I am trying to write a query that will return all records whose field expiration_date meets my criteria. The criteria is
If expiration_date - 5 years < today's date then.... do you subtract the total days? months? Any help would be appreciated.
Thanks in advance,

Hi there. I'm just jumping into Access and have the following question. In my Purchase Order Table, I have a date field calcualated as text, i.e. "01/12/04". I need to convert this to a date format in my queries so I can do calculations, i.e. 01/12/04 - 01/05/04 = 7 days. Can someone help me with how to convert this text date to a date format. Sorry if this is an easy question. - AJS

I would like to manipulate some date information. I have a start date field and an end date field and I would like to draw up a schedule for payment where the Acess takes the finished date and the start date to get total days appart then devides this by a value set by the operator. say If the operator wanted 6 paymes then my total days would be devided by 6 giving me the number of days to add on to the start date. Then with these dates a schedule is made up and the code I have tried looks something like this.
Dim valuation1 As Date
Dim valuation2 As Date
Dim valuation3 As Date
Dim valuation4 As Date
Dim valuation5 As Date
Dim valuation6 As Date
Dim valuation7 As Date
Dim valuation8 As Date
Dim valuation9 As Date
Dim valuation10 As Date
Dim valuation11 As Date
Dim valuation12 As Date
Dim startdate As Double
Dim findate As Double
Dim valcounter As Double
'retrieve start date and end date
startdate = CDbl(Me.Start_Date)
findate = CDbl(Me.Completion_Date)
'calculate evaluation periods
Dim valCount As Double
Dim valDays As Double
valCount = CDbl(Me.Valuation)
valDays = (startdate + ((findate - startdate) / valCount))
'Work on entering valuation dates
Do While valcounter < valCount
Select Case valcounter
Case "1"
Me.valuation1 = startdate
Case "2"
Me.valuation2 = startdate
Case "3"
Me.valuation3 = startdate
Case "4"
Me.valuation4 = startdate
Case "5"
Me.valuation5 = startdate
Case "6"
Me.valuation6 = startdate
Case "7"
Me.valuation7 = startdate
Case "8"
Me.valuation8 = startdate
Case "9"
Me.valuation9 = startdate
Case "10"
Me.valuation10 = startdate
Case "11"
Me.valuation11 = startdate
Case "12"
Me.valuation12 = startdate
End Select
valcounter = valcounter + 1
startdate = startdate + valDays
Loop
' this value is to test the interval period
Me.tdays = valDays
I am new to vb and so ths code is not going to be the best or anywhere near but any help would be great.
Thanks
Hi
I was wondering if somebody could help with a problem I have come across. I am currently developing a database for a small charity that I work for. The aim of the database is to record when staff undertake counselling.
I have created a query that calculates the current age of a client in the database uing the following expresion:
Age: Date()-[Date of Birth]
The Date of Birth is formated as a Short Date
In the query I have set the format of the column in the query to 'yy'. This then just displays the age of a client. This work fine apart from ages which are less than 30. If the age is less than 30 e.g. 29 it displays the date as 1929.
Does anybody know how I might be able to solve this or an alternative way in which to calculate dates and display it as 'yy'. (Its been a few years since I last work with access so skills a little rusty)
The reason behind the yy is that the monthly & yearly stats have to group by age ranges.
I am using Access XP (2002) SP2.
Many thanks in advance

Hi
I have a field for 'deadline' date and I need to show all records where the deadline date is within 7 days of todays date. (Obviously todays date will change daily...)
I have tried subtracting the date from todays date but it doesnt work.
All help appreciated, thanks

I am trying to work out the time span in days between the day I archived a record and the current date. In simple terms it would look like this:
Me.TimeSpan = Now() - Me.ArchiveDate
Now I know this isnt right, cause I tied it! Can someone put me in the right direction please.
Hi Guys,
Just a quick request for a bit of help.
Tries a few things but didnt work.
I have a form which has an employee start date.
What I need to do is work out the holiday entitlement of each emplyee.
The math behine this is, if they have been here less than a year,
we do the following.
20 Days holiday entitlement per year, Divided by 52, then multiplyed by the ammount of weeks remaining in the financial year.
eg, (20 / 52 = 0.384615384) * 31 = 11.92
So they would have 12 Days holiday entitlement.
But if they have been here for 12 months or more, they are entitled to the full 20 days holiday.
How would I express this as an expression or query or VBA to calculate this.
I just cant figure it out, especially the if been here 12 months or more.
I have the start date, in a tbl called tbl_employees if that helps. ( also in the form frm_employee_details )
Our financial Year runs from the 1st December - 31st November
Thanks in advance for any help / advice

