Using DCount To Count Fields On Query
Jan 3, 2005
Good day:
Code:
=DCount("[DEPARTMENT]","[Query1]","[DEPARTMENT]='ENGINEERING'
I have a query with these fields: DIVISION, DEPARTMENT.
The DIVISION fields are populated with undergrad or grad. The DEPARTMENT fields are populated with ENGINEERING.
I wish to count the occurances of undergrad engineering and count the occurances of grad engineering and return the values in separate text boxes.
Any ideas on how to count occurances of TWO fields?
Thanking in advance.

HELP PLEASE!!! There are two fields in my form that need the following relationship:
1. When I enter 1000 in my "spec no" field in my form, I need my "Number Field" to enter a "1"
2. When I enter 1000 in my "spec no" field in the next record, I need the "Number Field" for this record to enter "2" but "1" to remain on the first record.
3. If I enter 1001 in my "spec no" field in the next record, I need the "Number Field" to enter "1"
4. Continue this logic for all records without modifying the previous "Number Field" record.
I was told there was a way to accomplish this using DCount or Count function. Maybe there's an easier way??? Any help is greatly appreciated!! TX!

I have a query that creates counts of fields based on the data in other fields, basically it tells me that in a table there are two entries with value ABC????? and three of DEF????? , the query works perfectly.
When I create a form to display this data and base the form on the Query I keep getting a message box asking for the ID (key field) from the base table.
If I type * in the box (to denote all values) and press enter I get the results expected.

DCount function.
Code:
Me.ImprovementNotice5DayCount = DCount("[txtReferralReason]", "qryRTOFileReferralPopupCount", "[ComplianceTargetDate]-[DateNow]<=5")
I am not sure where I have gone wrong.
What I would like Dcount to count are those dates in the ComplianceTargetDate form control that are <=5 to the DateNow form control.
I get a count of 3 when there is only one. I may have the syntax of the Dcount wrong.

I have this query:
ID Attending Trauma RN Date
1 A No Yes 1/1/12
1 A Yes No 2/1/12
1 B No Yes 1/1/12
1 A Yes No 3/1/12
1 B No Yes 6/1/12
I merged this query into a report to give the count of each attending equaling yes only. I am using this:
=DCount("*","qryMainJan-Jun13","[PeripartumHysterectomy] ='Yes' And [Text30] = ID")
The goal is to show each attending on a separate page with count on text box
The issue I am having is I can't show the correct total in one page for each attending. for example I am showing attending A twice for trauma with total 1 for each page. I need to show attending A with total 2.

I have a report that I am trying to complete based on several queries. I am trying to count the number of records based on certain criteria and using the following DCount.
=DCount("[Calculated time]","IPG1","[Calculated Time] <= 0.04" And [Ship-to party] In ("SN00207PJZ","SN09162XXX","SN09324XXX"))
I want to count the number of IPG1 records that are under .04 and have the Ship-to party of the ones listed. I have tried everything that I can think of to get it to work but can's seem to get it to. I figure it's something easy but I don't see it.

I need to check the combination of a text box and a combo box that are bound to the same table for duplicates and then give a message box telling of the existing records. The 2 fields are set up as a compound index so access displays a generic message but I am trying to customize the message without doing it through error trapping (because I want it earlier in the processes on the form).
I am trying to us Dcount as follows but this is not working. It seems to be checking for either rather than a combination of the 2 fields because I get my message if either the Description OR the Group is duplicated (both of the text box and the combo box can have duplicates and it is only the combination that is singular) .
If DCount("[Description]", "[ItemTBL]", "[Description] = '" & Description & "'")
And DCount("[Group]", "[ItemTBL]", "[Group] = '" & Group & "'") > 0 Then
MsgBox "This Item is already in the database.", vbExclamation, "Already in Database"

With a form with two fields one is a date field formatted as short date and the other is a lookup combo box that I use to lookup predefined times and is formatted as short time. The date and time are stored in the same table as date/time in separate fields. I attempted to use Dcount, and get syntax error missing operator. Below is one of a hundred that i have tried after scouring this forum and the net. I ended up converting the Appt_Time field to a text field in the table to eliminate one date field but still got no where.
Code:
Private Sub Appt_Time_BeforeUpdate(Cancel As Integer)
'Check table for duplicate
If DCount("[Appt_Time]", "tblexams", "Appt_Time= & Appt_Time & And [Sch_Date] = #" & Sch_Date & "#") > 0 Then
'Message box warning of duplication
[Code] ....

