" written in the name field and nothing else present.
I believe the problem is that the Sum aggregate is returning a null value when the query finds nothing that meets the criteria. I have been unable to find a way around this; the Nz() and IIf() with IsNull() functions don't seem to be helping.
The query runs as intended when there are entries for every relevant type; however, it is undesired to have to enter a "payment" of $0, "cost" of $0 etc for every entry just so that this function works.
Is there anything I can do about this? Any input would be appreciated, as I'm fairly inexperienced with the use of Office Access. (If it matters, I am using Office 2003).

I have a SQL query to gather data from a number of tables (balances, accounts, currencies)
Quote:
SELECT [tblBalances].[BalanceDate], [tblAccounts].[AccountNumber], [tblCurrencies].[Ccy], [tblBalances].[Amount], ([tblBalances].[Amount]*[tblRates].[FXRate]) AS AmountUSD
FROM (([tblBalances] INNER JOIN [tblAccounts] ON [tblBalances].[AccountID]=[tblAccounts].[AccountID]) INNER JOIN [tblCurrencies] ON [tblBalances].[CcyID]=[tblCurrencies].[CcyID]) INNER JOIN [tblRates] ON ([tblBalances].[BalanceDate]=[tblRates].[RateDate]) AND ([tblBalances].[CcyID]=[tblRates].[CcyID])
WHERE BalanceDate = #12/10/2013#
How do I add 'AmountUSD' to the WHERE clause (such that I can only return records above or below a certain value, for example)
Along the lines of :
Quote:
WHERE BalanceDate = #12/10/2013# AND AmountUSD>1000
I know it's an issue with referring to aggregated functions in the WHERE clause and you're supposed to use HAVING instead

Hello,
I have a table as such:
NAME RANK WIN_PERCENT DRAW_PERCENT
The table can have the same people in it multipe times, such as:
NAME LEVEL WIN_PERCENT DRAW_PERCENT
Bob 4 80% 4%
Bob 5 90% 5%
Bob 8 60% 3%
What I would like to do is return only the row in which Bob's Level is the Highest (MAX).
I wrote an aggregate query as such:
SELECT NAME, MAX(LEVEL) AS MAX_LEVEL, WIN_PERCENT, DRAW_PERCENT
FROM MYTable
GROUP BY NAME, WIN_PERCENT, DRAW_PERCENT
The problem is, as you'd expect, this query returns all rows, since I am grouping by WIN_PERCENT and DRAW_PERCENT as well.
Any ideas on what query to use to just return the row with the highest (MAX) LEVEL? i.e.
NAME LEVEL WIN_PERCENT DRAW_PERCENT
Bob 8 60% 3%
Thanks,
Scott

Hey guys, can anybody help

Name
JobTask as you can see the relationship between Job and Task is M-M
JobId-----PK

Task
TaskId-----PK
TaskName
TaskCompetency as you can see the relationship between Task and Competency is M-M
TaskId-----PK
CompetencyId-----PK
Competency
CompetencyId-----PK
CompetencyName
Keyword
Priority
I have a query like this:
The user will input the JobId, PositionId, ActivityId.
I want to return all the TaskName ,CompetencyId, CompetencyName
Where the following:
The highest priority within the same keyword
Basically group by keyword then pick the highest priority I have done this:
SELECT Max(Competency.Priority), Competency. Keyword
FROM Competency INNER JOIN ((ActivityTask RIGHT JOIN (positionTask RIGHT JOIN (JobTask RIGHT JOIN task ON JobTask.TaskID = task.TaskID) ON positionTask.TaskID = task.TaskID) ON ActivityTask.TaskID = task.TaskID) INNER JOIN TaskCompetency ON task.TaskID = TaskCompetency.TaskID) ON Competency.CompetencyID = TaskCompetency.CompetencyID
WHERE (((JobTask.JobID)=[job])) OR (((positionTask.PositionID)=[position])) OR (((ActivityTask.GroupID)=[Activity]))
GROUP BY Competency.CompetencyKeyword;
It works fine, it returns the all the keyword, and its highest priority.
But I can’t return the Competency.CompetencyId, Competency. CompetencyName with the aggregate function Max

Hello! .... I think I posted this in the wrong section of the forum, so here it is again and hope someone's kind enough to help. Basically, I've been asked to show (in a form as well as a report) results on a Monthly, Quarterly and Year-to-Date basis. The table structure I currently have is as follows (additional fields and/or tables can be added if it would help get the results desired):
ID Date Volume/Value
A1 Jun-05 10,000
A2 May-05 15,000
A3 Apr-05 12,000
A4 ------ ------
An May-04 11,000
B1 Jun-05 10,000
B2 May-05 15,000
B3 Apr-05 12,000
B4 ------ ------
Bn May-04 11,000
Part of the trick with this is to be able to show these aggregate values (quarterly, YTD, and on a 13-month rolling basis) as users enter new data for whatever the current month is. Any assistance in helping me get this accomplished would be enourmeously appreciated.

