Queries :: Subtract Two Dates
Mar 6, 2014
I have two date fields. I want to subtract them to determine the number of days elapsed. The dates are in the following format: Dateserial (Year, Month, Day). When I subtract them I get 7670 as the result when the number should be 365 if they are a year apart. How can I subtract the dates in a query?

I have two calculated columns in my query for example... table.num1 - table.num2 as "Col1" and table.num1 - table.num3 as "Col2"
I then want another column equal to:
Col1 - Col2
I know that I could say:
(table.num1 - table.num2) - (table.num1 - table.num3)
but I am wondering if there is an easy way to just take two calculated columns of the query to use in the calculation of another column.
doing something like:
Col3: Col1 - Col2
doesnt work because it doesnt see Col1 and Col2 within the tables.

ACCESS 2007
I've got a table in which some records are associated with a number (numeric field): 691, 692, 693 etc. My parameter query asks for the number I'm looking for (parameter) and should return all records associated with that number or with that number minus one.
Something like this:
enter parameter
find records
in which number = parameter
OR
in which number = (parameter - 1)
How can I do that?

My [datefield1] is formatted as dd/mm/yyyy
I wish to create a query that produces a return of the previous month and year. i.e.
25/03/2015 (though a query formula) becomes Feb-15
01/01/2000 would return DEC-99
etc
This way I can then link all of my February data (formatted "mmm-yy" to my [datefield1]
I have tried subtracting day and formatting to months and subtracting then the value of a month but it all becomes too complicated because of the different days in the months and Jan to Dec and year as well.

I have the following source data:
Code:
Item Revision Start End
332 B 9/2/11 9/15/11
332 C 9/21/11 9/22/11
332 E 11/2/12 11/29/12
2A9 A 1/13/13 1/14/13
2A9 C 1/16/13 1/18/13
I'm trying to make a select query to provide the following output (RevisionStart-PreviousRevisionEnd):
Code:
Item Revision Span
332 C 6
332 E 407
2A9 C 2
I've struck out with union queries and aggregating/sorting letters and don't know where else to look. Is there a specific name for this type of operation anyway?

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 have two tables with dates. Between (!) every two following dates in table1, I want to know the number of dates in table2. How do I write an SQL query for this? The tables I have are up to a few hundred records in table 1 and a few thousand records in table2. So to prevent that this takes hours I need a fast query.
To explain the query I need, for example:
table1
01/01/2014
15/01/2014
17/01/2014
30/01/2014
table2
01/01/2014
02/01/2014
05/01/2014
17/01/2014
18/01/2014
20/01/2014
21/01/2014
25/01/2014
So the answer of the query would be 2,0,4.
Explanation:
Between 01/01/2014 and 15/01/2014 in table 1 there are 2 dates in table2 (01/01/2014 is not included between the dates)
Between 15/01/2014 and 17/01/2014 in table 1 there are 0 dates in table 2
Between 17/01/2014 and 30/01/2014 in table 1 there are 4 dates in table 2

I have a database to keep track of time spent on development work. The database uses mainly two tables: Estimates and Status.
The Estimates table holds a static number for each item to be worked on. We generally subtract this number from the total number of hours in Status spent on each of the items. In queries, to calculate the overall delta, we subtract the Estimate from the overall Status for each item.
However, we would like to create a report that gives us a running total for each item. So, if we have 100 hrs in the Estimate table for Item A and 5 hrs for item B, then the report would ideally show something like this (delta between Status table and static value in Estimate table):
Code:
Item | Resource Name | Estimate | Actual | Delta
--------------------------------------------------------
A John Doe 100 10 -90
A Jane Doe 90 5 -85
A John Appleseed 85 5 -80
B John Doe 5 10 5
B Jane Doe -5 5 10
This is so that we can see how our actual hours spent working on a task line up to our estimates. So, if we are under estimating our work, we can easily see this.
In Excel, this is of course no issue, but it becomes an issue when trying to write a query in Access to report this information.
As I said, we can do the overall numbers, just not the line item numbers.

I have written a large number of queries to gather data for a quarterly monitoring form. How do I replace the dates to update them for next quarter.For example I have written a query which counts the number of new members who started in the period 01/04/2013 to 31/07/2013. How can I change this (and the other 200 queries) without opening them all individually and manually altering it. Is there an Access equivalent of Word's Find and Replace?By the way I am using Access 2000.

Hi, I hope someone can help me out with this problem:
I have 2 tables with identical stucture, and no unique ID number.
Both had identical data, and the databse was then copied onto 2 laptops. Now further data was added onto each.
I want to now merge the three databses (ie original one, and 2 laptops) into 1, without creating duplicates- so I need to identify which are the new fields added to the databases. I figured that by somehow subtracting the original table from the new ones, i would be left with the new data, but dont know how to do this. Or is their another way?

