Friends,
I have a form with four fields, date1, date2, date3 and date 4.
These have all a mm/dd/yyyy format.
I need to add an unbound control which will count in months and years the difference between the dates.
Ex.
date1: 01/01/1970
date2: 05/05/1980
date3: 06/06/1990
date4: 06/30/2001
Fields date3 and date4 may be blank, therefore the code should consider only counting the first two.
Thanks for any help.
Using MS Access 2000
I'm building a customer management database. Part of which is a table to record details of all members of the main customers family or the household compliment.
I'm currently using a DCount to work out how many people on the table are related to my client, to work out the size of the family.....
=DCount("MemberID","tblHHMembers","CustID = [CustID]")+1
Could I also then count the members of the household that are under 16 years old by looking at the DoB from the same household members table?
I realise that I'd need to ask access to calculate age at the same time as working out if they're under 16 and then count them if they have the same Customer ID - which might need a little more than this single function!
Hello,
I am building a Db that will report against individual transactions. Each transaction will be on a specific day.
Now I will need to slice and dice the data in a number of different ways depending on what the end user wants to see.
Therefore I need to build a date table that will aggregate all the individual days by Week, Month, calendar year, fiscal year...etc.
Being a rookie, I was simply going to build a table that has all the days for the last three years and then the corresponding weeks, months etc in columns to the right.
Because of this design, I will have over 1,000 records. Could I do it differently to keep the size of the table down?
For example use ranges as a cell value (Our week 1 is named "Feb 1st Wk", it is 1/30/06-2/5/06 for fiscal Yr 2006, 1/31/04-2/6/05 for fiscal Yr 2005...etc)
Any advice on this?
Thanks, Paul
Hello to everybody.
I have a problem in calculating the difference between two dates and displaying the output into Years Months Weeks Days. My problem is that dividing the number of days by 30 and requesting an integer is not accurate enough. I have looked at Pat and Jons examples shown in these threads
http://www.access-programmers.co.uk/forums/showthread.php?t=67472
http://www.access-programmers.co.uk/forums/showthread.php?t=89051&highlight=calculating+number+months
which either method would suit me as the accurate answer is what I am after.
My problem is that not all of my records would have a start and end date. Therefore both examples would result in an error.
Can anyone please give a hint on how to perform the calculations on those fields which have dates recording the results but ignoring those fileds which do not have a start / end date.
I am having a bad day and I'm sure the answer is so easy that I am going to kick myself but having played around with the modules by limited knowledge is not enough.
Many thanks in advance
Ian
Find the difference between two dates is simple if you're simply looking for the number of days between them. However, if you're looking to express the difference in a bit more user-friendly way, you can use the following code to calculate the difference in years, months, and days. The code accounts for zero values, plurals and the Oxford comma. Further, it automatically sets the later of the two dates to the End date, so the dates can be used interchangeably.
Examples:
June 4, 2010, July 3, 2012 returns "2 Years and 29 Days"
June 4, 2010, July 5, 2011 returns "1 Year, 1 Month and 1 Day"
June 4, 2010, June 5, 2010 returns "1 Day"
Code:
Function DiffOfTwoDates(dtmDate1 As Date, dtmDate2 As Date) As String
' Written by Will Knapp, Freelance Access Developer, 2013
Dim dtmStart As Date, dtmEnd As Date
Dim strDiff As String ' Resulting String
Dim yDiff As Integer ' Year Difference
Dim mDiff As Integer ' Month Difference
Dim dDiff As Integer ' Day Difference
Dim CommaLoc As Integer
[code]....
I am wanting to get an expression that will return the difference in years and months between 2 dates. Specifically, I want to know peoples ages in years and months based on a person's D.O.B and todays date. I have managed to do it in years:
Expr1: DateDiff("yyyy",[TBL_EmployeeDetails]![D_O_B],Date())
and in months but I would like to know how to return the difference in years and months.
I am trying to create a parameter query to return dates that have 2 years remaining.
For example I have dates for when mortgages expire, and I want to recognise the dates that have two years remaining using a parameter query but I can't figure out if I use DateAdd or DateDiff.
Okay, this is gonna be weird :o What I'm looking to do is count the dates a preticular training task was accomplished. However, I do not want the dates that are expired to be counted. I will be running this off of a quiry that shows the "due date" of each task. I really have no idea where to start :confused: . Many thanks, Tim