Several questions here, trying to lead up to the easiest code...
First is I have a table with some dates, and I need to do some date calculations, but one of the dates I need will vary. So I was thinking of having a parameter ask for it. Is this the best method?
Second, then once I have this date in, I'll need to have it subtract from another dated reference in the table to figure out the numbers of days difference. e.g. 05/31/06 - 05/01/06 = 30 Can you get two dates to subtract like that and come up with a general number field? If so, then will the dates have to be text, converted to numbers, or can stay as dates?
I've tried several methods and have been quite unsuccessful in each attempt.
Thanks
Hi,
In MS Access i'm trying to calculate the difference between one date time to another. for example
26/04/2007 09:00 am
07/03/2007 10:30 am (Current date time)
This should work out the:
days
hours
minutes
seconds
I did want this to be shown on a form
Thanks
Hi there
I need to perform a query that works out how far in advance people book holidays. I have the arrival date and also the booking date, and I think I should be using DateDiff. However, I tried to put it in an existing query and it hasn't worked:
SELECT Bookinfx.[Park Name], Bookinfx.[Accom Type], Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings, DateDiff("d", [Booking Date], [Arrive])
FROM Bookinfx
GROUP BY Bookinfx.[Park Name], Bookinfx.[Accom Type], Year([Start Date])
HAVING (((Year([Start Date]))=2004));
Any help most gratefully received!
I am building a database and in it I need to do date calculations. Without too much detail I input a date based on the built in calender from the date/time field and based on that date I need to have the following data returned into other individual fields: 6 months from that date, the days until that date, 2 months from the date input, 4 months from the date input, 5 months from the date input, 60 days from the end date, 45 days from the end date, 30 days from the end date, and 15 days from the end date.
Example: I input "Sep 10, 2015" and I would get "Mar 10, 2016", "181 Days", "Nov 10, 2015", "Jan 10, 2016", "Feb 10, 2016", "Jan 10, 2016", "Jan 25, 2016", "Feb 9, 2016", "Feb 24, 2016".
I have read through websites regarding date calculations within Access but I cannot find the specifics for the application that I need.
I tried this Between (Date()+7) And Date()
But was wondering how do I write this in an IIF statement.
I want to get a text field going for example:
IIF Between (Date()+7) And Date() THEN "Certification Alert"
I need to calculate (in a query) the Actual Time of a job. I have the start date, start time, end date & end time (all separate fields). This seems to works ok by subtracting the start from the end.
Then I need to calculate the Estimated Time (time it should have taken). This is done by taking the Quantiy divided by the Rate-Per-Hour. This seems to work out ok in the Query, e.g., 101000 / 15000 = 6.66667 hours. But when I display this result in a report as a "Short Time", I get 16:00 instead of 6:40. How can I get the correct display?
The other problem is that I need to divide the Estimated Time by the Actual Time. This also gives me wierd results - I suppose because one is a decimal format time and the other is a "Short Time" format. How can I get the correct answer?
I need a query that will relate values to given date ranges. For Example:
Table: TaxTypeRange
Values:
TaxType; FromDate; ToDate; Contact
W2; 1/1/15; 3/31/15; Tom
1099; 4/1/15; 6/30/15; Tom
W2; 7/1/15; 12/31/15; Tom
Table: Bills
Values:
Contact; BillAmount; BillDate
Tom; 1000; 3/31/15
Tom; 1100; 4/30/15
Tom; 1200; 5/31/15
Tom; 1300; 6/30/15
Tom; 1400; 7/31/15
Requirement: For every period where the TaxType = W2 the query should multiply the Bill amount by 1.20, so the result should be something like this:
Query: BillsAndTax
Values:
Contact; BillAmount; BillDate; TotalBill
Tom; 1000; 3/31/15; 1200 (TaxType = W2 so 1000* 1.2)
Tom; 1100; 4/30/15; 1100 (TaxType = 1099 does not apply 1.20)
Tom; 1200; 5/31/15; 1200 (TaxType = 1099 does not apply 1.20)
Tom; 1300; 6/30/15; 1300 (TaxType = 1099 does not apply 1.20)
Tom; 1400; 7/31/15; 1680 (TaxType = W2 so 1400 * 1.2)
Not sure how to set this up the right way.
I have solved the problems getting values on the subform. I have not in getting values on the subform.For instance, on the one titled phone use the formula in the tutorial is:
=[sbfCustomerRoomUse].[Form]![txtTotalPhoneUse]
#Error results when the doc is put into a form mode.
Now when I input each value in the equation above separately.I still get no entry.
For " = sbfCustomerRoomUse" , I get #Error;
and for "= txtTotalPhoneUse", I get #Name.
CustomerRoomUse and txtTotalPhoneuse are from the subform that was dropped into the customer form in a previous step. It shows that explicitly when designed sbfCustomerRoomUse on the main that CustomerRoomUse come from a subform. This does not seem to need to be done with txtTotalPhoneuse, and I am not sure why. Neither one gives me a desired calculation result.
I have a table with the following logical structure:
Name...Number eaten of apples......Number of eaten oranges.....All fruits
Mike...............3.............................. ..........4...........................7
John...............5.............................. ..........3...........................8
Peter..............2.............................. ..........2...........................4
Phil.................1............................ ............4...........................5
Question 1:
Can I calculate in a query sum totals for apples (or oranges or all fruits)
eaten by Mike and Peter together and ignore John and Phil?
Question 2:
How can I get sum totals for everybody excluding just Peter? Or Peter and Phil?
Your help will be very much appreciated!