:confused: Need help building a query that will subtract the previous value from the next value at each change in date
Date Tier 1

1/20/2006 4.27

If there is such an animal...
My employer uses a third party employee tracking system and I do back end work to massage the raw data for ad hoc reports using tables created by this third party software.
Is there a simple means to have a query compare Table A and Table B where Table A is a list of all jobs in a company - both filled and vacant - and Table B is a list of all employees in the company? The table containing jobs data has no field designating whether a job is filled or not. The only way to determine vacancies is to compare the two tables and select only those job numbers where there is no matching employee.
So, using examples from an earlier question - one that KeithG answered perfectly - let me see if I can demonstrate what I'm trying to do...
The Jobs table has two fields; JobNum and JobDesc.
The Employee table has three fields; EmpNum, EmpName, JobNum.
Here's Table A, Jobs;
100, Boss
105, Aide
200, Manager
201, Worker
202, Worker
Here's Table B, Employees;
111, Montgomery Burns, 100
112, Waylon Smithers, 105
121, Homer Simpson, 201
122, Lenny Leonard, 202
Jobnum is the link between the two tables in the query and the query's fields are;
JobNum and JobDesc
The result I need is;
200, Manager
The only vacant job.
So, how do I do a subtract query, if that's even a proper term? How do I have a result that is all of Table A that does not have a match in Table B?
Thanx!

I have a report based on a query where I get results sorted by month after i have chosen 'from date' and 'to date' in the beginning. I also want a set number for each month to be subtracted from the total sum, and then added to the next month (even if it is a negative number). Ex. Total in january is 100, then it is supposed to subtract 50 from that number, report the result of 50 in one own field at the end of january, then send this to february where the total sum is ex. 200, then the total sum for february is supposed to be 250, and then again a different number, like 60 is automaticly subtracted from the total sum and displayed in one field as the result 190. And so on.. Does anyone know if this is possible, and how? I am a noob, both in access and in the english language :P

(hard being a rookie)
On my Form, I want to have a query look at one specific field for a number (1). If the number is found then I would like to have the query do basic subtraction on two other fields. (one from each table)
What I have so far is one unbound text box with the following,
=IIf(tblDaStrategy!DaNumber=1,(tblDaStrategy!DaTar get-tblDaReport!DaActual1))
Simply put, if one field has the number one in it, then take the other two fields and subtract (ex. 100-75) to display 25.
It's not working. I keep getting the #Name?
Update: I think I got it. I went back to square one and made a master query that contains the data from both tables. Then I bound one of the forms to the query. I updated my IIF statement and poof. It seems to be working. Now, where's the Asprin and my pillow?
Update 2: Bummer, now my magical 25 is in place but now my form is locked tight. Guess I need to consider abandoning this concept and simply producing a report with the 25 on it. Unless someone out there has a better idea.

Hi,
Working on a query, what I have is a user will select a date on a form and hit submit.
I need the query that it runs, to pull all data -1 day from what they select.
So if they select 10/31 on the form, it needs to pull everything for 10/30 only.
I have this in my query now,
[Forms]![frm_change_report]![txt_Date]
Which pulls the data for the date they selected, but not sure how to subtract a day.

I'm sure this is simple but my brain is mushy this morning!
I have two datetime fields ADMISSION and DISCHARGE with values such as 03/02/2008 15:00. How do I convert these to dates only? I don't want to just *format* them as dates, which I can do. In this example I would want to convert that date to 03/02/2008 (or 03/02/2008 00:00)
It's an idiosyncrasy of the way the NHS calculates hospital length of stay. Our previous IT system had dates and times in separate fields so I could just ignore the time field and work out length of stay based on dates only. However, our new system returns a combined datetime.
Patient A 03/02/2008 00:15 to 03/02/2008 23:45 = 0 days
but
Patient B 03/02/2008 23:45 to 04/02/2008 00:15 = 1 day
Basically, you count a day if there's a date change, even if that was only half an hour (or even a few minutes) either side of midnight, but you DON'T count a day if there was no date change, even if that was almost 24 hours.
So formatting them as dd/mm/yyyy wont work ,as I will still have partial days when I subtract one from the other and INT([DISCHARGE]-[ADMISSION]) wont always work either as it would calculate 0 for patient B.
Help!

In my database I have a list of organizations with a certain goal. If that organization can not hit that goal we have to "reallocate" the left over goal to another organization. As it stands now I have the following fields, Goal (which should stay stagnant), change (to either subtract from one organization and add to another) and New. What I would like to do is have a way to have a way to calculate if there is a change to maybe have a drop drown that when the change is subtracted I can add that to "new" of another organization.
