Storing Values?
Mar 10, 2006
Howdy
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 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 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 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 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!!

Hello,
I am designing a query as i have been advised in the following Quote:
Doc ManNow, you write a couple of queries. As a parameter to the queries, choose a date that will be your archiving cutoff or split point. Usually the last day of some month or quarter. Doesn't matter as long as you are consistent about it. The technical cutoff will be, in effect, 23:59:59 of the chosen date. The first record to be KEPT will be 00:00:00 of the next day in sequence.
Query #1 - Compute stock on hand as of your cutoff date. Create a single stock-on-hand transaction with the cutoff date. Put it in a temporary table until you need it. This will be a two-layer query. I.e. a query of a query.
Query #1A - a summation query grouped by item number for all transactions earlier than the archiving date so you can get the "inventory of X at archiving date"
Query #1B - an append query that draws from the summation query and feeds it to the temp table. The stock-on-hand record will have the archiving date
.
I am able to get "inventory of X at archiving date" and append the results to a temporary table but I can't see how to append the "archiving Date" data itself to the same table as the "Archiving date" is entered via parameter prompt? Any ideas?

Hi all
I have a database that stores customer records and their associated insurance details. I need to be able to track any changes made to that record within a set time period ie if details are changed fine it is reported next time report is run. But if details are changed more than once in between reports then first detail change is lost.
I would like to work out a way that changes can be written to a ??seperate version of the table?? and stored in there to be reported seperately and not just the final change as is the snapshot nature of a report? Is this possible? Could I possible make another version of the main table appended onto it? I feel I 'know' what I need to do but not how to even begin it! Any help would be appreciated.

I am currently designing a contacts database for my business and need some advice on how to store addresses.
As I see it, I can either use a single field and carriage returns, or multiple fields which for some records may leave some blank fields.
The data will be used to perform mailmerges and will also be output to a contacts directory and I would be looking to display the address both horizontally and vertically. Is there a simple way of manipulating a multi line field so that it can be displayed on a form across the page on one line in a report?

Hi everyone,
I've recently begun building a database to keep track of stock at work. Nothing particularly special or difficult. I have a little bit of prior experience with Access and VB, but not heaps.
Basically, I've created a tables for parts, companies etc, and am relating all the data together.
At the moment I've made a form that allows you to enter a new part, with Part Number, Description, Category, Supplier, etc.
The complication comes when I want to create an ASSEMBLY of parts. I'd like to create an assembly (which has a lot of similarities to a part, in that it has a part number, description etc), and that assembly needs to store a list of parts that it includes. A simple assembly might include a few items, ie, a bowl of meatballs includes the bowl, a fork, the spaghetti, and 5 meatballs. A more complex assembly (a complete dinner for 5) might include 5 bowls of meatballs (a sub assembly), pepper and salt, 5 glasses and two bottles of coke.
I'm not sure how to best store this assembly data...
I can't really have a table with a finite number of "part" spots because the assemblies get quite large. I'd rather not use an ugly VB macro that stores the PartID's with quantities either, as that could get thoroughly out of hand pretty quickly.
I'm sure there must be a simple method for doing this, but without having a clue as to what it might be called I can't really look for it in help!
Any clues you guys could give me would be great.
Thanks
Col.

I've created a simple database in which we enter order id (automatic), date (automatic), customer, po#, shipping date, and ship via.
then we scan the order (which may be from 2-20 pages long) into the computer so that we do not need to keep actual paper (trying to save on office space).
these files then get inserted the scanned object subform (containing the fields scan number, object, and order id).
I'm realizing that because we'll be scanning quite a few orders that this may take up quite a bit of space, i'm wondering if linking the objects rather than saving them within the database will help.
the only problem with this is that if we move the files containing the actual scanned images, that the whole system will get screwed up.
Does anyone have any ideas?
Thanks in advance

How do I create a table relationship where a secondary reltated table stores past dates, status code and customer ID. For example: I want to keep track of the past dates that an order was revised and why it was revised. So, if I have a customer who was due for installation on 10/21/04 and status is PEND for pending. THen on 10/18/94 I change the date of PEND to 10/25/04. I want to keep track of the times it changed and the reason why. HOw can I make the program automatically create a record in the revision table storing the past code, reason and date using customer ID as key and teh revision table would allow multiple records for each customer ID. DId I make sense?

