Insert Calculated Values In A Table Field?
Mar 17, 2014
i have a subform which contains a lot of calculated values. fields which calculate values are located both in master form and subform. i use those calculated values in various reports where i have to insert formulas again. so i have decided to insert calculated values in table directly. i can use update query but i am unsure how to trigger it; and how to keep fields updated everytime a value is changed.
main form fields = [gsm] , [rate]
sub form fields = [pages], [qty], [gsm]*[rate]*[pages]*[qty]

I have what is probably a stupid question but I've been struggling with this one for a while. I have an ordering database which has an Orders table (containing Order ID, Date, Supplier etc) and an Order Line table within which I have a combo box for Product name, supplier, price, VAT rate, Line price etc. At the moment, I have the order line table as a subform within the Order form (run from the Orders table). The problem I'm having is the subtotal and total fields. At the moment these are in the Order Line table as I cannot figure out how to get these in the Orders table. In summary, can I make a calculated field in one table that calculates values from another table (linked by Order ID)?

I am working on a timesheet application which allows users to insert multiple timesheet entries in a grid style format. the first row is visible and to add another row users click on a command button which makes the next row of fields available and ready to fill in and so on and so forth. I need the fields to be unbound and then when the user clicks on a save button for example then it inserts those values into the relevant table. Table name is tbltimesheet, field names are id, companyname, project, activitydate, activityhours, activitynotes, username, userid

I have a field in a form which displays the Sum of 10 values from other textboxes. I want to display the values of that calaculated field in a report and somehow I am stuck. I am running the report based on a query.
How would I get those field calculation values to display in a report?
Thanks

Hi
I am creating an employee db, with fields including employeeID, surname, firstname, partnerSurname, partnerFirstname, partnerID. As some partners work at the company, I want the partnerID to list (thorugh a value box) employeeID's that match surname to a partnerSurname and firstname to partnerFirstname.
Is this possible? Any help greatly appreciated.
Thanks in advance.

I have a table that stores information for multiple behavioral surveys (numerical values). My goal is to add the proper fields that compose total scores value for each respective survey (do a summation of scores). Now, under design view for my table, I see that I can add a calculated field. When I create this calculated field, I can use the Expression Builder to do a sum of the proper fields (the fields that compose a total score for a survey). The only problem that I'm encountering is that if a field that is part of a survey is missing information, the summation disregards the rest of the values for that survey.
How can I account for these missing values so that, if 1 out of my 9 fields have information, I will still get a summation score for the 9 fields? I want to be able to do this without having to change the value of the missing field to 0.
In SPSS I can easily do this by computing a variable and using a code like this:
SUM.2(field1, field2, field3, etc.)

I have a button on a subform that becomes visible if there is no records in the source of the subform. When clicked I want to run a query that will insert a record on to the source of the subform. There is one field in the query that I need to get from the parent form.The first part works OK - the button is visible when the source file to the subform for this main form record, is empty.
If I run the query against the source file it inserts the new record after it has asked for the value of the variable field.My problem is that when I try to run the query when the button is clicked It can't find form![ClientFileFrm]![ClientId]..This is my code on the subform
Private Sub Form_Load()
If Me.RecordSource <> "" Then
If Me.Recordset.RecordCount = 0 Then
Me.AddSettingsButton.Visible = True
[code]...
The ClientFileFrm is the main form.I can't seem to reference the clientId variable back to the main form.

I need to display a value from a table in a text field on a form based on another text field on the same form.
The table has records as follows:
Month/Year xx Month No xx Year No xx Month ID (xx shows break in columns)
Jan-06 xx 1 xx 2006 xx 24
Feb-06 xx 2 xx 2006 xx 25
Mar-06 xx 3 xx 2006 xx 26
Apr-06 xx 4 xx 2006 xx 27
May-06 xx 5 xx 2006 xx 28
Jun-06 xx 6 xx 2006 xx 29
Jul-06 xx 7 xx 2006 xx 30
In one text field I use the DateSerial function to calculate the value of the previous month (e.g.Jul-06). I need to return the MonthID value to the second text field based on the value stored against it is the table, so in case of Jul-06 it would show 30 in text field 2.

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"?

I am trying to get a value from a textbox into a table I created...
The textbox "calculates a number based on which radio button is pressed example if radio button 1 is pressed it returns 0 if radio button two is pressed it returns 8 and if radio button 3 is pressed it returns 15." I need to save the 0,8, or 15 depending on which radio button is pressed into the table...
I know you aren't supposed to store calculated values into a table but the report would never need to be changed and it just saves a new one each time with that being said anyway to make this work would be very useful!
Also how can you use the answer of calculated textboxs in other calculations?

