Access Database Help With Dates
Jul 18, 2007
I have a database that includes dates in a table, and a form that I use to show items that are issued from a supply crib. The date is automatically input by the database. I have designed a report with all the data that I need. My problem is that I need to be able to print this report according to a specific start date and end date (which is usually a 7-day period), and I can't seem to get this accomplished. Could someone please guide me in the direction that I need to go? I have a query designed, but I don't know how to apply the query to my report. For example, upon opening my report, I need it to ask me for a start date and an end date, and print the report according to the dates that I input. At the present time, the report won't ask me for these dates. Any help would be greatly appreciated.

I have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date
So the first step (as I see it anyway) is to try to create a query which will give me each date between the two reference dates, in the hope that I can then JOIN that onto another query to perform the necessary calculation for each of the returned dates.
Is there a way to do this?
So basically, if for a particular record, the 'start' date is 01-Apr-2015 and the 'end' date is 09-Apr-2015, can I produce a dataset of 9 records as follows :01-Apr-2015
02-Apr-2015
03-Apr-2015
04-Apr-2015
05-Apr-2015
06-Apr-2015
07-Apr-2015
08-Apr-2015
09-Apr-2015
(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?

I would like to create an Access Database that calculate due date based on 2 tables, one with invoices and supplier details. The other one with Supplier name et payment terms.
Input:
Table with the following details:
- Supplier Name
- Invoice Date
- Currency
- Amount
Output:
Table same as input but with a column that shows for each record the Due Date. The due date would be calculated by adding payment terms in days from another table to the Invoice date.

I'm bringing an archived db into Access, with entry forms to continue on into the future for maintenance. In the past, some dates were recorded only to year (yyyy). Obviously, I won't continue that, but I need to integrate the old and new in a fashion that will sort. For instance, one form has a subform section based on a report to show the old entries, while below are unbounded text fields for making new entries (with a Save command button).
How to integrate partial old text dates with newly recorded dates.

I am trying to create a database to analyze expiration dates of multiple products.
Let me lay out what I am trying to accomplish.
I have 5 ambulances, each ambulance has the same quantity of medications on it. There are three separate locations medications are stored on each truck. Each month I need to be able to update expiration dates, query what medications will expire by a set date and where exactly they are located.
SO here is the structure as I see it.
Ambulance 1 contains, a drug drawer with approximately 30 different medications, a trauma bag with about 10 different medications, and a blood glucose kit with 2 different medications. Now some of medications are repeated in the different locations, but have different quantities. The medications will never all have the same expiration date, and medication 1 might have 8 vials, where medication 2 may have 4 vials. I would like my form to be dynamic based on the inventory level of the medications. That way if we decide to keep 10 vials instead of 8 the form will then require the 2 extra data points.
The tables I have created so far...
table 1 lists all the ambulances
table 2 lists medications in the drug drawer and the inventory level
table 3 lists medications in the trauma bag and the inventory level
table 4 lists medications in the blood glucose kit and the inventory level
I need to create a table to store my expiration dates for each of the locations in each of the ambulances.
I need to create a form to simplify the entry of the data into those tables and I want the form and table to be dynamic to the inventory level.

I am trying to create a database for a clinic, and am severely stuck on how to input appointment dates for individual patients.
I have been using the 'student' database from office.com as a template for how to save the dates (given that appointments and attendance are exactly the same!), however, even after following what has been set up in the 'student' template database, I can't seem to replicate it.
Every time I add multiple visit dates for a specific patient, these exact dates show up for every other patient in the database. I need to be able to add different dates for all the different patients.

I am developing a claim tracking database that tracks dates of events that occur in the course of processing a claim; such as, Loss Date, Report Date, Estimate Date, Payment Date, etc.
I currently have the following tables set up:
tblClaim
ClaimID
ClaimNumber
tblEvents
EventID
EventName
tblClaimEvents
ClaimEventID
fkClaimID
fkEventID
EventDate
With this table structure there is a many-to-many relationship between Claims and Events, but, there will only be one of each event per claim. Is there a better way to set up the tables to enforce a 1-to-1 relationship?
I was planning on creating a form for the Claim table with a subform for the Events joined on ClaimID and fkClaimID, but that would allow users to create more than one set of Events per claim, if that makes sense.

I am creating a database that tracks current projects for my team at work.
Some projects are only due once (e.g., mailed brochures due on 1/1/14) and some are due at scheduled intervals (e.g., status report due monthly, quarterly, etc.)
Ultimately, I'm hoping that my end result will allow us to click on a form and look at what everybody has due that day, in the next 7 days, and so forth.

Can anyone tell me how to generate a query that shows the results for the 'Last 12 Months" based on a Date field?

I'd like to create a recordset from an Access database that reads the 'Date' field and only selects dates in the past. That way I can enter info ahead of time, give it a date of a week from now, and know it won't show up on my pages until next week.
It should be simple, but what I have isn't working. Here is my code:
Query = "SELECT Id, Date, Info FROM OldNews WHERE DateDiff('d', Date, date()) <= 365 ORDER BY Date DESC"
It lists all the records that are 365 days old, but it still shows any future dates as well.
Does anyone have a better idea?
Thanks!

