Prevent Duplicate Records For Calculated Field
May 3, 2013I have a table for storing vehicles. The table contains the following fields:
VehicleID
Make
Model
Trim
Build Date Begin
Build Date End
Vehicle Name - a concatenation of 'Make' 'Model' 'Trim' 'Build Date Begin' and 'Build Date End'
The 'Vehicle ID' is the primary key, the rest of the fields can't be indexed with no duplicates. Is there a way of preventing one from saving a duplicate VehicleName on the table since it is a calculated field.
Having A Records Calculated Field Get Info From Previous Record
Jan 20, 2007I have a table (tblStats). The user enters his current weight in a field named Wt. There are 2 other fields in the table named WkLoss and TTDLoss. These two fields are intended to be calculated. What I am trying to do is when the user enters his current weekly weight figure into the Wt field, I want the field WkLoss to get the user's weight from the previous record and place the difference in the field WkLoss. Also I would like to keep a total to date in the TTDLoss field.
So far this has been my attempt.
Code:Public Sub setWeight()Dim rs As DAO.RecordsetDim Startval As DoubleStartval = 190Set rs = CurrentDb.OpenRecordset("tblStats")'Select records to be updatedSet rs = CurrentDb.OpenRecordset _("SELECT * FROM tblStats ") rs.MoveFirst Do rs.Edit'field to update rs.Fields("WkLoss") = Startval rs.Update rs.MoveNext'increment step value Startval = WkLoss - Wt Loop Until rs.EOF rs.Close Set rs = Nothing End Sub
All I get is the value 190 placed in the first record and all zeros in the subsequent records. Also I don't have a clue as to how to get the Total To Date field to calculate.
Any help would be appreciated
Thanks for your time.
Queries :: Put Sum Of All Records In Calculated Field And Divide It By Predefined Value
Feb 6, 2014I want to take the sum of all records 'cost' i.e.
record 1 - 2
record 2 - 4
record 3 - 3
I want to take the sum and put it in a calculated field and use it to divide it by a predefined value 'no of responses.'
So I make the field in the query -> Calcfield: (Sum([cost])/[responses])
I am pretty new to this and i don't understand why this won't work? Is it something to do with the row Group by (total.)
Queries :: Calculated Field Is Blank For Records With Even Primary Key
Jun 17, 2013I have a calculated field in a query. The field name is TotatPt (this is to calculate the total points students have earned during the term). The expression is as follows:
Code:
TotalPt: [Att1Pt]+[Att2Pt]+[Att3Pt]+[Att4Pt]+[Att5Pt]+[Att6Pt]+[Att7Pt]+[Att8Pt]+[Att9Pt]+[Att10Pt]+[Att11Pt]+[Att12Pt]+[Att13Pt]+[Att14Pt]+[Att15Pt]+[Att16Pt]+[Att17Pt]+[Att18Pt]+[Att19Pt]+[Att20Pt]+[Att21Pt]+[Quiz1Pt]+[Quiz2Pt]+[Quiz3Pt]+[Quiz4Pt]+[Quiz5Pt]+[Quiz6Pt]+[Quiz7Pt]+[Quiz8Pt]+[Quiz9Pt]+[Quiz10Pt]+[MidtermWritPt]+[FinalWritPt]+[Proc1Pt]+[Proc2Pt]+[Proc3Pt]+[Proc4Pt]+[Proc5Pt]+[Proc6Pt]+[Proc7Pt]+[Proc8Pt]+[Proc9Pt]+[Proc10Pt]+[Proc11Pt]+[Proc12Pt]+[Proc13Pt]+[Proc14Pt]+[ProcPracPt]
I think this should be no complicated expression (though a bit long) and should just add the fields together. But what I get is that the calculated field appears as expected for records with an odd primary key (1, 3, 5, 7, ...) and turns out blank for records with an even primary key (2, 4, 6, 8, ...)!
I've attached a screenshot.
Basing A Calculated Field On Another Calculated Field
Apr 12, 2006My 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.

Calculated Records
Mar 14, 2006Hi
I have read a number of these threads now where it says you should not generate new records based on calculated fields. So can some one help with my following problem.
I am creating a customer/contract database where when an order is created, a record set is generated to store dates for invoice periods. I have done this by using the start date of the contract and then adding onto this a value of x days that updates a table giving y records based until the end date of the contract.
Is this the best way to do this or can some one tell me a better way.
Thanks

3 Queries, Need Records From Both Even When The Calculated Value = 0
Feb 19, 2008(Phone usage report) I have 3 queries, Query 1 counts number of calls in for a phone extension. Query 2 Counts the number of calls out (dialed calls). The information is keyed on the phone extension. Query 3 runs the first 2 queries (By date via parameter). Each query is keyed on Extension, I only want to see the number of calls in and out for each extension. Problem, when a phone extension being counted has no calls (In or Out), it leaves the phone extension out of the report. I want to see all the phone extensions info regardless of the count (if it = 0). Does anyone know a way around this? Thanks in advance for your help.;)

Jul 23, 2015I 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.

General :: Calculated Fields - Reading And Modifying Records
Aug 2, 2012I am new to Access and this is likely a very elementary question. I recently created a database to track status of projects including progress and funding. The table contains several fields that record various aspects of funding. These fields are added (very simply) and create a calculated field that is a summation of those fields. The table currently contains approx 60 records. The calculated field functions for 2 or 3 records and will not calculate further. I have tried this in a form as well as a query. The form will change the same number, 2 or 3 records. When the query is run the result shows only the 2 or 3 records. What I am doing that is only reading and modifying those records?
View 3 Replies View RelatedReports :: Sort Records By A Calculated Percentage Using Text Box Values
Jan 27, 2015So I have a report with the following text box controls:
[Surname] & ", " & [Firstname]
=Sum([Quarter1_A]) - Named "Quarter_Total"
=Sum([Quarter1_T]) - Named "Quarter_Target"
=Val([Quarter_Total])/Val([Quarter_Target]) - Named "%Target" (Percent Format)
The report is grouped by the expression '[Surname] & ", " & [Firstname]'.I am trying to sort the records by the %Target text box. I tried entering the expression into the sort function but it still sorts by the grouped expression. I also tried sorting by the name of the text box but got the same results. How can I sort by the desired control?
Calculated Field
Feb 9, 2006Hi,
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.

Feb 22, 2007This 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.
