Subtract From One Record And Add To Another In Access
Jul 11, 2012
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.

I have a Motorhome which I want to check it's Fuel Economy, seems simple!
I record the odomiter readingwhen I fill up with petrol and the amount of petrol pumped in to fill tank and the cost
I have done it in Excel 97 but I would like to convert to an Access 97 Database.
The purpose is to open an Access Form, add a record with Three Fields, namely the odomiter reading, Amount of Fuel pumped into tank, and Cost.
I would then like Access to subtract the previous record's odomiter reading from the new odomiter reading to obtain the distance traveled since last fill and using this number and the other 2 fields I can calculate my fuel economy
I tried to attached the Excel (97) spreadsheet for your information but it was too large for this forum
The calculations are based on Australian Dollars, LPGas and Litres but it would make no differance if it were Gallons, US Dollars etc.
I would very much appriciate a note to tell me if anyone is able to assist me with this problem.
Thank You

Hi,
I am very new to access. I have designed a db for my employer, but I can't figure out how to subtract one field from another without having it subtract fom all others.
My employer is a counselor and wants to know how many units are left per client. There are several diffent services available per client. (88K, 86H, 81H, ect) For instance I tried to use a query, but when it was subtracting
(number of units)-(number of used) It subtracted from all the different service types.
Then I tried to do it on the form and all I get is #Name?
I can email you a copy of the database with a mock client if i'm not explaing myself enough. I know it's probably something very simple and I would appreciate any help. Also, if you know of any good books or websites where I can learn more I'd appreciate the info. I'm learning from Access 2002 Bible.

I have a 'tblStock' with fields 'ProductID', 'InitialStock', 'Buy', 'Sell' and 'UpdatedStock'. I also have a form 'StockUpdate' add values and also add new records to 'tblStock' .
If I have value [100] for IntialStock quantity, Buy [0] and sell [10], UpdatedStock will be [90] (that's done and fine!).
The problem is, I would like to make the UpdatedStock value [90] to be the NEW InitialStock, so that any BUY or SELL will keep updating the UpdatedStock and making it the NEW InitialStock for the next transactions and so on....

I am trying to create a P&L statement in access. I know what I want to come out at the end. I am just starting to play with access and having trouble getting what I want to come out of it.
On the sales side I have a query that gathers all the revenue sources and calculates a total for each date. I then use a second query to just take out the data I want for the P&L report. I created a sub-report that displays the data I want. I use the grouping and grand total features to get the total into the report footer. So far so good.
On the expense side I created a form of a query to manage the one to many relationship to capture the data for expenses (one purchase with many line items). I created a query based of this query to get the relevant data for my expense sub-report. I created the sub-report and got everything looking and calculating the way I want it to. I use the same grouping and grand total features to display the data in the report footer. Still good.
I created a new main parent report with the two sub-reports (sales & expenses) on it and even was able to pull the totals from the sub-reports into the main (so currently the subtotals of the two sub-reports are displayed twice). Now when I try to use the textboxes I used to pull the sub-report totals into the main report to perform additional calculations (sales - expenses) I get #error. I have tried different things and gotten ?name.
Control source for the two textbox controls on the main that display correctly, but don't let me do any further calculations.
=[rptP&LExpensesOverview]![AccessTotalsAmount]
=[rptP&LSalesOverview]![AccessTotalsTotal Sales]
To do the subtraction I have tried using the references above, as well as just using the names of the unbound text boxes in the report that bring the totals into the main report.
As a work around, I tried to build one query with all the data from sales and expenses, but can't "filter" based on date and get the data I want in the query results because the two sets of data are not necessarily related. I either get a long list of records, or no records (I am currently only playing with about 5 days of data).

Hi,
I have a query with two fields. One has the "MEASUREMENT" and the second one is the month containing the values. In the MEASUREMENTs I have gross revenues and discounts, how can I create a new MEASUREMENT (net revenue) that is calculated by subtracting the discounts from the gross revenue.

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
1/6/2006 4.22
1/13/2006 4.27
1/20/2006 4.27
1/27/2006 4.314
2/3/2006 4.314
for example, 4.22-4.27 = -0.05

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!

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.

Here's a sticky one? (maybe...) I have a number of aggregate totals from several queries all linked to the Input Query and all Nz'd as 0's
From the image enclosed the totaling text box (top right left) is calculating the value in the properties box. The value should be 3.52 + 5 - 8 = 0.52 the value showing is -4.475 (which is 3.52 - 8) so I see it's ignoring the 5 value but I can't see why.
The ACDays and ALDays values are both generated by the same module, but with different Leave types. and as I mentioned previously all Nz 0'd
Any thoughts appreciated, I'm baffled:confused:
