Adding Feild Values And Storing In Another Field In Same Table
Mar 19, 2005
I have been struggling with this and would appreciate any help. It sounds so simple!!! I have 4 fields (Unit Price 1, Unit Price 2, Unit Price 3, Unit Price 4) in a Orders table that I want to add together and store in a 5th field (Sub Total) in the same table using a form. I am having problems with the sum and I am unsure how to get it to show in the Sub Total box in the form as well as the table. Thanks for your help!!

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"?

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.

I am sure this is simple but all my attempts at makeing a counter have failed thus far.

Hi,
I'm trying to create a table which needs some feilds to be automatically filled up when the control goes to it. Say my table has feilds, "size" and "result". In each row, the result cell should be filled up corresponding to the size value of that row. This needs to be looked up from an existing table.
Would appreciate any solutions!

I know that you shouldn't store totals in Access, but I can't think of a way around what I want to achieve and wondered if anyone had any ideas.
An item on stock will move from one location to another, I will need to list the 'balances' of this stock at each location, easy enough to do, but there are hundreds of item movements per day and the users do not want a history of movements to be kept but do require an ongoing balance.
e.g.
100 of the item moves from A to B, this movement record gets deleted, how would I know that the item stock at A has been reduced by 100 and B raised by 100?

I'm developing a database for the hospital I work in. One purpose of this is to keep track of patients with temporary invasive devices (there are many types such as urinary catheters, ventilators, etc.), specifically how many days each patient has a device for. Each device is associated with one patient only, but one patient may have many devices. Here's how the associated tables are set up:
1. tblPatients - PatientID (PK), LastName, FirstName, DOB,...
2. tblLocations - LocationID (PK), LocationLabel,....
3. tblDevices - DeviceID (PK), DeviceType, Device, DeviceDesc
4. tblDeviceUse - DeviceUseID (PK), DeviceID (FK), PatientID (FK), LocationID (FK) (where in the hospital was device inserted, e.g., operating room, bedside, etc.), DeviceStartDate, DeviceEndDate
5. tblDeviceDailyLog - DeviceLogID (PK), DeviceUseID (FK), DeviceDate, PatientLocID (FK) (area in the hospital that patient is in)
All primary keys except for PatientID & LocationID are Autonumbers; and the tables are linked appropriately.
Whenever an entry is made into tblDeviceUse, I want there to be new records to be automatically generated in tblDeviceDailyLog for each date between the Start and End Dates. For example, patient A123 had a urinary catheter from 1/1/2000 to 1/10/2000 that was inserted while the patient was in the ICU, but the patient was moved to the Medical Ward on 1/7/2000. So tblDeviceDailyLog should have 10 new records associated with this device, one for each calendar day, with the appropriate location for each day.

I am writing a sports database and have a query that displays a seasons fixture list in a form. One of the fields shows the points from each game played. (either 3 for a win, 1 for a draw etc). I can not get these points to be added up and displayed in a form along side the fixture list.

I have a field named Supplies Expense. As an analyst inputs a business's expenses, it may require multiple entries into this one field. What is the best way to accomplish this?
For example:
Supplies Expense (Field Name) [$0.00]
The analyst has the following data:
2009 Financial Statement
Paper $50
Depreciation Expense N/A
Ink $100
So, going down the list, the analyst goes into access and enters $50 for paper then later needs to enter $100 for ink.
What is the best way to combine these multiple entries into a single Supplies Expense field and allow for a quality check of the individual numbers at the end of the project?

Hello: Is there (simple) way that I can populate a field based on the values of two other fields? For example, in a list of new employees, if a new employee starts on Nov 30 and works in the Administration Department, his human resources contact is Mary. If a new employee starts on Nov 30 and works in Sales, his contact would be Fred. I hope this is clear! Many thanks!

Hey there, Im currently making a form so users can enter project information. For this particular project, the user must choose from a variety of options, and each option has a number value assigned to it for a rating. Now at the end of this form, I want a sum of the ratings, and then entered into the table. I am using a text box for the sum of ratings, and can get the sum of ratings to work on the form, but this data is entered as a 0 in the table. If anyone could help me find a way to put the actual sum in the table, that would be excellent.. thx a lot.
If it would be any help, here are the names of text boxes that I'm adding:
Health and Safety Rating, Maintenance Rating, Equipment Rating, School Size Rating, Student Enrollment Rating, SD Priority Rating, Project Requested Previously Rating
Those ratings must be added into "Total Rating"
Thankyou!

I am trying to add various values based on Select Case to the value of field. The problem I face is that each time when I get different Case in select statement, the value of the field rather changing adds the value on top.
Code:
Private Sub ProductID_AfterUpdate()
Dim qflPrice As Variant
Dim db As DAO.Database
Dim rs As DAO.Recordset
Dim sqlQry As String
Dim instID As Integer
[Code] .....

