Calculate Field Using Sum Of Another Field

Apr 18, 2008

I want to create a calculated field in a select query.

Cost Per Call = Total Cost / Total Calls

The Total Cost is a fixed value that will be entered after the user is prompted.
The problem is that Total Calls is the sum of another field in the query called # Calls. Is it possible to calculate a field that uses a sum of another field in the query ?

Tables :: Calculate Value For A Field Based On Value Of Another Field - Statement

Dec 30, 2012

I'm trying to calculate a value for a field based on the value of another field, [Field1] has a value list of 28 choices I want [Field3] to take that value and multiply it by the value of [Field2]. I'm using an Iif statement and it sort of works. I looks like this:

IIf([Field1]=1 Or 2 Or 3 Or 4 Or 11 Or 12 Or 13 Or 21 Or 22 Or 28,[Field2]*0.06,IIf([Field1]=5 Or 6 Or 14 Or 15 Or 23 Or 24 Or 29,[Field2]*1.1,[Field2]*2.1))

I receive nor errors but it will only return the value of [Field2]*.06 no matter what is selected in [Field1].

I'm sure I'm missing something and there is probably an easier syntax to use, but I'm at a loss at the moment.

NOT EXCEL.

2) then i want that Total Incomer per class (In Table 2) = Enrollment * Income per enrollment so that value should be display on total incomer per class ....So if i change enrollment value ... then the total income per class value has to change ....

3) i want in table that my total income in all class should display in same table ( Table 2)

Having A Field Calculate Other Fields

Aug 15, 2007

I am trying to get one of my fields to calculate this expression which includes other fields:

If "Financing Type" = 1 or 2 THEN 20% * "Loan Amount" OR
If "Financing Type" = 3 or 4 THEN 100% * "Loan Amount" = 2,000,000.


I thought that this would work, but it only works in queries or reports.

=IIF([FinanceType]<3,[LoanAmount]*.2,[LoanAmount])

I would like this to work in the table.

Calculate Numbers From A Text Field?

Dec 27, 2006

Ok, this one has me stumped.

I have a several fields on my form that are list boxes that must have text as the properties so I can populate the lookup data with things like" Severe rating = 7 points" and "Moderate rating = 3 points". I have another similar field where the choices are "High probability = 9 points" and "Low probability = 2 points" etc. A third field needs to show the total points (product) of the choices from the first two fields, i.e. 9 points x 2 points = 18 points. Then,
a fourth field needs to display where the answer falls in a grid, i.e. 1-14 points = Low, 15-29 points = medium, 30-49 points = high, etc.

How do I apply the calculations on the field choices if the field properties have to be text instead of number?

Thanks,

Calculate # Of Occurrences Of String In A Field

Jun 25, 2007

Thought I'd be able to find out easily, but.. here I am...

How can I query the number of occurrences of a string in a field, e.g.:

if a name field has the text: Martin Lacoste

how can I get it to tell me there are two "a"s in the field?

I can use InStr to find one, and make a few more queries to find a few subsequent, but the data I need to search could have 30-40 occurrences of the desired text in a field.

Ideas?
Thanks!
Martin Lacoste

Calculate Numerical Data In A Text Field

Nov 29, 2004

is there any way I can make a field with a data type that calculates numbers in the field but also allows text to be entered into the field (e.g. N/A or No Score) The non-numerical data certainly wouldn't have to be calculated and could be filtered out when calculating averages and other numerical operations.

Thanks

Tables :: Auto-Calculate Field From Other Table Values

Aug 10, 2015

How to set up my tables as I'm just starting off with setting my database up.

I'm doing a simple database to track the purchase orders (PO) I am managing. Each PO has a PO Number and an Original Value. POs may have multiple amendments which would change the PO value. I would however like to keep the history of the PO original value and all different amendments.

So I created two tables:

tblPO:
ID
PO Number (Number)
PO Original Value (Currency)
PO Sum of Amendments (???????????)
PO Current Value (Calculated = PO Original - PO Sum of Amendments)

tblPOAmendments:
ID
PO (Lookup from tblPO)
PO Amended Value (Currency)
Amendment Date (Date/Time)
Amendment Desc (Text)

Now the two, million dollar questions are:
1.) Is this the right table structure to use.
2.) How do I go about calculating the Sum of Amendments field?

Queries :: Calculate Cumulative Values Stored In Field

Oct 7, 2013

I have several projects with different tasks for each. I have 3 fields [fkProjectsID], [TaskOrder] and [Duration] in a table for project tracking with that structure:

[fkProjectsID] [TaskOrder] [Duration]
1 /1 /5
1 /2 /8
1 /3 /15
1 /4 /6
2 /1 /8
2 /2 /30
2 /3 /25

I want to calculate cumulative values stored in [Duration] field (represent a number of days). I'm using the field [TaskOrder] to order different tasks within each project. With some testing, I was able to calculate cumulative [Duration] with 1 project using the DSum fucntion as following:

CumulDuration: DSum("[Duration]", "[tblProjectTracking]", "[TaskOrder]<=" & [TaskOrder])

I was having the sequence: 5, 13, 28, 34 for respectively Task 1,2,3,4. However, when I add a second project (and then a third...), I need to be able to filter based on [fkProjectsID] as well (i.e. a specific DSum by ProjectsID). I add this criteria but I get the sum of [Duration] on each row instead of the cumulative:

CumulDuration: DSum("[Duration]","[tblProjectTracking]","[TaskOrder]<=" & [TaskOrder] And "[fkProjectsID]=" & [fkProjectsID])