I have a report that lists a medical record number and under that number is a list of dates that the patient was seen. I need to know how to count the number of times the patient was seen. Example:
Medical Record #
12345678
Dates Seen
1/1/07
1/2/07
1/3/07
Total Days Seen: 3
So: I need to know, on my report, how to count the total number of days seen. Thanks for any help.
P.S. I'm learning so much from this forum, thanks!
My report has certain patient's listed. Under each patient there are different dates that the nurse visited these patients. I need to count how many days the nurse visited ALL the patients. the problem being that she will see many patients on the same day. As an example:
Patient Smith
1/1/07
1/5/07
1/9/07
Patient Jones
1/1/07
1/5/07
1/20/07
1/31/07
I need to know the number of distinct "days" during the month the nurse was visiting patients. The example above should show that the nurse had visited patients 5 days out of the month.
I have a table that lists computers I want to know the age of them for replacement purposes. I am using this function to populate a textbox on a form that updates my table. the results I am getting is a negative whole number I would like to get a positive number with one decimal place. so if computer was shipped September 24, 2010 my textbox would say 3.5 not -3
Here is my function
Code:
Private Sub Form_Load()
Dim theDate As Date
Dim age As Integer
theDate = Nz(Me.compDate.value, 0)
If theDate > 0 Then
age = DateDiff("yyyy", Now(), theDate)
Me.compAge = age
End If
End Sub
I would like to count the number of working days between two dates, NOT the calendar days, if the workers only work Monday thru Thursday. I know we could use the DateDiff function, but HOW do I count excluding Fridays, Saturdays, Sundays?
Thank you for your help.
I have an activity report which has multiple entries for the same date by club members. I have managed to build the database:
2 Tables
2 Queries
2 Forms
1 Report
Which list attendance's and activities by Member and Date and Prints each one starting on a fresh page..What I wish to do is count each Club Members total days attendance. I have tried using the Totals button but I don't know enough about expressions to get it to count multiple dates as 1.
Everywhere I have looked can tell me how to count between dates, around dates, workdays in a year etc. etc. etc. but none give me multiple dates the same counted as 1.
Hi, I searched the forum for this but the only thread that came close to what I was looking for was this.
http://www.access-programmers.co.uk/forums/showthread.php?t=125240&highlight=null+chart
Basically I have chart in a report thats based on a query that counts the amount of entries per month between two dates inputted by the user.
It all works fine but the chart that is based on the query only shows months that have an entry.
Eg if it counts all dates between the two dates and say the only month that has an entry is July, the chart will only show July. What I want is the other months to show (Null values) as zero, so every month shows. I'm probably missing something basic but can anyone help?
[TextPriDate] is the start date
[TextPriDate2] is the end date
This is the query code (QryDate)
SELECT
tblMain.ID1, tblMain.Dt
FROM
tblMain
WHERE
(((tblMain.Dt) Between [Forms]![frmSwitchboard]![TextPriDate] And [Forms]![frmSwitchboard]![TextPriDate2]));
This the code from the chart in the Report
SELECT
(Format([Dt],"MMM 'YY")) AS Expr1, Count(*) AS [Count]
FROM
QryDate
GROUP BY
(Format([Dt],"MMM 'YY")), (Year([Dt])*12+Month([Dt])-1);
Thanks
I have 2 dates that I need to count between. Easy enough just use the datediff right? Nope cause it won't count just the 5 workdays. I researched and found that the "w" in the function doesn't work the way I need it to. I found lots of code to make a module that will do it for me and they all include having a holiday table. Right now I don't need a holiday table I just want the simple dates in between.
View 2 Replies View RelatedI'm creating a database for my wife to use in her work, one of the fields is dates visited and the user should enter "00/00/0000, 11/11/1111, 22/22/2222, 33/33/3333" in this format. The field is a large text format because there could be anything from 1 date to hundreds. What I need to be able to do is in my query I need to enter 2 dates and have access return a how many dates exist between those 2 date values. eg It will pop up a box asking for start date and then another asking for end date and then it has to return the count total of how many dates exist between those two date values. I don't know VB and have had only basic training in Java and C# none of which involved Access. The only way I can think of doing it is to have access count the number of commas within the date field required but I don't know the formula required assuming it can even be done.