I am pretty new to access, I will get right to it.
I am scoring rating scales. I want to be able to enter just the responses from a person, say on 80 questions (preferably into a form), where all the answers are 0 to 3 and have Access add the questions into the right groups to calculate all the sub-scores of the rating scale.
For example, Scale A may consist of Questions 1, 6, 15, 29, 35, and 70
I need access to add those up and save them so I can use them in a report.
I also need access to add the frequency of certain questions that were responded to with the answer 3.
I have gotten Access to calculate the scores in a form by adding extra variables to the form, erasing the variable name out of the white box and putting in the syntax =[Q1]+[Q6]+[Q15], etc. in place of a variable name but it just sits there on the form and doesn't store it anywhere.
Thanks

Hello,
I wanted to catch a little advice if I may be so bold. I have a HTML form with a series of checkbox values.
Code:<form method=post action=form-test.asp><input type=checkbox name=drinks value='cocal-cola'>cocal-cola<input type=checkbox name=drinks value='sprite'>sprite'<input type=checkbox name=drinks value='lucozade'>lucozade<input type=checkbox name=drinks value='oasis'>oasis<input type=submit value='Submit'></form>
Normally I would gather these up into an array using ASP and email the split up comma separated values out to the client via an email.
Code:drinks=Request("drinks")drinks_split=split(drinks,",")'email drinks to client
However, this time I need to store those values in an access database. I am assuming that the client may want to run queries on the different array values, for example, how may people chose coca cola and sprite.
Is it better to store the value separately - one Ms access field for coca cola, one for sprite (which is what I thought I would have to do to create queries on this) - or can they be stored under one field heading "drinks" and queries be performed on different values within that field?
Could someone explain a quick way of doing the latter i possible in MS access and the SQL for querying?
Cheers,
trufla

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.
attached is my table and Input Screen.

In my database (attached), I need to be able to store multiple notes for tasks performed in various cities -- each note has a small description (more on that at the bottom of this post). For the "San Antonio, TX" task, notes "Heartbleed" and "BAT Scan" apply. From what I understand, this is a many-to-many relationship which will require the use of a junction box. My structure is like this:
tbTasks
TaskID (PK - autonumber)
Task
tbNotes
NotesID (PK - autonumber)
Notes
Details
jcttbTaskNotes
TaskID (FK from tbTasks)
NotesID ( FK from tbNotes)
My mainform (fmTasks) is based off the tbTasks table; my subform (subfmTaskNotes -- continous form) is based off the jcttbTaskNotes junction table. The Master/Child link for the subform control is TaskID. In the subform I have a combo box bound to the NotesID field in the junction table that allows me to choose a note.
My problem: I also have a "Details" text box in the subform that I want to be populated with the description of the Note selected in the combobox mentioned above. For example: if I choose the "Heartbleed" note, then I want that "Details" field to be populated with "Mitigate vulnerability associated with CVE-2014-0160". I assume it has to be somehow tied to the "Details" field of the tbNotes table, but how to implement that. How do I get the Details text box to display the details for each note?

I am fairly new to using access and am currently creating a database for a small bakery. They have new legislation whereby they have to list all their product ingredients and any allergens in the ingredients must be shown in bold.
So far I have 3 tables as follows:
Products (*ProductID, ProductName, Photo)
Ingredients (*IngredientID, Ingredient, Allergen)
Product_Ingredients (ProductID, IngredientID)
I have 2 forms set up:
one to input ingredients and a checkbox if it is an allergen
The other has a main form and subform to get ProductName, Photo and then a combo box in the subform to add ingredients.
Everything appears to be working ok but I have an issue with my subform. The combo box has no duplicates and lists the ingredients in alphabetical order as I require. However, if I view the subform separately from the main form I see that it is storing all the ingredients selected for each product. Therefore it is storing a lot of duplicate information.

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

The attachment is the database Im working on and I have a problem.
I need to add a supplier Product number in there some where so I could keep the numbe as reference and so it may be easier to enter items recieved.
in the form section, I will have Invoice with a sub form Invoice details.
I need to put suppliers Item number somehow so it would search and if the item is on the product list it would fill out the rest of the values.
should I make a separate table for suppliers product number or should I just include that into the invoice detail? I dont want to put it in the product table since I get same Items from different suppliers.

I have created the code below to add a new column to a table each month. This may not be the best database design but it meets our needs for now.
However I am having difficultly with the code below. The CreateField Function is unable to accept the parameter periodDate. Any Suggestions on this would be apprerciated
Function DateField() As Long
Dim colFullName As Object
Dim dbsCurrent As Object
Dim yearInt As Integer
Dim monthInt As Integer
Dim table1 As Object
Set dbsCurrent = CurrentDb
Set table1 = CurrentDb.CreateTableDef("103TblCustomerBalancesCombined")
yearInt = Year(Date)
monthInt = Month(Date) - 1
If monthInt = 0 Then
periodDate = CLng(yearInt - 1 & 12)
Exit Function
End If
If monthInt < 10 Then
periodDate = CLng(yearInt & "0" & monthInt)
Else
periodDate = CLng(yearInt & "" & monthInt)
End If
Set colFullName = table1.CreateField(periodDate, DB_TEXT)
table1.Fields.Append colFullName
End Function

Hi folks,
I am really struggling w/ the following & would greatly appreciate advice!
I want to add several Fields to a Linked Table in Access. The Access wouldn't let me do it because it is a Linked Table. What should I do?
There is also a nicely designed Form that goes w/ that Linked Table. So I figured that once I add the Fields in the Table then I can add them to the Form too. - But can't even add the fields yet....
HUGE THANKS in advance!

Now the problem I am facing is that in a new record I can type my values for all fields but an error(2465) is thrown when i try to save it
I suspect that when this field is added in the form it is not getting committed/saved into the table
how do i go about doing this?

I am building a DB for my college, it is needed to replace a spreadsheet they have in place. The spreadsheet is used to monitor and track Students grades.
Each unit a student passes gives that student a certain number of points, the number of points depends on the grade (e.g. a student will get more points for a B than they would for a C). The point of the DB is to input all the students grades so that student can see how many points they have.
I was wondering if there is a way to add a value to a field, so if I put in a field that a student got a B grade the database would know how much a B grade is worth points wise. Each field should be added together to generate an overall score. Is this possible?
