DCount And Getting Num Occurances Over A Date Range

Jan 21, 2006

Hi;

Summary: Using DCount in MS Access 97 to output the name of an event
and the total number of occurances per a user input date range.

e.g. the table is called EventData and it is a table of the types of car repair performed, and the fields are:

EventType Date Desciption other Time
======== ==== ============ ====
fix flat 17/01/06 comment.... 101pm
brakes 15/01/06 comment... 504pm
tuneup 02/01/06 comment... 725am
paint fender 03/01/06 comment.. 852am

My issue is to use a subquery for intermediate results and then another query.

I would like the user to enter the start and end dates, and then for output to be:

Output:


EventType Num Occurances
======== ============
fix flat 2
brakes 5


approach 1, use subquery called SummaryQuery:

SELECT EventData.EventType, EventData.Date
FROM EventData
WHERE (((EventData.Date) Between [Type the Start date:] And [Type the End Date:]));

This gives me output of all the events types in the date range and the time.

Then if I query this via:
SELECT SummaryQuery.EventType, DCount("*","SummaryQuery") AS TotalCount
FROM SummaryQuery
GROUP BY SummaryQuery.EventType
HAVING (((EventData.EventType) Between [Type the Start date:] And [Type the End Date:]));


Here I am using DCount to get the num of ocurrances.. but it is not working.
I get the error that "Access cannot find the name "type the start date" "

approach 2, Use only one query:


SELECT EventData.EventType, DCount("*","EventData") AS TotalCount
FROM EventData
GROUP BY EventData.EventType
HAVING (((EventData.EventType) Between [Type the Start date:] And [Type the End Date:]));

for this, I get no output, but the query runs.

Any comments or help with this is appreciated!!!!!!!!!!!!!!!

DCount With A Date Range Greater Than X

Mar 3, 2008

Hi,
The query statement below is meant to extract the number of References with a type code of 'M' on the table tblHDRef, then present it under a column named 'Modified':

Modified: DCount("[tblHDRef].[HD Ref]","[tblHDRef]","[tblHDRef].[HD CodeType]='M'")

This works fine - but how can I add further criteria to this query statement to only count references with a HD Date greater than 03/02/2008?

I tried:
Modified: DCount("[tblHDRef].[HD Ref]","[tblHDRef]","[tblHDRef].[HD CodeType]='M' and [tblHDRef].[HD Date]>#03/02/2008#")

but this didn't seem to work at all. Am I missing something?

Cheers in advance.

Forms :: Using Dcount With Combo Box And Date Range?

Jun 13, 2014

I would like to have a text box display the number of records for a selected title that fall within a selected date range. Been looking around for a while and have this so far;

=DCount("Discussion_Title","Discussions","[Discussion_Title]='" & [cboType] & "' And [Discussion_Date] = Between ([txtStartDate] And [txtEndDate])'")

I get an #Error message. I just threw that together because it describes what I want, but I know there are syntax problems.

Print Date Range On A Report Based On A Non-date Field

Aug 7, 2005

Is there a way to show the earliest and latest dates of a report generated by a non-date field?

E.g. I generate a report based on Food, and it'll list the days that this food is associated with. Is there a way to show the first and last day that appears in this report (i.e. the range of dates that the report shows based on the food selected)

Dcount And Date Field Problem

Jan 3, 2006

I'm having abit of a problem with the DCount function where date fields are involved.

Basically, I have a table - TblMain.
Within that table there is a field -DateRegist. The data type of this field is set to Date / Time - Format short date.

Elsewhere I have set up a form with a text box. The idea being this text box will count the number of 'DateRegist' fields where a date has been entered between two set dates. (There will be four text boxes in total, one for each quarter of the year)

When I use Date() etc in the control their are no problems. However, when I try and use an actual date it all goes pear. I figure it has something to do with it being a date field bit not sure exactly what.

