i need domain aggregate functions to count the occurrences of specific value in a field, and when it exceeds 1, display null. or 'group by' subqueries with count() to see if you should populate the field or not.
View RepliesIs 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?!!!
View 2 Replies View RelatedAlright, 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 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 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?
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

Hi,
Is it possible to add a calcualted field to a query that already uses 'sum'?
I want to take the value returned by sum and add the value of another field to it.
Any help will be very much 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.
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 need to build an expression: calculate the total number of years worked given the start date and end date.

I'm trying to create ONE query which would fetch me the number of occurences on a particular value in a field while keeping duplicates.
For instance let's say i've got the following table
Color......Value
Red.........5
Red.........8
Orange....1
Then i would like to have the following result from my query
Color.........Value.......CountOfColor
Red............5..............2
Red............8..............2
Orange.......1..............1
I know i could achieve this by creating a view first. For instance by saving this expression as qryCountOfColors
Code:
SELECT tblColors.Color, Count(tblColors.Color) AS CountOfColor
FROM tblColors
GROUP BY tblColors.Color;
And then make the following query
Code:
SELECT tblColors.Color, tblColors.Value, qryCountOfColors.CountOfColor
FROM tblColors INNER JOIN qryCountOfColors ON tblColors.Color = qryCountOfColors.Color
However I'm woundering wheter or not I could achieve it without creating the qryCountOfColors.I'm myself into a mental meltdown . I've been playing with the idea of creating of creating a subquery to achieve this but im unable to get to work
Code:
SELECT tblColors.Color As BANANA, tblColors.Value, (SELECT Count(tblColors.Color) AS CountOfColor FROM tblColors GROUP BY tblColors.Color HAVING (((tblColors.Color)=BANANA))) AS Expr1
FROM tblColors;
I am trying to count the number of times a client has engaged with our company. I have a company table, a reservation table, a rapid prototyping table and a project table. There is a one to many from the company table to each of the other 3 tables as can be seen in the attached picture.

Hi
Im trying to run two count functions on one column in sql (access 2003). I need to return two new column, pass and fail. something like this; select count(grade) as pass, where grade>=40 and select count (grade) as fail, where grade<= 39.
my table is student_ID, module and grade:
student_ID Module Grade
0012 history 59
0034 history 34
0045 maths 78
0031 maths 45
0046 spanish 66
what i need is:
Module Pass Fail
History 1 1
Maths 2 0
Spanish 1 0
I have achieved it by running two seperate querys, one for pass and one for fail and then merging them with another query but is there any other way?
stuck with this problem on trying to calculate the aggregate sales totals of a product within a specific time frame. The query that I have built instead divides each sum by date, where it should be grouped according to product instead.
Here are some screen shots as to how it looks in Access. [also see attached ZIP if you don't want to unbreak links ]
[URL]
As you can see, the PRODUCT_ID column is not combining together according to their IDs.

This how my Design View looks.
The SQL for my current query is:
SELECT PRODUCTS.PRODUCT_ID, Sum(SALES.SALES) AS SumOfSALES, SALES.TRANSDATE
FROM PRODUCTS INNER JOIN SALES ON PRODUCTS.PRODUCT_ID = SALES.PRODUCT_ID
GROUP BY PRODUCTS.PRODUCT_ID, SALES.TRANSDATE
HAVING (((SALES.TRANSDATE)>=#9/1/2008# And (SALES.TRANSDATE)<=#12/31/2008#));
Hello, guys. First of all, may all of you have a very cool New Year 2007!
In my MS Access database i have 2 tables: Table1 and Table2. These are related by means of the fields Field1 (Primary key of Table1) and Field2 (Secondary key of Table2). The relation is 1 to Many.
I pretend to count the rows from the Table2 with different Field2 values. Thus, the following query would be an ideal solution:
SELECT COUNT(DISTINCT Field2)
FROM Table2
Unfortunately, the DISTINCT clause is not admitted within COUNT parenthesis. So, what i came up with is:
SELECT COUNT(*)
FROM Table1
WHERE Field1 IN (SELECT DISTINCT Field2 FROM Table2)
It works, but it takes too long to run the main query, where i embedded several subqueries like the one above.
Is there any other way to get the same result reducing the response time?
Thanks for your attention in advance.
I have a report that I'm trying to concatenate some "sum" and "count" data into one line. This is what I have

How can I query the number of occurrences of a string in a field, e.g.:
if a name field has the text: Martin Lacoste
how can I get it to tell me there are two "a"s in the field?
I can use InStr to find one, and make a few more queries to find a few subsequent, but the data I need to search could have 30-40 occurrences of the desired text in a field.
Ideas?
Thanks!

Any way to use multiple count functions in a query with their own individual filters without affect the others?
For example:
SELECT [E&I Table].System, [E&I Table].DeleteRecord, Count([E&I Table].[Status#1]) AS [CountOfStatus#1], Count([E&I Table].[Status#2]) AS [CountOfStatus#2]
FROM [E&I Table]
WHERE ((([E&I Table].[Status#1]) Like "ITR Rcv'd by QA" Or ([E&I Table].[Status#1]) Like "Completed" Or ([E&I Table].[Status#1]) Like "Ready for T/O" Or ([E&I Table].[Status#1]) Like "Reviewed by JVV") AND (([E&I Table].[Status#2]) Like "ITR Rcv'd by QA" Or ([E&I Table].[Status#2]) Like "Completed" Or ([E&I Table].[Status#2]) Like "Ready for T/O" Or ([E&I Table].[Status#2]) Like "Reviewed by JVV"))
GROUP BY [E&I Table].System, [E&I Table].DeleteRecord;
I am trying to count in each column of the E&I table with criteria using WHERE but the problem is when you have more than 1 WHERE it affects the other columns as well... tried a bunch of different ways and I am now having to create seperate Queries than combine them using another Query...

View 3 Replies View RelatedI need a function or way of dealing with a field that may or may not exist.
I am crosstabbing a large database and then building queries on the crosstab. However, the field from which the column headings come does not always have the same data in it as I have to cut the data in different ways (always similar but not always the same). As a result, sometimes I get the error message:
"The Microsoft Jet Engine doesnot recognise [FIELD] as a valid field name or expression"
where a field I was expecting did not appear.
If it was a null value within a field I remove it like this:
iif([Field] is null, 0, [Field])
Is there an equivalent formula for "exists" that will stop my queries falling over when it cannot find the field?
eg iif(exists([Field]),[Field],0)
Any help, guidance or assistance gratefully received!
