Tables :: Get Rid Of Calculated Field In A Table?
Sep 13, 2013
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 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.

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.

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)?

Access 2010.
Have a table with columns of data which I want to total at the end of each row. The Calculated Field does this simply enough but it only seems to be able to add whole integers? How do I get it to accept and add values to 2 decimal places?

I am trying to create a calculated field in my table, I am trying to use the following code:
DatePart("ww",[Gas]![Date Opened])
I receive the following error message: "The expression DatePart("ww",[Gas]![Date Opened]) cannot be used in a calculated column."
Access 2007 - I really need to be able to display the week number in the table, based on the Date Opened field.

I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.

I use access 2010.
I am assuming by the error code, one can not use a calculated field to calculate another field.

I’m trying to create a function (by combining IFF with Dlookup) that will automatically complete the name off the Team Leader when the Agent Name is equal with the field from my table.So, I have a table called BAZA imported from Excel with the fields: Team Leader|Agent Name| Customer Number|Date of interaction|Reason of interaction|, and another table called Agents imported from Excel with the fields :Agent Name |Agent User . The User filed is the same with Agent Name from BAZA, but I also have in Agents table some Agents that are not in BAZA, that never had interactions with customers.I what to add another calculated field in Agents Table that contains the Team Leader of agent. Till now I tried this:
-create a query called Sort3 based on BAZA where i have Team Leader|Agent Name with no duplicates
-the function i tried is =IIf( “[Agent User] =”&[Sort3]![Agent Name], Dlookup(“Team Leader”, “Sort3″,”Agent Name=”&[Agent User], “Different Team Leader”) ….. it seems to have some errors
-the data type is text.I use 2010 version of Office.

I'm currently building a database and one of the things that I must make is a "warning", more like a symbol on a continuous form, that is there, if the task is wanted by a costumer.
I have a Yes/No field in database, which decides that. Now I need to figure out how to make it appear on form. I thought about making a calculated field, that would display some warning icon.
Now my question is, is it possible to add an icon to a calculated field and if possible, how?

I have a calculated field that is a total based on 5 other fields. These fields are rankings of priority on individual categories, while the calculated field is a total priority ranking for the entire record. (A ticket) The 5 categories are prioritized, and the calculated field runs it through our equation to determine the overall priority of each ticket.
Now, some tickets don't have individual priority numbers in their categories. Therefore, no total priority number is calculated in the calculated field. We would like these tickets to be given a manual total priority, but we can't manually enter numbers into the calculated field to do this.
Is there a way of saying this to the calculated field... "Use the equation to run the individual categories to come up with your total. IF there are no numbers in those categories, reference the field 'Manual Priority' to find your number."
This way, we'd like to keep all of the total priorities in the calculated field. It's just that some of them have to be manually entered because there will be no individual priority categories to calculate the total by.
The current formula for this total priority field is...
(([Size of Financial Risk?]*20)+([Impact on Internal Customers]*15)+([Non-Financial Impact]*20)+([Impact on External Customers]*30)+([Estimated # of Clients Impacted]*15))
I'd like to say, "Do that... or use this manual field if that equation turns out to be nothing."

I have a problem when storing a calculated field with two decimal points. If I set the field to double, fixed, 2 decimal points. For the field it will show the calculations as:
21.364 as 21.36
21.563 as 21.56
21.272 as 21.27
Which is how I want it to be, however when I run a summary of the field rather than showing 64.19 it calculates as 64.20, I know that this is the correct figure but is there any way I can get it to show me the 64.19?

Then I designed a Query to calculate the Install Net Rate
Query
I selected
Client ID
Client Name
Order ID
Expression: [Install Gross Rate]*(1-[Install Discount Given in %]/100)-[Install Discount Given in GBP]
I run the query, but only ONE order calculated correctly, rest of Orders returned blank row.

I am trying to make my primary key in my table a calculated field.
I want the field to be subject + catalog + topic no. The only problem is that there is not always a topic no.
How would I write this expression?

I have three columns where A is a number, B is a number and I want to make C = to the greater of the two. i.e.
Col A = 10, Col B = 12 therefore Column C = Col B or Col A = 12, Col B = 10 therefore Col C = Col A

Access 2010 database.
I am trying to get an average from several numbered fields, which some may occasionally be blank.
=Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0)
I get an error message that says "The expression =Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0) cannot be used in a calculated column. This is a hypothetical expression being used.
The real expression is ...
([GC A1 - 2]+[GC B1 - 2]+[GC C1 - 2]+[GC D1 - 2]+[GC E1 - 2]+[GC A2 - 2]+[GC B2 - 2]+[GC C2 - 2]+[GC D2 - 2]+[GC E2 - 2])/10
This expression works great until a field is left blank, and then the average box is left blank.
The fields I am trying to add are Long Integer. Would that affect it?

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 table of transaction data, I want to count the number of successful customer transactions but the table includes cancelled transactions with a negative value. I was therefore looking to create a new calculated field for customer count which report either "1" or"-1" depending on if the price is positive or negative. The idea being a count of this would give the customer count. The expression I am using is:
IIf([Price]>=0, 1, -1)
The problem is it I get an error message saying "The calculated field cannot be created" "verify that expression "IIf([Price]>=0, 1, -1)" includes fields that exist in the current table"

Hi,
I have two tables:
Table A provides total sales volume of the UK shoe market from 2000-2007.
Table B provides the sales volume of different shoe manufacturers from 2000-07.
I want a third table created, called Table C. This should look exactly like Table B but instead of sales volume it shows percentage sales that are calculated by using the figures in Table A and B (i.e. [sales volume from Table B/total sales volume from Table A] * 100).
Could someone point me in the right direction please (assuming that such a table can be created, based on a calculation of figures in other existing tables).
Thank you.

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 great with Excel but not soo much with Access 2010. I Excel, what I needed to do was very simple but duplicating what I did in Access is not soo easy.I am trying to calculate billings for FSA & HRA. I have set up one table with all the data. I want to add columns to the table to calculate:
1. Is there an account balance-excel formula:
2. If the account is still active
3. If the plan year run out is "active runout" or "runout over"
4. calculate each account type with a rate *count of FSA accounts = total to bill
Here are my excel formulas that for the life of me I can't get to work.
Account balance==IF(V2="HCRA",(IF(AB2-AD2>0,"Available Balance",IF(AB2-AD2=0,"Zero Balance","Negative Balance"))),((IF(AC2-AD2>0,"Available Balance",IF(AC2-AD2=0,"Zero Balance","Negative Balance")))))
Active runout/runout over=
=IF(AG2="YES","Active Runout",(IF(S2=W2,(IF(AF2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")),(IF(AE2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")))))
Active account=
=IF(D2<$AJ$1,"NO",IF(W2>$AJ$1,IF(S2=W2,"YES","NO") ,"NO"))
Can I have calculated fields that refer back to a calculated field?