I would like queries to do some calculations for me based on a field. The field in the form is a combo field and the user can choose either 1, 2 or 3. Based on the selection, I would like queries to generate some numbers for me.
This is what I have in mind but its not working.
Code : TEST RESULT: If([tlkpTEST].[RESULTID])=1, ([tlkpTEST].[RESULTID])*2, 100)
I am designing a database in Access 2010 to handle customer discounts. The problem I am facing is that the discount can vary by customer. One could be a straight percentage based on certain sales totals, even the percentages can vary by customer, and some customer discounts are tiered. I was hoping there was a way to handle all through one query, because there are so many variations, it would require several queries if I separate by each calculation available.
Is there a way to set up a table listing the customer and their corresponding calculation expression then running a query using that table and the sales data table to do all the calculations. Or is there another way to handle this level of complexity in Access? The end result I would like is one data set with each customer and their calculated discount.
I have an odd problem that has stumped me for several days. I'm working on a form that contains a chart. The chart is based on a query, which is based on another query, which is based on a table. In the top query, I need to put some calculated fields that operate on other fields. But when I try to multiply two fields together, I get Null. I'm pretty confident that the fields I'm operating on are numerical.
The fields of the query should be:
MaxOfEverInSchool
MaxOfSurvivalToGrade
MaxOfEverInSchool
With these being the calculated fields:
MaxOfSurvivalToGradeCum: MaxOfEverInSchool*MaxOfSurvivalToGrade/100
MaxOfCanReadCum: MaxOfEverInSchool*MaxOfSurvivalToGrade*MaxOfCanRea dCum/10000
Any insight would be greatly appreciated--I just can't understand why Access would suddenly refuse to do math.
I am building an Access database for a client. It is an employee staffing database. With that being said they would like the ability to automatically populate the "T2PPCD" date field based on what is entered into the "Report Date" field. (Same table)
The date is the Monday after 180 days from the report date.
I already know how to get it to auto fill 180 days from the "Report Date" but I'm not sure how to tell it to give me the Monday after 180 days.
I'm trying to get my "IncidentDate" field to autopopulate two other date fields to a few days from the "IncidentDate". The other two date fields are "ContainDueDate" and "RootDueDate". I'm trying to accomplish this on my "Test CAP Form"
I tried using the following in the BeforeUpdate of "ContainDueDate" and received a complier error: expected =
Code : DateAdd(d,2,[IncidentDate])
so I removed the parenthesis and nothing happened
Code : DateAdd d,2,[IncidentDate]
I even tried redoing it in the AfterUpdate of "IncidentDate" and nothing happened either
Code : DateAdd d,2,[ContainDueDate]
I'm not sure if I'm even using the right function to get what I want.
I've inherited a database into which the user (not me) is entering essentially the same Date data twice: field 1 contains 6/19/2014 and for field 2 they enter June-14 (the month and year from field 1).
I suspect there should be a way to derive and then reformat the display of field 2 based on the contents of field 1, such that the user only has to enter the first. Is this true? If so, how?
(I know there really is no need for the 2nd field, but existing reports and queries are built around it -- so for right now, I'm just trying to eliminate the duplicate data entry)...
I have a report that displays simple date fields. One of the fields is "lease execution". On the report, I want "lease execution" to display differently depending on the date the report was run.
So:
- If the "lease execution" date is more than 120 days away from today, I want it to display as Q YYYY.
- If the "lease execution" date is between 120 and 90 days away from today, I want it to display as MM/YYYY
- If the "lease execution" date is 90 days or less away, I want it to display the normal date MM/DD/YYYY
I was thinking I would need to do DateDiff() to figure out an amount of days that's between Now() and [Lease_Execution]. Then based on that amount make the report show it differently. Pseudocode would be: if DateDiff() = 40, then display [lease_execution] as MM/DD/YYYY
I am creating a repayment schedule (as a report) and I want to display a series of fields as a column which return (show) a date one month after the date in the field above.
The first repayment date field (Line 1) will show a date one month after the loan was paid out. the Next field below will show the date one month later.
I can't simply insert the "Date + 30" because that would get out of since over the year. If the loan was issued on say the 15th of January, I need the first field to display 15th February and the next would be .... 15th March.... Yes - You've got it!
Now I could do that in Excel, but I don't know how to get Access to do it.
I am building a database to track contract of employees so that I can know which contracts are valid and which are expired.
My table has the following fields:
ID (Primary key)
Employee ID (Foreign key to link to the employee table)
Start_Date
End_Date
Status (Either valid or expired)
Challenge
I want when I enter the end date, the system checks the end date against the current date and fills in the status field with either valid or expired as appropriate. For instance if the contract end date is March 10,2016, the status must be filled in the word valid.
We use access to enter our service tickets in at work.What we have are three date fields.
Call Date
Start Date
End Date
We are 24/7 operation.Currently all 3 just autopopulate with the current date.What i would like to do is ADD a CHECKBOX next to each Date Field.And make it work like this.
1. let them autopopulate as they are currently
2. if you end the call AFTER MIDNIGHT (the next day). CHECKING the box would automatically populate yesterdays date in each of the fields that has the check box CHECKED
