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?
View RepliesI 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?
Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.
For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.
If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.
I am "OK" when it comes to figuring out a formula in Excel, but Access is much different for me. I am looking to set up a calculated field in a report.
The result is find the Client-to-Staff ratio but there are two possible conditions:
CONDITION 1: If VacantFTEE = 0
ActiveClients / (DirectFTEE + DetailedFTEE + ProvidedFTEE)
CONDITION 2: If VacantFTEE > 0
ActiveClients / (DirectFTEE + VacantFTEE + DetailedFTEE)
I am presuming I need some sort of IF/OR statement to make this as 1 formula, but I can't seem to make it work.
I have a calculated field in a query. The field name is TotatPt (this is to calculate the total points students have earned during the term). The expression is as follows:
Code:
TotalPt: [Att1Pt]+[Att2Pt]+[Att3Pt]+[Att4Pt]+[Att5Pt]+[Att6Pt]+[Att7Pt]+[Att8Pt]+[Att9Pt]+[Att10Pt]+[Att11Pt]+[Att12Pt]+[Att13Pt]+[Att14Pt]+[Att15Pt]+[Att16Pt]+[Att17Pt]+[Att18Pt]+[Att19Pt]+[Att20Pt]+[Att21Pt]+[Quiz1Pt]+[Quiz2Pt]+[Quiz3Pt]+[Quiz4Pt]+[Quiz5Pt]+[Quiz6Pt]+[Quiz7Pt]+[Quiz8Pt]+[Quiz9Pt]+[Quiz10Pt]+[MidtermWritPt]+[FinalWritPt]+[Proc1Pt]+[Proc2Pt]+[Proc3Pt]+[Proc4Pt]+[Proc5Pt]+[Proc6Pt]+[Proc7Pt]+[Proc8Pt]+[Proc9Pt]+[Proc10Pt]+[Proc11Pt]+[Proc12Pt]+[Proc13Pt]+[Proc14Pt]+[ProcPracPt]
I think this should be no complicated expression (though a bit long) and should just add the fields together. But what I get is that the calculated field appears as expected for records with an odd primary key (1, 3, 5, 7, ...) and turns out blank for records with an even primary key (2, 4, 6, 8, ...)!
I've attached a screenshot.
i have 4 supplier tables with identical field names but different databases in sql.I want to have them all in one table and only want the information for reference i do not want to edit any of the data.I need to create a new primary key number for the complete table. The data will need to be refreshed as the data comes from MMS Sage looking at company PLsuppliers.
I have tried a linked SQL union view- but this has no primary key.I need to keep the Primary key consistent as the data saved in other tables will use this field.The overall goal is creating a Purchase order system and this list will be my complete supplier list.
I have a query which returns a calculated percent. I have ordered that in descending order, and now want to see the top 50. So (In Access 2010) I entered 50 into 'Return'. But it returns all of the records!
Is this because pct is a calculated field? How can I correct this? The SQL seems to be correct.
Code:
SELECT TOP 50 HeciFail1.POHECI, HeciFail1.POQTY, HeciFail1.FAILQTY, IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) AS PCT
FROM HeciFail1
ORDER BY IIf(Nz([FAILQTY])>0,Round(100/([POQTY]/[FAILQTY]),0),0) DESC;
I have a numeric field (long integer) in a table. I've set the format to fixed. No matter what I set the decimal places to, auto, 0 or 2, when I enter a value of 0.71, it displays as 1.00
In my form, I've also set the field property to fixed, but it displays the value as 1.
Hi guys,
I am having problem with a query.
I have to tables. One named wire and the other named Input.
As my title says there is not unique ID for the tables to relate.. the only thing to relate is one ID where is not unique for all the rows
In the Wire Table I have 3 rows using the same ID, lets say 123.
In the Input Table I have 1 row using the same ID as above, i.e. 123
I need to select a couple of fields from Wire Table and 1 field from Input Table
The only relationship I have is the ID 123.... since the ID in Wire Table is repeated in 3 rows.... I would like to use the same value from the Input Table to be the same for the 3 rows in the other table.. Below is an example:
Wire Table:
ID Group
123 A
123 B
123 C
Input Table
ID Description
123 Analog
My wanted result would be
Group Description
A Analog
B Analog
C Analog
I tried using the Left join or Join function, but somehow the resulting table has many duplicates of the rows...such as:
Group Description
A Analog
A Analog
A Analog
A Analog
A Analog
B Analog
B Analog
B Analog
B Analog
...
Any Idea on whats going on and how can i solve this problem????
Thanks in advance. Your Help is much appreciated
I am trying to set a primary key on two fields. the problem is that the one field is null for some records. They will eventually fill them in. However, because it is null now it will nowt let me set it as a primary key. I tried setting the field, in the properties, with a default value; but it would not take it.

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

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'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?

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 have a table with primary key, application ID ( this is autonumber type).
In a new table i want the primary key, copy number, to take a value that consists of the application ID and add an autonumber to it.
e.g
Their are two copies of Application X which has an application ID of 19.
so the first copy will have a copy number of 19+1= 19 1
and the second copy will have a copy number of 19+2 = 19 2
is this possible and if so how or are there any other options?
I am trying to create a one-to-many relationship between these two tables. I want to be able to access the 3 fields on the [Processors] table within reports based on [AllItems]. [AllItems] is a listing of account activity where the [AccountNumber] repeats. I have every field set as the "Primary Key" on [AllItems] as that is the only way to avoid importing duplicate data. I am getting the error: "no unique index found for the referenced field of the primary table"

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 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.
