Tables :: Accounting For Missing Values In A Calculated Field
Mar 24, 2014
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 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 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 have been reading previous post s regarding the storing of calculated fields. Basically everybody says don't do it. However, if I don't I am not sure how to achieve what I need to achieve.
I am storing data on tool vibration levels. Data is input for X, Y and Z axes and a vector sum (total) is calculated on the fly using a query. So I only ever store X,Y and Z.
Ultimately I am looking for this database to be able to give me useful statistical outputs in particular a range of vector sums for a tool type. If I don't actually store the vector sum for each test then how I am ever going to report a range? The data would never change for each test as these become statictics, it's not the same as working out rates for example which may vary according to parameters.
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.
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"?
Currently I have a calculated field in my table; however, under certain circumstances I need to change the value to another value which is not related to the calculation. I understand that the calculated fields are read only (why is that?), so I was wondering if there was any way to change values within a calculated column without actually changing the expression itself.
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?
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]
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’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'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:
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?
So I have a simple table with Date, Points Earned, Points Used and Client ID number. Id like to tally the points for each client ID, after each time they either use or earn points. How do I do this?
Order ID(Autonumber) Client ID(Text) Client Name(Short Text) Install Gross Rate (Currency) Install Discount Given in % (Number) Install Discount Given in GBP (Currency)
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.
Is there anyway to set a calculated field as the primary key? Or how to duplicate the value of a calculated field into a new field and set the new field as the primary key?
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 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.
i want to insert a calculated value of a e.g field6 (field4 * field5) in forms into the database table. by using expression builders in my forms. i have made that feild and on click it shows the calculated value but on filling in the rest of the form and clicking on Insert button does not update this calculated field but iserts all other fields.