Hi All,
I have a table namely, leave_details wherein there is a column called DAYS and TDAYS,
DAYS columns represent number of leaves an employee has taken in a single leave application and
TDAYS represents Total number of leaves an employee has availled till date.
To calculate the TDAYS i need to SUM the DAYS column for every employee.
When an employee again log in the application he should be aware of the total number of leaves which he has already availed.
Please help me for the same as I am unable to do so.
Kindly revert back for any queries or any further information.
With Warm Regards,

Hi,
I am working on a marketing database. I have two tables that are in use called tblListInfo and tblResults.
In tblListInfo the fields I am using are DropDate, ListName and Marketcode.
In tblResults the fields I am using are JoinDate and Marketcode.
I am attempting to write a query that the end result will display the number of records within the 1st week of the promotions drop date. For every combination where the ListName value AND the DropDate value are unique, I want to count the number of records in tblResults that have JoinDate BETWEEN DropDate AND DropDate + 6.
I tried writing the code for this in pieces starting with:
SELECT DISTINCT tblListInfo.[ListName], tblListInfo.[DropDate]
FROM tblResults
INNER JOIN tblListInfo
ON tblResults.[Marketcode] = tblListInfo.[Marketcode]
This gave me my first ideal part of the output I was seeking. I listing of all the possible marketing lists used with duplicate names occuring only when there were different drop dates. for example:
Listname Drop Date
List - 1 1/1/08
List - 1 1/15/08
List - 2 1/1/08
List - 2 2/5/08
From there I wanted to modify the process to include a third field that included the # of records in tblResults that have the JoinDate field BETWEEN tblListInfo.[Drop Date] AND (tblListInfo.[Drop Date]+6). The ideal output would be like this:
Listname Drop Date Week 1
List - 1 1/1/08 15
List - 1 1/15/08 8
List - 2 1/1/08 32
List - 2 2/5/08 12
My attempt at getting to this result is below:
SELECT DISTINCT tblListInfo.[drop date], tblListInfo.[ListName], count(tblResults.[join date]) AS [Week 1]
FROM tblResults
INNER JOIN tblListInfo
ON tblResults.[MarketCode] = tblListInfo.[MarketCode]
WHERE tblResults.[Join Date] BETWEEN tblListInfo.[drop date] AND (tblListInfo.[drop date]+6)
I receive an error at this point saying: "You tried to execute a query that does not include the specified expression 'ListName' as part of an aggregate function."
Can anyone offer suggestions/corrections to my approach and logic?

I have a subform (in continuous record view) which displays products on an order items form. Each record has a DMin control to find the lowest price for its product (each product can have many suppliers and therefore many prices). I need to put a control in the subform footer containing the sum of the minimum prices.
Access doesn't seem to want to sum calculated controls, so could someone please point me in the direction of how to go about doing this or achieving the same result through a different method?

Hi all,
I need some help in sorting out this query.
My Table looks like this..
Manifest Weight StopNo State
------- ------- ------- ------
71545 1000 10 VA
71545 1000 20 TN
71545 500 30 AL
Some Manifests are repeating
There are multiple stops within each manifest (eg.: 10, 20, 30) and each stops has itsown weight info and State.
What I am trying to figure out is the number of manifests, total weight within manifest, and the last stop and state of the manifest
Query:
SELECT ManifestNo, Count(ManifestNo), Sum(Weight), Last(Stop No), Last(State)
FROM RBP
WHERE ShipmentType="ROAD"
GROUP BY ManifestNo;
My Problem: Everything works fine, but the state of the last stop is not displaying properly..
My result is - 71545 3 2500 30 TN
Correct output should be - 71545 3 2500 30 AL
I tried to remove the "last" from State but its gives me the aggregate function error. Any suggession ?
Thanks in advance..

Morning!
I have quite a few aggregate functions within a report I produced based on 2 queries. I need to do a mail merge with this information, but it is not all in one single query, because I cannot get an expression using totals in a field. How do you get these aggregate functions to be a part of the query, so it can eventually be part of the mail merge? It is unfortunate that you can't just use a report to mail merge, because all my equations are in the report.