I am having an issue using DCount to validate against 3 fields within my database. I have a booking form which contains a Staff member, viewing slot, and Viewing Date which is used to book property viewings.
I want the form to check that the booking doesn't already exist when the process booking button is pressed.
I am using the following statement:
Code:
If DCount("*", "Viewing", "[Staff_ID]=" & Me.[Staff_ID] & " AND [Viewing_Period] = " & Me.Viewing_Period & "' AND Viewing_Date = '" & Me.Viewing_Date) & "'" > 0 Then
MsgBox "Cannot book, booking already exists", vbCritical
End If
I always get the error "Syntax Error (Missing Operator)".

I am a beginner with aggregate functions.
I have two tables, one describing parts, and one describing assemblies that use those parts:
tblParts show all the part descriptions, including fldPartNumber.
tlbWhereUsed shows zero or more fldAssemblyNumber records for each fldPartNumber.
I want a query that shows, for each record of tblParts, the number of assemblies that use that part. I specifically want to do this with an aggregate function:
DCount("*","tlbWhereUsed ","[tlbWhereUsed].[fldPartNumber]=[tblParts].[fldPartNumber]")
but I don't know where to put this function call in the query grid.
(I do not want to do this in VBA, if I don't need to).
Thanks in advance...

Below is the Field data I have in a query. This allowed me to get a count of forms for the current month. I think it is giving me a count of forms for both October 2004 & October 2005. Up until this month I did not have any data covering the same month of both years. Could this be what is happening and if it is how do I change my field data to ensure it is current month and current year only?
FORMS: DCount("[Date_of_Change]","all_trucks_table","[FORM #]=true AND Month([Date_of_Change]) =month(now)")

I have a DCount Ranking query that worked fine last week and with this week's data came up with a glitch. Here is my DCount statement in the query:
Rank: CInt(DCount("*","qry_YTD_Territory_Totals","[Total]>=" & [Total]))
Here is my result which you can clearly see is not a tie.
Territory Total Rank

I have a form that is linked to a query by its Record Source.In one of the Text boxes I want to appear the number of rows in the query where Days = 4 so I thought I would try to use DCOUNT as the Control Source for the Text Box. However every expression I try for DCOUNT throws back error? or name?. How to sort my code?
=DCount("[EPISODEUNIQUEKEY]","1-12 Show Records by Date Range","[Days] = '4'")

I have a table [Control Table] with the fields [Date signed] and [outcome] date signed is formatted as dd/mm/yyyy and the outcome field is a drop down with the options granted, not granted ect
I am looking for a way to present the data using specific date ranges.
I have found 2 possible avenues;
Dcount in a select query:
w/c 01/04/2014 GRANTED: DCount("[Date signed]","[control table]","[Date signed]>=#04/01/2014# And [Date signed] <=#04/06/2014# And [Outcome]='Granted'")
w/c 01/04/2014 Not GRANTED: DCount("[Date signed]","[control table]","[Date signed]>=#04/01/2014# And [Date signed] <=#04/06/2014# And [Outcome]='Not Granted' And [Reason not granted]='Assessed'")
w/c 01/04/2014 Discharged: DCount("[Date signed]","[control table]","[Date signed]>=#04/01/2014# And [Date signed] <=#04/06/2014# And [Reason not granted]='Discharged'")
etc...
But I would need to create the multiple queries 52 times each for the different count value per week
My 2nd option
I have looked at crosstab query, but I cant find a way for it to list the specific dates I need it to query e.g from
01/04/2014 - 06/04/2014
07/04/2014 - 13/04/2014
14/04/2014 - 20/04/2014
etc...
Any tips on Data analysis? I have been able to perform the task previously in excel using If statements but we are now moving to access.