I'm trying to write some Code with the target to take a value from a textbox (out of a form) and a pregiven value (in this case = 2) and enter them in a new record in a table. But only if there is not already a record with the exact same combination of these to values. When done, the same button should proceed you to the next form (but this code is not already implemented in the fragment below) even if no values are added because they already exist in this combination.
Code:
Public Function GetID_PatientStudiesGroup&()
GetID_PatientStudiesGroup = [Forms]![frm_PatientStudiesGroupTZP]![ID_PatientStudiesGroup]
End Function
Private Sub BPRS_T1_Button_Click()
Call GetID_PatientStudiesGroup&
Dim strSQL As String
[Code] ....
As you can see, I tried to use a function to refer to the value out of the form, because I didn't find out how to refer to a form in an SQL Code.
Just to give you a better overview: The table where the information should be added is named "tbl_PatientStudiesGroupTZP". The form where you find the Textbox "ID_PatientStudiesGroup" (with the value I need to transport) is named "frm_PatientStudiesGroupTZP". Every part (except the WHERE NOT EXISTS part) worked perfectly for itself, but not when thrown together.

I am creating a database to keep up with the expenses for my art business. I have a table for Vendors with a field (Mileage) for one-way mileage that I enter manually (EX: 11.8 miles). Then I have a calculated field that basically just multiplies the Mileage field times two to get total mileage to and from my house to vendor location. (Total Miles) {The reason I want to do this this way right now is because I didn't keep up with my mileage this year and I am having to look up the distance from my home to each location)
Then I have a "supplies" table where I show the date, the vendor, the item, cost, etc, and I want to add a Total Mileage field based on the calculated Total Miles field in the Vendors table that will automatically populate based on the vendor of each transaction. I just can't remember how to make this work and I know just enough SQL to be dangerous.

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

Hi folks,
Is there a way to have a calculated field within a table? I have a table that I've added four fields to: AmountIT, AmountRE, AmountKK, AmountRes. I want to be able to sum these four fields to give AmountTotal, but is there a way to have in a table?

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... :)

I have two tables.descriptions I'd like to relate and use to find/replace in bulk.
[Checking].[Description] (with the source data)
[Rename].[NewDescription] (with the correct data)
I'd like the values in [Checking].[Description] to be replaced with the values in [Rename].[NewDescription], including those that are "Like".
Examples:
[Checking].[Description] = Geico 12345
[Rename].[NewDescription] = Geico
[Checking].[Description] = Geic
[Rename].[NewDescription] = Geico

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.

Is it possible (and logical) for me to create a table with a calculated field from 2 other fields in the same table? Example; I have a long time field (mm/dd/yyyy hh:mm:ss) aka StartTime, and a long time field EndTime. I would like to subtract the StartTime field from the EndTime field to get the total time elapsed, but in hh:mm:ss format. I can get it in hh:mm format, but I really need the hh:mm:ss format. Any Ideas? :cool:

Hello,
I have been reading various threads about this subject and I know that one shouldn't store a calculated field in a table.
I believe this may be an exception to the rule (but I could be wrong).
I am making a pricing database that will use a few manual inputs and the rest of the fields will be calculations (gross/profit margin, expenses) based off these inputs. We need to have these calcuated fields stored because they are essential to the pricing decisions and we will have to go back and access these fields at a later time. Another reason for this is because there will be at least one report that will be used to compare prices and calculated fields associated to a certain product by company, program, item type, ect...
Any help would be greatly appreciated.

I've learned the hard way about using calculated fields in a table. I used on while building in Access 2010 for users that will be using Access 2007. Once my testers pointed out the error message, I did some research and realized my calculated field was the problem.
So, I created a query to replicate the calculation, deleted the offending field from the original table and redirected everything to point at the new query vice the original table.
However, my testers are still receiving the error about needing version 14 to access that table. There isn't a calculated field there any longer, but they still can't access that table. Did that calculated field put some sort of taint on my database that can't be removed? I'm not sure what to do. Do I need to start over, so that a calculated field was never part of the database to begin with? If so, how much of my existing one can I reuse?

Access 2013
I am trying to add some numbers together for a number of fields, of which at least one field will either be 0 or empty. I am trying to use the following formula in a calculated field in a table:
IIf(IsNull([Price Increase %]),[Total],([Total]*[Price Increase %])+Nz([LumpSumAnnualIncrease]))
Access returns an error statement: The expression XXX cannot be used in a calculated column.
Is there a different formula I should be using, or a work around, other than using the formula in a query.

I did the calculated fields in my table but in my datasheet they are not appearing. Are they not supposed to show there? I have not created any forms yet.
