Storing Calculated Fields - Example Post For SBaxter
Aug 15, 2004
Here is an example of what I was talking about re: private message and storing calculated fields. Any help is much appreciated.
Also I received your email in regards to a sample secure database but I am getting a "Memory could not be read" error when I try to open it. Does this have anything to do with how it has been converted to 97 format or is it an error at my end? (I've been able to open other dbases from the forum).
Thanks,
Dearnne
PS Thanks also for your help with adding to option groups.

New to Access and learning the hard way. Im sure this is an easy one, but sure would appreciate the help. I am trying to sum a group of cells and display the total, which i have done. But I also want to store this total in my database. So my question is, how do i move my calculated total to my field that has the "record source" bound back to my field in the database? Hope that makes sense. Thanks in advance.

I know that it is bad form to store a calculated field in a table - normalization and all that - but I can see no other way around a need that I have.
I'm trying to make a database to store injury time for employees. If an employee is injured, he can do light work for a certain amount of time, but this light work need not be contiguous. But, the total time on light work must be known so as to see when it is used up.
For example:
Bob is injured on 4/1/06 and goes on light work on 4/2/06 until 4/5/06 (4 days). Bob is then taken off light work until 4/10/06 when he reinjures the same injury. This does not count as a new injury, because it is an aggravation of the old one. So, Bob goes back on light work on 4/10/06 until 4/15/06 (6 days).
So, I need to store Bob's total time on light work for this injury (10 days) so that I can keep a running total to check against the maximum for a single injury. All I can think of is to store the sum of days on light work as a field in Bob's injury record, but that means storing a calculated field in a table.
Am I missing an easy way to do this, or is there a method to do what I want that I am just not aware of?
Thanx for any help!

Hello All,
Probably trying to do the impossible.
Normally I would never (that’s a long time) have the results of a calculated field in a table, but I’m stumped.
Table1
TestID: Autonumber
Quantity: Number
Selected: Yes/No
Table2
SumID: Autonumber
TestID: Number, Foreign Key
Quantity Delivered: Number
Query1-Sum Query
Table2
TestID: Group
Quantity Delivered: Sum
Query2- Select Query
Record Sets
Query1 Table1
TestID-----------------------------------TestID
Quantity Deliverd Quantity
Select
Fields in Query2
TestID from Table1
Select from Table 1
Run Query
Can’t update “Select” field
So I’m thinking that I should create a 3rd query to update the summed Quantity Delivered into a new field in table 1. Which would in effect create a stored calculated field.

I have a score marking template for an internal audit. A criteria is either met, or it is not. All of these questions have Yes/No data type. each question has a weighting. I have written a VBA function to work out the total score by using a bunch of If statements.I need to store the final result in a table, by entering the answers (yes or no) into a form.

I know that it isn't usually best practise to store calculated fields in a table, but in my situation it is necessary, and I haven't really found a good answer for this after searching these and other forums.
Currently my database has one "Name" field (I didn't make it like this) which might look like this "Jonathan (John) Smith"
Now I also have reason to grab the name like this "Smith, John" for other purposes.
I've set up a form for inputting new people with separate fields for firstname, preferredname, and lastname. I have the calculated fields:
=[fname] & " (" & [pname] & ") " & [lname]
=[lname] & ", " & [pname]
(Later I will add in all the iif's for if there is no preferred name)
Upon finishing the form, the user hits Submit, and I would like to store the concatenated values into the table in their appropriate fields.
I can do this with a SQL INSERT INTO statement but I'd have to add all 25 or so fields from the form, and injecting user input directly into a SQL statement is not best practice either.

if i have formula in a text box can that calculation be stored in a table???
example
sales total
sales tax
grand total
where grand total = sales tax+sales total
if the control is bounded to a field in a table once the formula is entered doesnt it loose the connection with the field???
right now when i enter a formula in a control it will no longer store it in the table but it will only show the result in the actual form..???