I have is rounding down dates in Access. I seem to be having trouble with the equation I built below:
Months Remaining: IIf(Date()<[Anniversary],Round(DateDiff("m",Date(),[Anniversary],Round(DateDiff("m",Date(),[Anniversary]+12)))))
My goal with this formula is to produce a number of months remaining (rounding down) by subtracting today's date from the anniversary date. The Round function I put in there seems to not work as the result is the same when I remove it.
Another thing I am also trying to accomplish is having the date pushed forward if todays date is greater than the anniversary date. In this instance, I tried adding 12 months to get it back on track. So say the anniversary date is july 4th 2015 and todays date is aug 4th 2015, well thats gonna show negative 1 but if I add 12 it should bring it to 11 months remaining -which would make sense because the anniversary month and day is fixed but the years just get pushed.

Hi,
I have developed a small hotel booking system which inserts records into a reservations table. The table looks like this:
[ReservationNr][StartDate][EndDate][RoomNr]
I am now trying to add a constraint which prevents a room from beeing booked twice on the same day, hence the time period defined by StartDate and EndDate in a record must not overlap with another record.
Is Access capable of adding such a constraint?
It was easy to add a constraint that prevents a booking where the StartDate is before the EndDate, but this one needs to reference already existing records.
Any help would be much appreciated.
Thanks

I have searched the forum for this answer but no luck. :(
I'm trying to calculate the amount of WORKING time between two dates in an Access database. At the moment i am just subtracting one date from another but this gives me all of the time in between including weekends and evenings.
I need this time to be calculated in hours.
In Excel i know there is a NETWORKINGDAYS function which does something similar but with days rather than hours.
At least if i could get the working days i could then convert it into hours.
Please help!

Any way to have a form with Dates as column headers to update a table where the dates are stored in rows???
The table set up is like this:
tblOpHdr
DiaryID (PK) - OpDate (Date)
tblOpDetail
DiaryID (FK) - CostCode - MachineNumber - MachineHours - etc
I'm just wondering if there's any way I can do this with a datasheet or a crosstab type setup?
It's Access 2010.

Hi, I am a longtime Excel user, and am now migrating some work to Access.
I have 2 fields dealing with dates in the format mm/dd/yyyy hh:mm, OPEN and CLOSE
I'd like to get the difference between the two in hours, but I have no idea how or where to do this in Access. I'm assuming it is put into the queries, but it would be easier if I could just put it in the table.
Here is an example
1/1/2008 1:00 1/2/2008 2:00
I want the result to be "25"
Thanks in advance!

Hi everyone
I'm a very very new access user so many apologies in advance for when I have no idea what I"m talking about.
I'm working on creating a report that will display multiple expiration dates. Currently I have an employee database, not created by me, that has all of our employees professional licenses listed.
Prof license, auto license, liability, etc.
I want to create a report that will tell me what has already expired or will expire in the next 30 days.
I did use this
Between DateAdd("d",-30,Date()) and Date() and it is bringing back info up to 2009. which isn't what I need. I'm sure I'm doing something wrong here.
I want anything that has expired regardless of the date from today, before today, and 30 days from today but I don't care about anything more than 30 days from today's date.
I noticed that when I looked at the existing database that the fields are set as text fields. I tried to change them to dates and it gave me a "deleting 106" records error message. Yikes!
Any help would be appreciated. I don't really understand expressions and I don't understand if I'm supposed to put the actual date in parentheses or what. Please pardon my ignorance.
Many many thanks.

I have a retort that I want to use an option button to filter the report is a specific date is 48 hours before the current time. I'm not having any luck. Below is the code I have been playing with, but no go.
Private Sub NoMove_Click()
Select Case Me.NoMove.VALUE
Case 1
Me.Filter = "CLM = 'Now() - 48'"
Me.FilterOn = True
End Select
If Me.Filter = "" Then
MsgBox "The filter returned Null"
Else
End If
End Sub

Is it possible to create a query to select all dates from a given reference date? I don't mean all dates in a table - I mean all dates generally?
(The idea being to fill the first field in the resultant dataset with the list of dates, then run subqueries off that to fill the remaining calculated fields)
I'm currently using a date field in one of my tables to populate this first field (the full SQL is in a separate thread here)
But that was just a convenient way of getting a list of dates; the dates in that table don't actually have any significance to the resulting dataset (other than they should roughly overlap with the dates I'm looking for)
The flaw in that method is that the table from which I get those dates can only ever have dates up to and including yesterday. I also need to get today's date in there (and calculate the subqueries based on that date as well).
It's also possible - although unlikely - that there could be random dates missing from that table as well - in which case I need to plug those gaps and calculate my fields for those missing dates as well.
For clarity; that first field (AsOfDate) should contain every weekday from the earliest date in that table (i.e. Min([tblBalances].[BalanceDate]) up to and including today. It doesn't matter if any of the dates inbetween are missing from tblBalances as the subqueries will just return zeroes for those dates (which is exactly what I want to see).

I'm new to Access and VBA, for the record. What I need to do is copy a SQL database (table structures and records) and save it as a local Access database, so that the user can query and make any changes on the local file without editting the SQL database.
Looking around, it seems like the best option would be to use the TransferDatabase method with the acImport option. Does this sound reasonable, or can someone with more experience suggest a better way to go about it? Thanks.

Hiya-
I have a database with 5000 entries, corresponding to about 10 entries for about 500 people. Each of the entries is dated, and I need to calculate the time intervals between each person's sequential entries in the table.
One way of doing this is to create another column that contains the date of the previous entry. I can then use DateDiff to subtract one date from the other and give me the difference in days.
This approach falls down if I then work with only a subset of the entries - I would have to re-enter the previous entry dates as the time intervals would have changed.
What I really need is a way of subtracting the date from the date in the cell directly above it. Will Access let me do this, or is there a better way?
Many thanks, Jules.