This is what I have so far (don't laugh, I know its miles off the mark but I am trying)

=DCount("[DateRegist]","[TblMain]","[DateRegist]=Between #" & 1/4/2006 & "# AND #'" & 30/6/2006 & "#")

I know I can do four separate queries, each pulling off a quarters data and then draw off the Dcount from each of them but after two days of trying to figure it out I would like to know where I'm currently going wrong - (If you consider doing to four queries will be quicker for the abstraction of the data then let me know but I would still like to know what I'm doing wrong for future reference)

Thanks in anticipation

Modules & VBA :: Dcount With Date Variables

Jul 11, 2015

Im a relative novice with access VBA, and I'm really struggling with using Dcount with date variable. All I want to do is count if a certain date appears in a table. Here is the extract from my code:

Dim WorkoutDate as Date
Dim datecount as integer

datecount = DCount("[WorkOut Date]", "tblworkoutlogs", "[workout date]= " & WorkoutDate)

Whatever dates are in tblworkoutlogs, datecount is still = 0...I've trawled the net and tried many variations of the code but no success!if I change all the date formats to strings in the code and the tables, it works so I know i'm looking in the correct place.

Modules & VBA :: DCount Using Date Comparison

Mar 6, 2015

I'm trying reference a dcount on two fields, one is a string and works fine, the other is on a date which does not.

I've investigated the problem and found a couple of references to making sure I use a # symbol to reference the date but I think the thing that's throwing the comparison out is that the date field stores time as well, even if you can't see it?

Code:
MsgBox DCount("*", "[healthcheck]", "[check_date]=#" & Format([Forms]![MAINTENANCE_FRM]![MAINTENANCE_DETAIL_TBL subform].[Form]![FIRST_HEALTH]) & "#")

I thought should count the records in the healthcheck table that match the check_date field against the first_health field on the current form, but I keep getting a 0 count even though the dates seem to match.

Modules & VBA :: DCOUNT With Date Criteria

I can't get the following DCOUNT working for the life of me: DCount("EmployeeName", "tblAttendance", "EmployeeName = '" & cboEmployee Name. Value & "'" And "AttendanceDate = #" & txtAttendanceDate.Value & "#")I have checked this forum along with Google and there seems to be no easy way to do this? I have tried editing the syntax over and over again. I have been able to run a query and get the desired result in that query; however I am unable to call that result in VBA.

Dcount For 2 Criteria Date Fields?

Apr 19, 2014

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

Counting Occurances Of Months

Oct 9, 2006

Hi

I have a table with a column which has dates in it.

Eg

Column a

01/07/2004
19/07/2004
28/09/2004
06/10/2004
28/10/2004
17/11/2004
24/11/2004
30/11/2004
16/12/2004
10/01/2005
13/01/2005
19/01/2005

I need to count how many records are in each month

Ie 07/2004 = 2
09/2004 = 1
10/2004 = 2
11/2004 = 4
etc

I am using a group by and a count in a query but I think I need some sort of criteria which tells it only to work it out on the month & Year.

Sorry if this is an easy one!! I am not the best at Access but I am a tryer!!!!

Count Occurances Of A Record?

Jun 14, 2007

I am working through a lot of data and this is basically what I'm trying to do.

Let's say we have billed occurances for ABC Pet Store. What I need to do, is to see how many "billed lines" appear in the data. So if there are 3 billing occurances (let's say bill amount greater than zero) - in the data I want the query to populate a "billing occurances" field with "3."

How would I do this?

Modules & VBA :: Date Expression For DCount And Where Open Arguments

Oct 9, 2014

I am getting something wrong but I don't know what - date related.

Take this code for example:

Code:
Dim varDate
varDate = Date
If DCount("RunningNumber", "AllocatedVehicles", "ServiceDate=" & varDate) > 0 Then
MsgBox "Go Away", vbOKOnly
Else
Go on and do the real work
End If
End Sub

The DCount line is being completely ignored, no error message, it just cracks on as though there were no records found (but they are definitely there!) I have tried:

Code:
Dim varDate
varDate = Date
If DCount("RunningNumber", "AllocatedVehicles", "ServiceDate='" & varDate & "'") > 0 Then
MsgBox "Go Away", vbOKOnly

But that throws up a Type Mismatch (which is what I would expect). Then I tried

Code:
Dim varDate
varDate = Date
If DCount("RunningNumber", "AllocatedVehicles", "ServiceDate=#" & varDate & "#") > 0 Then
MsgBox "Go Away", vbOKOnly

And it gets ignored again.

I am having similar trouble trying to open another form using the same field as the open argument, and getting similar results, so it is clearly me that is wrong.