rowsource is a query called qryVacations
the query should calculated two things
1 - the difference between start_vac and End_vac in days to calculate the vacation period and put the value in field called Period (working well)
2-the work days which the period between the last day in Previous record (End_Vac) and the (Start_Vac) in the next record (didn't work)
the result is the difference between (End_Vac) and (Start_Vac) in the same record which i don't want

I have a report due the first of each week in which I need the cases open and cases closed for the previous week, the week two weeks prior and the 2007 and 2006 year to date on two different types of cases. I have a case management table with a field for Type of Case, date assigned and date closed that I uses in my queries. Presently I have two query, one that generates only Type 1 cases from the Case Management Table and another for Type 2. I then use the Type 1 Query in another query that limits the results for Type 1 cases to those opened last week, one for those open two weeks ago, one for 2006 YTD and one for 2007 YTD. In these 4 queries I have one field [Type of Cases] and I have the query count. I then do this for Type 2 cases and then go through the whole process to do Closed Cases. All my queries have criteria to automatically filter the dates to the time periods mentioned above. I then have one report query that I put all the number in for my report. This query has 16 fields with the numbers for each period, last week open and closed, 2 weeks open and closed, etc. I then generated a report that takes these numbers from my report query and puts it in a report format automatically. As you can imagine this takes some time to go through each query to generate these numbers, so I was wondering how I may do this differently. Also, I have experienced a problem when a field produces no records I get a blank sceen with nothing under the Count of column and get the same thing for my report. How can I fix this.

I'm a bit confused with date codes. What I'm try to complish here is that how to add years and months from separate fields to text box, where's difference between two dates as an years and months? So basicly first I read year and month values from text boxes to a integer and then I'm going to add them to somewhere at last, but I'll get like 1 year and 14 months for result so, could you hit me with some tips or tricks what I should try out.
I'll approciate your time to help me out with this and thanks for advance. =P
Firstly, when designing tables, how can I format Date/Time to just the Year? I've tried syntax yyyy, but when I enter a year after opening the table, I get a type mismatch error.
Secondly, providing I have the correct custom format for Year, how can I enter the following dates?
1744-1745
Circa 1925
Before 1690
1800s
And would I be able to run queries on them, showing the dates in ascending order?
Any help would be much appreciated!
Hi,
I would like to be able to run a query that lists the number of years members have been subscribing (up to the current year).
i.e. to show the year he joined, and how many years he has been a member (shown as a number).
Is there a way to do this easily?

I have atable the is storing ID, attendance_year and meeting code. Iw ould like to query the table and identify the IDs that have 10 consecutive attendance years no matter when it may have occured. So IDs have more than 10 row of data but not necassrily 10 years in a row.
How can I do this?

I’m after some database advice. It will probably be something simple I can’t see for the wool…
I’m putting together a database that describes specifis small area geographies (Scottish Census output areas). For small area there will be various training category variables with associated counts and a general cost for all training in that geography. On its own this isn’t really a trouble but the database will grow over time with the same data (more or less) appearing each year to add to the database. I have a master geographical index that is used to aggregate small area data to higher areas so I could :-
- have a series of year based tables linked through the small area field and queried on a year look up basis.
- store each years data into the same table as the last and use a year identified to separate the records
- add new fields for all variables for each year across one table although once the number of fields reach 255 or so it would fall to bits.
I think the third is the worst option but I really would be grateful if anyone had any thoughts you could share with me on the best design approach to take.
Any help gratefully received!
Thanks...