Hi all, another beginner question here.
I have a table of records which is is basically temp storage, once I'm done inputing information, an append SQL statement is run to move the data to its permament table, then I use a delete statement to remove the values in the temp table.
Now, I have a column called Result, which stores the values of a radio button group (1, 2, or 3). I have a series of queries which count the number of times 1 or 2 appear (3 in this case, doesn't matter since it represents N/A. 1 = True, 2 = False, 0 = Null).
I'm having trouble getting the result of said query to store in a table. The statement is as follows:
SELECT [qryGetFail]![CountFail]+[qryGetPass]![CountPass] AS Total
FROM qryGetFail, qryGetPass;
This returns the sum of both counts, so I know how many questions were answered either Pass or Fail, hence I know how to score record. Here is my Append SQL statement as it currently works:
INSERT INTO tblAuditResults ( Question, Result, Comment, ACAPS, AuditDate, TeamMember, Auditor )
SELECT tblQuestions.Question, tblQuestions.Result, tblQuestions.Comment, [Forms]![frmAuditCreate]![txtACAPS] AS Expr1, [Forms]![frmAuditCreate]![txtAuditDate] AS Expr2, [Forms]![frmAuditCreate]![cmbTeamMember] AS Expr3, [Forms]![frmAuditCreate]![txtAuditor] AS Expr4
FROM tblQuestions
WHERE (((tblQuestions.Product)="4" Or (tblQuestions.Product)=[Forms]![frmAuditSelect]![txtVarProduct]) AND ((tblQuestions.Function)="3" Or (tblQuestions.Function)=[Forms]![frmAuditSelect]![txtVarFunction]));
This stores everything I need it to. But I cannot for the life of me get the statement to accept a value from a qeury and store it. I have tried adding another expression but it always just prompts for the value instead of pulling the value from the qryGetCalc.
Is there a specific way to have an INSERT statement pull a value off an active query?

Hi,
I know it breaks all the rules to store a calculated field on a table, but I've painted myself into a corner with the way I built this particular database, not good, I have repeating groups and basically the whole database is built this way. I need one form to store a calculated value on a table to solve a problem on a report that encapsulates the total of all the repeating groups. Before you start the lecture, I know I messed up, but this is way to far down the road to start over. Any help would be greatly appreciated.

I understand the conventional wisdom of not storing calculated values on the table, but I have a need to do do so. On my Input Screen I have a generated Certificate # derived from 5 single value fields keyed onto the screen. This certificate # is unique to those 5 single-value fields which should not be repeated. I want to store it on my Table as the Primary key with "no duplicates" so that if a keyer keys the same 5 single-digit values , thus creating the same Certificate #, he will get a MsgBox back telling him he cannot add a duplicate entry.
attached is my table and Input Screen.

I know that as a general rule one should not store calculated values in a table, but if I need to include such a value on a number of forms, and calculating that value involves manipulating an ADO Recordset, does there come a point where the performance hit outweighs the design "quality"?

Eventhough i know calculated control are for queries, I still need to store a calculated value of a sum. I have a form with customers, dates, locations. That form has a subform that contains the services done and materials used. This subform is in datasheet view. In the footer i have a control with =Sum([Price]).
So I need the value of this control to be stored in the table the main form is based on. I did an unbound control in the main form where the =Me!Subform.Form!.Textx will bring the value "over" Then for the on focus event the vba code Me.Total=Me.Textx stores the value. That is fine. The same works with a command button with the same vba code.
However i am asking if there is a more automatic way to get the value over without the unbound control/command button.

I am trying to create an accounting program on access and i got stuck on the final touches
I'll explain my situation in brief. I created two tables
/1 for the invoices (invoice number, client name, total)
/1 for the orders (order id, invoice number, subtotal)
And I made a relationship between those two and everything worked out well. I created a form/subform and put a text box in the subform to calculate the sum which worked correctly. And I exported the value of the sum to the main form and it's great.
The problem is that how can i make the Total field that belongs to the table invoice have a default value as same as the Expression (sum) so that the sum is stored with the invoice record.
i attached the picture in the attachments

Hey there,
I want to store a "calculated" value from a form text-box. By calculated, i simply mean that it is a textbox that contains the following Data:
=[MemberFirstName] & [MemberLastName]
Basically, the field is the Members Username, the text box is called "Username" and it needs to be stored in "tblMemberInfo" under "MemberLogin" so that it can be used externally for the website.
The value is only going to be calculated automatically by the form once, and then it wont need to be changed again, which is why i want to store it in the db.
Any ideas on how i'd go about doing this?
Cheers

Hello SBAXTER and company,
I was reading a post from a while back titled "MS Acess Security Logins" posted by pi4Paul. You sent him a sample security database. Since I just joined ASP I am not able to send you a PM with my email. If you still have it, please send it to me, or if anyone else has something similar that I can refer to while building mine, that would be great! Thanks a bunch!

