Ok, I know it's simple but...
subtracting field B from field A.
Field A has data in all records, field B only some. The 'only some' I get a result but the ones that have nothing in B I get nothing even though A has data.
Both are currency and default is 0.
How do I take nothing from something and get nothing you ask ?
I have a calc'd percentage field in my query. This is a multi user app and the problem is that is can (and does often) happen that the numerator information for my calc gets entered before the denominator data and therefore the calc'd field shows and as an error.
I attempted to use a simple IIF statement to input a message rater than the error code but now the field will not format to Percent. It worked, I got the message to display and it calc'd the records that had data, it just will not display in percent format. It does let me set the format to percent, it just doesn't display and does not allow the decimal places to be set.
This was the line:
CalcPercent:[Numerator]/[Denominator]
This is the new line:
NewCalcPercent:IIf([Denominator] = 0, "Message", [Numerator]/[ Denominator])
I've tried to search for an answer and I'm sure it is going to be something simple that I've overlooked.
Any thoughts?:confused:
I want to create a calculated field that If the employment type is FT Hourly or PT Hourly it will have a pop up screen for the Hourly Wage to be entered. If those criterion are not met it nulls the Hourly Wage field.
View 1 Replies View RelatedI am working with Access 2010, on vista. What I have is a query made up of two tables, one product the other inventory. (see below) query.jpg
In the product table i have a field called "minimum reorder level". In the inventory table i have two fields one called "number in stock" and "number on order". What i want to happen is "number on order" to be filtered by the result, if the "number in stock", is less than "minimum reorder level", if it is, have the result placed in the "number on order" field. EG. if the "number in stock" = 2 and the "minimum reorder level" = 5 then 3 would be placed in the field "number on order" and only the second record from the query would be visible (see below) Query result.jpg The result of this would mean that the field "number on order" would be populated with the result and the and query would also use this to filter the record.
I have a list of all previous employers for a job applicant. I can enter up to 10 but I only want the boxes to show if there is a previous position for that box. So, if there are 3 previous positions, I want to see 3 lines. If there are 10, I want to see 10. I have fields [Company_1]. [Company_2], etc. I only want company 2 to show if the person has 2 previous positions entered into the form.

I have a Qry field:
TotalUsage: Val((Round(Nz([UomUsage])/DSum("Nz([UomUsage])","[tblDetail]",),4)*100))
the problem is that the DSUM needs to sum up all the like records using the same SubID. I need some extra code in the divisor part. EG
subID uomUsage TotalUsage
33 10 100
33 40 100
33 50 100
34 43 100
34 57 100
the dsum needs to use SubID in order to sum correcly EG on SubID 33 as 100 uomUsage.
SubID is a Number field, Long integer.
I am presently getting wrong info. the formula above Dsum is summing as 200 since i eroneously don't have Subid in the Qry calc.
How can i fix? Thanks

Hi,
I've searched hours on the forum but with no luck. If there's anyone out there who can help me would be very much appreciated.
The calculation in Excel is very simple but I am unable to replicate in Access. Please don't confuse this with FIFO calculation as it is purely Weighted Average Cost method based on Buy unit prices i.e Sale unit prices are not required as it will sell at the Average Cost of the Buys upto the point of Sale.
i.e.
Buy 100 @2 = 200
Buy 100 @3 = 300
Total 200@ 2.50 =500
Sell 100 leftover will be
Total 100 @ 2.50
I am attaching an Excel S/sheet which shows the Calculation of Stock ABC and the Average Prices (which is what I am trying to achieve). I have also attached an Access Dbase with same details but without any calcs as whatever I have done I am unable to achieve my result.
Any help will be much appreciated.
Thanks
This is the second edited section:
I got the update query to work properly. Is this the best way to solve my problem?
This is the original edited section:
For the problem below would it be possible to use an update query to update the table?
Criteria for the termination_date field would be "is not null"
payment_to_date Update to: field would equal DateDiff("m",[payment_start_date],Now())*[monthly_payment]
Is it possible to use other fields in the table as part of the UpdateTo: calculation? I get an error when I try this.
This is the original question:
I have a field in a table called payment_to_date that I want to always be populated with the current total of how much a customer has paid to date based on their monthly payment rate. I have a form for data entry into this table but once their account info is entered the first time their won't be any changes to the account unless they terminate the service so calculating from an event procedure on the form doesn't make sense to me (I am new at this).
I entered the following in a text box control source on the form and it works but the textbox is not bound to the table so it's not the right way to do it.
=IIf([termination_date] Is Null,(DateDiff("m",[payment_start_date],Now())*[txtpayment]),(DateDiff("m",[payment_start_date],[termination_date])*[txtpayment]))
The calculation from above is basically:
If there is no termination date then the payment to date = the number of months between todays date and the date payment was started multiplied by the monthly pay rate.
Can anyone tell me how to keep the information in the table current for the payment_to_date field?
Any help is appreciated.

