Calculated Field

Feb 22, 2007

This seems a daft question but I have searched the forums and can't find an answer so I hope someone can help me.

I have a table: Register(RegID, Pupil, Activity, Duration, Preparation)

I have a query that I want to calculate the total hours the pupil has spent on activities.

The Duration and Preparation fileds are held as number of minutes so for a 1 hour event the number 60 is held.

I have a query with 4 fields:
Pupil
SumofDuration
SumofPreparation
TotalHours = ([SumofDuration]+[SumofPreparation])60

The problem I have is that TotalHours is calculating as an whole number.
e.g. I have a Record
Pupil = 701
SumofDuration = 270
SumofPreparation = 0
TotalHours = 4

But I want TotalHours = 4.5

I have set the Duration and Preparation field sizes to Decimal and Format to General Number.

I don't know what else to try.

Basing A Calculated Field On Another Calculated Field

Apr 12, 2006

My query contains two calculated fields [TaxSavings1] and [TaxSavings2], which are based on some currency and number-type fields in one of my underlying tables.

I just created another field in my query which looks like: [TaxSavings1]+[TaxSavings2]. Instead of adding the two fields, it actually lumps the two numbers together. For example, if [TaxSavings1] =135 and [TaxSavings2]=30.25, it will give me: 13530.25. I need it just to simply add, i.e. answer of 165.25.

Does anyone know how to correct this? Thanks in advance.

:confused:

Tables :: How To Make Calculated Field Based On Field In Another Table

Table1 contain Two fields (3Months) and (6Months)

Table2 contain Two fields (3Months) and (6Months)

the table 2 is the source of a form that will let the user change the numbers. table 1 should change Date1 and Date2 Fields based on the two fields (3months) and (6months) if i want to make a lookup wizard it should be changed manually and if i make a calculated field i can't find other tables in the expression builder

Queries :: Calculated Field To Display Value Of One Field Based On Another

Jul 23, 2015

I have a query with a Date field for EndDate (the dates for end-of-week, Fridays in our case) and another field for Sales (number of sales, not dollars).I want to add 4 calculated fields that represent weeks and have the Sales appear in the correct column (field) for that date.So I will have columns for 10 July 15, 17 July 15, 24 July 15 and 31 July 15 and I want the Sales for each record to land in the correct date column, based on the EndDate column. (The 4 fields is just for the sake of the example, I will actually be having dozens of these calculated date fields).I tried to do it by setting up the 4 calculated fields like:

10Jul15: Sales
and then adding Criteria like:
EndDate = #10/07/2015#
It doesnt work.

Calculated Field

Feb 9, 2006

Hi,
I have a calculated field in a query that concatinates an order number prefix and the part number to give the order number:
OrderNum: [OrderPrefix] & [PartNum]

There are 2 tables:
tblPartsList
PartNum
PartDesc

tblPartsListCategories
OrderPrefix
OrderNumCategory

This works fine except for one of the categories. For the third category there are no entries in the tblPartsList - because they are miscellaneous.

How do I change the calculation so that it works as above where there are corresponding Part numbers in tblPartsList and otherwise gives me the order number and any 2 digits e.g. something like [OrderPrefix]*

Having been trying to do this for ages but having trouble with syntax.

Hello Guys,

I am trying to do the following in a form.
1) (Travel hours + work hours) * dollarperhr to get the "Total" bill to a customer.

2) The results will be put in a field "TotalDollars" that is a part of a table.

Please help.

I tried to put an event (on change) on the "dollarperhr" box so that after entering the values in "travel hours" + "Work hours" * "dollarperhr", the calculation will be done to populate "TotalDollars", but it didn't work.