I'm building a health data system that stores data from health tests as follows:
[test01], [test02], [test03],.........[test25], etc etc.
Each of these tests comprised of a "Pass"/"Fail" value.
Now, i'm building my queries for a feedback report to hand over to the client that is based solely on the 1 single client record. In other words the queries are designed to return only 1 single data record to be placed in the client report where the based on the corresponding [TestID].
So within this 1 data record i want a query to count the number of times "Pass" appears in the test fields?
ie count([test01] [test02] [test03] [etc] [etc], ="Pass")
As there are some 40-50 [test##] fields in this one test battery i don'y particularly want to go back and code an IIf statement for each component if i can help it.
Many thanks in advance for any tips.

Hey,
I'm currently working on a database for my school project.
Currently, I have a table:
Job:
Contractor_ID [Foreign Key]
...

Wages:
Contractor [Contractors.Contractor]
Jobs_done [counts the number of rows from Job that has the Contractor_ID equal to the Contractor_ID specific to Contractor (above)]
Eg.
Job:
Contractor_ID
1
2
3
2
1
4
Contractors:

Hi there. Im trying to work out how I can count the dates in my database per month. What ive done is created an unbound box with an sql statement
SELECT Count([tbl Main].[Date of Call]) AS [CountOfDate of Call]
FROM [tbl Main]
HAVING (((Count([tbl Main].[Date of Call])) Between #4/1/2006# And #4/6/2006#));
When I select the totals button to count the records 0 are pulled out.
Does anyone know if im doing something wrong here. As always im sure its quite simple..

Hey all,
I'm having a hard time getting the output below from a query and was wondering if anyone would be able to reproduce this. Basically I'm trying to retrieve products that have more than 5 sales on a specific date and the retailers they sold at. I have the following simplified table.
Table name: SALES
PRODUCT RETAILER SALESDATE
---------------------------------------
PRODUCT1 COMPANY1 10/10/07
PRODUCT1 COMPANY2 10/10/07
PRODUCT2 COMPANY1 10/10/07
I am trying to find which products had more than two sales on the same date, and retrieve the product name, the retailer and the sales
I.E THE ABOVE TABLE WOULD PRODUCE
PRODUCT SALESDATE RETAILER
--------------------------------------
PRODUCT1 10/10/07 COMPANY1
PRODUCT1 10/10/07 COMPANY2
I've been able to only get the first two fields successfully by using
SELECT PRODUCT, SALESDATE
FROM SALES
GROUP BY SALESDATE, PRODUCT
HAVING (Count(PRODUCT)>=2);
MY problem is getting the retailers to appear also. Any help would be appreciated.

Morning All!
Boss-Man has a db (humongous) that (along with a zillion other things) tracks which specific tasks have been completed, who has done it and when did they do it.
All tasks will eventually be completed by all employees.
He's got a query that returns all of the dates on which each task has been completed, using each TASK name as a field.
The short version below shows the TASK1 was completed on 1/1/07, 2/7/06 and 2/17/07, TASK2 was completed on 01/05/07,by 2 people on 2/15/07 and again on 02/28/07 and so on.
TASK1***** TASK 2***** TASK 3 ***** TASK 4
1/1/2007 *** 1/5/2007*** 1/13/2007 *** 1/2/2007
2/7/2006 *** 2/15/2007 *** 1/7/2006 *** 1/15/2007
********** 2/15/2007
2/17/2007******
********** 2/28/2007 ********* 2/28/2006
What he would like to do is be able to show how many tasks were completed in any given week, such as:
WEEK ENDING # TASKS
01/06/07 3
01/13/07 1
02/17/07 2
Looks to me like you'd first have to identify the possible WeekEnding dates and then try to total across all the fields, but I've not got a clue how you'd do that.
Is there an easy way to "query the query", work with Week Ending on Saturday, and get the info he's looking for?
Thanks,
BeckieO

Hey Guys,
I’ve attached a zipped example of the problem I am having with customised navigation buttons.
In my main database the form “subfrmPersonsContact” works perfectly. I have exported it to a new database and now the customised record count fields do not work at all – they are in fact blank even though the navigation buttons do still work.
The code running the form and the record count fields is listed below – I have no idea why it’s not working.
Any help would be greatly appreciated.
Cheers,
Rusty