Hi,
I have a fairly simple database that looks like the attached. It is the beginnings of a school database. Unfortunately, the MS template doesn't quite do it.
We have around 700 pupils in 5 year groups. Each year's intake is assigned the year of that intake (e.g. 2002, 2003 etc).
The youngest pupils are in Year 7 whilst the oldest are in year 11.
Each Class is assigned based on the intake year but given the name of the schooling year - (e.g. year 7, year 8 etc). And there are 6 classes per year - hence names 7.1, 7.2, 7.3 etc.
My "Students and Classes" table should combine both the classes and pupils. However, I want to be able to firstly select the class to put the pupil into (and hence infer the induction year), then just show in the next filed only
the pupils that belong to that induction year and hence go into the selected class.
However I design my lookup or query, I can't seem to figure out how to do this, or if this can even be done.
Any help is much appreciated.

Hello everyone. I am very new to databases, may have bitten off more than I can chew, but I was tried of working in 4 different spreadsheets and decided to pull them all into a database so that I could get what I wanted when I wanted. Here is what I need to be able to do: In a table I have 3 different industries entered 5 different times. They all cover a Monday to a Friday. Each day for each industry I record a reading from a meter. I make a calculation by subtracting Mondays number from Tuesadays, Tuesday from Wednesday, Wednesday from Thursday and Thursday from Friday. This calculation gives me how much water each industry used each day, over 24 hours. Doing this in a spreadsheet was simple. My table has the Industry name, date, previous day meter reading, present day reading. I want to have the calc show in my query. How do I set up this calculation. Any help would be greatly appreciated. Thank you. I attached a sample database that contains the table and query.:confused:

My head's swimming right now so the solution to this problem may be right under my nose and I'm just blind to it.
I have a table with events, represented by an ID number, and the date/time the events occured. Each event is also attatched to a particular mission number. Looks kinda like this:
Mission EventID Time
Each Mission has different events like liftoff and patient contact, and I need to find the time between events for each mission. I'm trying to calculate the Time from inital call to mission end, from dispatch to liftoff, ect.
Do I need to put these times into my mission table as columns, Time1, Time2, Time3... or can I leave them normalized and still run calculations on them? :confused:
Hi
I'm trying to finish a query that calculates the time worked in the AM and PM, adds them together, then takes that away from the standard working day.
I've done everything else, but when I take the hours worked away from the standard day it always ends up with a positive number, regardless if they haven't worked enough hours.
I've looked through the forums and everyone is talking modules, but thats over my head.
Thanks for looking, apprieciate the help.

How do I use fields in related tables to create a calc field? The wizard only shows me the current table's fields. Can I do create me desired field by manually creating the calculation and bypassing the wizard? Or is this another restriction of Access?
View 1 Replies View Related:confused: This seems like a very basic task, but I am confounded. I am trying to display results in a separate field from the concatination of 15 text fields in the same table. This result will eventually display as a string on a web (intranet) page.

Hello,
I need to create a query that will seach through a column and only return a result with product codes starting with A.
An example of a product code is AA0000034567.... however there is no realy consistancy. Some start with the AA and some don't. Some have 5 zeros before the numbers start others may only have 1, 2, 3, or 4 zeros before the number.... There are approx 76,000 product codes in total.
My end goal is to create a query to find all the records that have a product code starting with A so that I can eventually delete the AA00000 portion of the code and strip the number back to the point where the 34567 starts.
I figured that by separating out the product codes that start with AA would be a good start.
If any one has any suggestions please let me know.

Hi
I have a Form called Products. Each product is uniquely identified with a primary key called [ProductID].
Products contains a calculated field called [UnitsOnHand]. [UnitsOnHand] gets its values from a subform called ProductTransaction that exists within the Products Form.
ProductTransaction contains a field callled [Received] . At the moment [UnitsOnHand] will add up all the values it finds on the [Received] field to derive the [UnitsOnHand] value for that product at any particular time ie =Sum(nz([Received])) on [UnitsOnHand] .
I also have a Query AutoSell that outputs a value for each [ProductID].
How can I use these values for each [ProductID] generated by the Query to substract from the values on the [UnitsOnHand] calculated field on the Product form.

I've got these expressions in a query to extract parts of an mp3 file full path from a field and just let the name of the song.
exp: Mid([imported];[exp3]-[exp2];Len([imported]))
exp2: InStr([imported];"")-4
exp3: InStrRev([imported];"")
exp4: Left([exp];Len([exp])-4)
"exp4" is the clean name of the song.
Now how can I update my "song name" field (which is empty) to be same as "exp4" . Is it an update query? If so how can i do it?