I need to know if I can store data in more than one field, without allowing Duplicate entries.
Example: We have to send out letters with a claim number on it, sometimes we need multiple claim numbers on a letter, up to about 10 claim #'s is the most I've seen thus far.
We mail merge into Word to create the letters.
However, these claim numbers cannot be duplicated within the database and in order for this to work with the mail merge, I need several fields to store the claim numbers.
Fields are:
ClaimNumber
ClaimNumber2
ClaimNumber3
etc....
To be more specific. I probably have a bad data structure as I was kind of rushed and a little inexperience with putting the database together. It's for work and sometimes management just doesn't want to wait, they are so negative.
In brief, most everything is in 1 table and I know from reading this forum that I shouldn't do that, but that's another story.
Further, a claim# is tied together by the same claimant, the relationship code is what separates the claimant with the family, the insured id# is used for all claimants within the family.
You can also tie the claim# to a provider id#, some providers such as clinics and large hospitals have multiple providers that use the same provider id#, so a suffix code is used to separate the providers within that same #.
Please feel free to ask additional questions and I will give you the additional information you need to help me. Thanks again.
P.S. - Last year I created the database and this year I am improving it, so expect more posts from me in the future. I really appreciate all the help I get from everyone here!!!!

I want to be able to store 2 identical fields on the same table in the database. The copy will start off being the same as that input in the original field. 90% of the time the 2 fields will always be identical but the copy may be changed at a later stage. I looked into using the copy as a calculated field but found out these can not be updated. Is there another control I can use or do I have to code the population of the 2nd field specifically (in AFTER UPDATE EVENT?) myself. The added complication is that the original and copy must be selected from a combo box as all values are held in a separate table.
Also trying to make the second field = to the first field in the design stage of the table using default value
SO if I put default value = [table].[fieldname] I get an error stating could not find field 'table].[fieldname', and yes the opening and closing square brackets are missing from the error.

This could be one for you Mr Baxter.
I want to automatically create interview slots. On a form I've got an interview set up and there is a one to many relationship with a table containing interview slots. I want the user to key in the start time of interviews and the end time and the duration of the interview. It should then create the records (time slots) and display them.
I assume it will be some kind of append query, but to be honest I just don't know where to start.
Please help. A cyber pint goes to the boffin that susses it.
Cheers,
Recall.

Hi,
I have read that it's not recommended to put calculated fields on a table and they should instead be calculated using a query.
How about if I need to store that calculated value in a table (e.g. field1 + field2 = value in field3)
How can I do that please?
Thanks,
B

I am trying to create a calculated field in a query, that shows money owed from customers. I have 4 different job codes that have their own prices. I also have customers with the amount of hours they owe for, for each job. There are two customers that owe for two different jobs. I know how to write in : Money Owed: [price per hour]*[number of hours]. but i want to have only one line for each customer when i run the query. How do i combine??

I have a detail form, which has controls populated from a query.
For example,
Name Number
xxxx xxxx
This can be any length depending upon the amount of database records, so there might be 5 names, or 4 names, etc.
I then need to sum these in the footer. Is the possible?
I just seem to get #Error displayed when doing SUM([ControlBoxName])

I have a calculated text box on a form:-
=[AnnualSavings]/[SKUAnnualSpendInPounds]*100
But, if both the Annual Savings and SKUAnnualSpendInPounds text boxes have a value of 0 the result of the calulation comes out as #Num!. I assume this is the error because I am doing 0 divided by 0.
Does anyone know if this is the reason for my error and if so is there anyway of changing the #Num! back into a 0 so that I can submit it to my tables.
Any help would be greatly appreciated