Date Range Based On A Record Date

Mar 21, 2007

I am trying to filter out information for an ODBC query I have written, to obviously make it more concise. Because our data is not set up very logically, a lot of my queries are based on text...but that is another story. My current situation starts with a simple make-table query finding certain data within a date range. This is followed up by another simple make-table query to find other specific data within another specified date range. Then I have a cross-tab query between the two tables to locate all the data that shares the same unique identifiers. My problem lies with trying to only pull information from a certain date range. For example, I want information to be included if the data has the same unique identifier as well as falls within +/- 7 days of the received date (dd/mm/yyyy) also listed in one of the tables. Each record will likely have different received dates so I cannot set it as a constant.

Make sense to anyone? I am not confident enough to play around with some expressions...well it is more I haven't been successful at using them correctly.

All help is greatly appreciated.

Thanks,
Jay

Selecting A Date Range For A Calc'd Date

Jan 13, 2008

I Have a table that I collect data for numerous ID's. One ID may have 5 dates that is was serviced. It is due to be serviced at set intervals which is calculated from the most recent service date. I'm calculating the next service date in a text box with the DateAdd func. =(DateAdd('m',[Cal Freq],[MaxCalDate])) with the MaxCalDate being a Max func in a different text box for selecting the most recent sevice date. I'm trying to update the [Next Due] field in the [Master Asset] table with the calculated next service date so I can do queries on items that are due service within a date range. If I do an Nex Due Expr1: in the queries to calc the next due service date then do a criteria on that Expr1: such as >=[Start Date] And <=[End Date] it states datatype mismatch? Is there a way to select a requested data range on a calculated type date/time? Or How can I update the [Next Due] filed in a different table?

Date Range Within A Date Range

May 12, 2006

I'm trying to figure out how I can set a parameter on my query to search for any activity that occurs within a month, that falls within a date range. Specifically:

Criteria TextBox: 4/2006

Activity Start: 3/6/2006
Activity End: 5/5/2006

I want this activity to show in my query because the time between start and end occurs during the month of April. It's no problem setting this up for a specific date, ie 4/1/2006, but I don't know how to do it for an activity that occurs all days between 4/1/2006 and 4/30/2006..or for one that starts 4/12/2006 and ends 4/18/2006, or starts 4/12/2006 and ends 5/9/2006. etc.

Date Range

Jun 18, 2006

Hi All,

I have a table of data, one of the fields is a date.

What i want to do is be able to have a query that can check if the date falls within a certain range - ie fiscal year and output in another column the fiscal year "code".

Ie: dates between 01/06/05 and 31/05/06 is fiscal year 0506
dates between 01/06/06 and 31/05/07 is fiscal year 0607

Could this query be dynamic so if a new fiscal year begins it would know to make the output the next fiscal year code???

Any help is much appreciated.

Cheers

Rudi

Date Range SQL

Oct 10, 2006

I have two tables: tblClasses & tblSchedule. There are joined by ClassID. For each class in the tblClasses there are several records with date field in the tblSchedule. (So each class stored in tblClasses happens on multiple dates stored in tblSchedule).

I want to create a query (SQL view) that would take two date inputs from a form(date range): datefrom & dateto, and return any class of which FIRST day of classes falls in between those dates.

(Or: how can I add a field to my query called [First day of class] that would basically have the value of the first date from the tblSchedule for the joined classID?)

How To Use A Date Range

AND WGMAHIST_TIMEDTY.TDYEDT >= #06/29/2007#
AND WGMAHIST_TIMEDTY.TDYEDT <= #09/21/2007#
AND WGMAHIST_TIMEDTY.TDYPT = 1
AND WGMAHIST_TIMEDTY.TDYCO = 8

I am obviously doing it wrong because I keep getting an error that complains about the key work BETWEEN.

How can I make this work? I am using MS Access 2007.

Date Range Using IIf Help

Apr 7, 2008

I have a form with a combo box containing the names of the Months. What I want to do is then pass the Month name to a query as a date range. For example, select "May" from cboMonth and the query will check the date field for "between 05/01/2008 And 05/31/2008"

Here is what I have in my query but it does not show any records when I run it:

IIf([Forms]![Form1]![cboMonth]="May",Between #5/1/2008# And #5/31/2008#)

Is it even possible to use this type of an expression in the query?

Thanks......
