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:
View RepliesI have a table that is a list of all of my events. Each record of events should have a child table that list all of the things that happened at the event. When a new record (event) is added how can I have a new child table created and linked to that record. Also I have a blank table to serve as a template for what each child should look like. How do I make sure this occurs? The child tables can have the same name as the index. I am just using numbers 1- for the index with 1 being the first event and so on?
View 8 Replies View RelatedI 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
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)?
View 3 Replies View RelatedHi 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... :)

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.

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?

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.

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 a subform with a lot of fields in which require input. I have set the tab order correctly so they go through in sequence. However, I have found when I tab out of the last field. Its creates a new record which I dont want.I want it to either return to the first field to just stop.

View 10 Replies View RelatedI've read over and over that calculated data is bad, that's fine with me... but here is my dillema...
I have four fields that interact with my calculation in a single form. There is only one table in the database.
AmountF (The stored data in the table) (amount financed)
FC (calculated by =[amountf]*.25) (finance charge)
Amount Paid (used in calculation of total due)
total due (calculated by =[amountf]+[fc]-[amount paid])
The math already works, everything works. I can choose to print the form and it looks great. However, I would like for it to (when I'm done printing the form) somehow save the total due data to the AmountF column in the table. AmountF is in the same line as all the other information, so I would like it to not create a new record just update the old one.
All four of these fields have a text box in the form for themselves.