Calculated Field

Dec 21, 2004

Hi here is my problem

I have a table named= Commun tasks
which has 3 fields= [Commun tasks],[Quantity] and [Unit Cost]

I created from that table a form who shows these 3 fields. I also created in that form a calculated field (named Total) who shows the Total. I simply wrote
in the control source =[Unit Cost]*[Quantity]

I have another table (Project Information) who has 3 fields=[Prior total],[New Total],[cost addition]

What I need to do is each time the [Quantity] or the [Unit Cost] are changed, I need to show the [New total]. But also i need to show the [Prior total] which is based on the [Quantity] and [Unit Cost] before the change. So i think i need to store the calculated field (Total) in a table, but I don't really know how to do that (I,m a newbie).

Ok let's simplify my question

How can I store in a table a value from a Calculated field? I know that we should not store calculated value but in my case I need to store them.

Thanks for help

How To Use Calculated Field In Next Field's Source

Nov 5, 2005

I am using a function to calculate the number of days in a quarter. I have the Control Source for field "A" set to
=CalcQtr1Days([AdminDate]). I am calling CalcQtr1Days and passing the AdminDate. It calculates the number of days I'm looking for and returns that number in my field. Then, I want to use that number, along with DaysAbsent, to calculate DaysPresent. So, in field "B" Control Source, I have =CalcQtr1Days - DaysAbsent.
This gives me #Name? in field "B". I've also tried =DaysPresent = CalcQtr1Days - DaysAbsent but doesn't work either. What is the syntax for using the value calculated in field "A" in my calculation for field "B"?

Thanks,
Rod

Calculated Field From A Combo Box

Mar 9, 2006

I'm trying to get some equations to work for a database involving ski lifts.If I can get it to work right it should give me the resulting tension on the lift.
I have a two combo boxes that contains two values, counterweight and Hydralic, the other one has the values extends cylinder and retracts cylinder.

if counterweight is selected it should calulate the value with the equation
([L/bore]*[w/Rod]*[D/quan]*145+[additionalweight])/[counterweightparts]

If Hydralic and extends cylinder is selected it should calculate it with
(3.14*[L/bore]^2)/(4*[D/quan]*[additionalweight])

If Hydralic and retracts cylinder is selected it should calculate it with
(3.14*([L/bore]^2-[W/Rod]^2))/(4*[D/quan]*[additionalweight])

I'm trying to get this to work using IIF statements in a query but I can't seem to get it right.

I hope I was clear enough in my explanation. If any body know how to get this to work or nows a better way of going about it please help, Thanks.

Summing A Calculated Field

Jan 17, 2005

Hi,

I want to sum a calculated field on one of my forms. The field is calculated by multiplying the cost of a good by its quantity. So far I have been unable to sum it. Does anyone know how I can do this?

Here is a link to what the field is related to just so you people know what I am talking about: Project (http://www.access-programmers.co.uk/forums/showthread.php?t=78815&page=1) ...basically I have fixed all the problems mention in that thread. All that remains is this field. I will attach my project in case that helps. (the calculated field is in the Treatment Form) Thanks in advance :)

Help Please Calculated Field In Table Or Other?

May 23, 2005

Im not sure the best way to go about this and would be most grateful if I could be pointed in the right direction.

If I had a table called tblEmployee and a field within it called "PayRate" and another table called tblHours with a field in it called "LabourCost" and a field called "Hours". What is the best way to hold the "LabourCost" value so it doesnt get affected if someones "Payrate" is changed.

I expect I have asked this all incorrectly and I really do apologise.

Many thanks in anticipation... :)

When To Save A Calculated Field

Jan 12, 2006

Hello everyone,
I have been trying to calculate the number of working days a person has off sick between two dates.I was aware of how to calculate the difference between two dates using datediff, this was not quite hat i needed.
after much experimentation and a little searching I came across this site that has I would recommend to other beginners to use as a query and a module.

http://www.mvps.org/access/datetime/date0006.htm

I have a calculated field that uses this function to work out the number of days, My question is, Is it worth me saving this calculated field physically in my table instead of in the query?

The reason for this is that im only with company for limited time and others will be building reports in the future and would prob prefer to build reports on tables rather than queries. If so, how can I go about setting the field value to that of the query result?