I'm building a questionnaire/survey database for my work. Everything seems pretty straightforward, but I'm a little unsure about how to store the survey configurations.
I'm assuming that the survey will change sometime between now and the end of time so I'm tracking survey configurations (which questions and in what order). Right now my "Configuration" table has two fields: ConfigID (Autonumber), Questions (Memo). The 'Questions' field is a space seperated list of question IDs. The other way I could've done it is to use three fields: ConfigID (Long), OrderNum (Int), QuestionID (Long).
I figure the first way is more memory efficient in the long run and it will take much less time to add a new configuration.
The way I'm doing things now works for me, but I'd like to know if anyone thinks I'm setting myself up for trouble down the road or if my way is actually less memory efficient (I'm not as concerned with processing time).

Dear Access Expert.
I have a choice of either calculating a field or storing it.
Specifically, I have two pieces of data ... departure time and arrival time which I have taken from another source. This other source also has the difference between these times. Currently, I am not storing the difference in a field as I have opted to calculate it in my database.
However, I am thinking that maybe it would be better to store it vs. calculating it because I have 35, 000 records and storage space is not going to be an issue.
What do you suggest if I my main concern is speed and effeciency?
Thank you very much.

Hi,
Firstly this is my first post so please forgive me if i do not conform to the usual way of asking a question!
I have an access database set up and it is working well, so far!
What I wish to do is the following, I am creating this for a cycling club to store race results...
I wish to store the time that they completed the stage in, how do i do this using the date/time field option when all it wants to do is store a complete time.
for example i wish to store 1 hour 12 minutes 15 seconds in the table as 1:12:15 for stage 1.
Plus they may have received a penalty, so in another field I would like to say store a 10 second penalty...
anyway you get the idea.... please could somebody inform me on the best way to do this, it has to be stored as a time so I can add all the stages up later and create a report!
Thanks in advance...

Hi
I have a database which picks up information from my accounts package. It has the following fields
ID,Name,Date,Ref1&Ref2
I need to extract the last ID number and store it in a table or somewhere and then extract the above information after that number into a csv file in the order above. It is used for my invoices and therefore when I do an import from my accounts package it updates all the transactions.
An example would be I say put 5 invoices on with a ID nr's of 1, 2, 3, 4 & 5 and output to a csv file. When I run the query/macro? it looks at the table with the last ID nr and starts from 6 and so on
I just need the ones I have done today. It has to be the ID number as each invoice is put on it gives it a sequential number, the dates could be different for each invoice.
I hope I've explained myself:)
Thanks in advance

Which is a more robust approach when designing an Access database in regards to storing images, such as TIFFs. Is it better to store the images in each data record as necessary or is it better to just store a path in the database that points to a location of where the image resides (on a hard drive somewhere for instance.)

New to Access and learning the hard way. Im sure this is an easy one, but sure would appreciate the help. I am trying to sum a group of cells and display the total, which i have done. But I also want to store this total in my database. So my question is, how do i move my calculated total to my field that has the "record source" bound back to my field in the database? Hope that makes sense. Thanks in advance.

if i have formula in a text box can that calculation be stored in a table???
example
sales total
sales tax
grand total
where grand total = sales tax+sales total
if the control is bounded to a field in a table once the formula is entered doesnt it loose the connection with the field???
right now when i enter a formula in a control it will no longer store it in the table but it will only show the result in the actual form..???

Hi all, another beginner question here.
I have a table of records which is is basically temp storage, once I'm done inputing information, an append SQL statement is run to move the data to its permament table, then I use a delete statement to remove the values in the temp table.
Now, I have a column called Result, which stores the values of a radio button group (1, 2, or 3). I have a series of queries which count the number of times 1 or 2 appear (3 in this case, doesn't matter since it represents N/A. 1 = True, 2 = False, 0 = Null).
I'm having trouble getting the result of said query to store in a table. The statement is as follows:
SELECT [qryGetFail]![CountFail]+[qryGetPass]![CountPass] AS Total
FROM qryGetFail, qryGetPass;
This returns the sum of both counts, so I know how many questions were answered either Pass or Fail, hence I know how to score record. Here is my Append SQL statement as it currently works:
INSERT INTO tblAuditResults ( Question, Result, Comment, ACAPS, AuditDate, TeamMember, Auditor )
SELECT tblQuestions.Question, tblQuestions.Result, tblQuestions.Comment, [Forms]![frmAuditCreate]![txtACAPS] AS Expr1, [Forms]![frmAuditCreate]![txtAuditDate] AS Expr2, [Forms]![frmAuditCreate]![cmbTeamMember] AS Expr3, [Forms]![frmAuditCreate]![txtAuditor] AS Expr4
FROM tblQuestions
WHERE (((tblQuestions.Product)="4" Or (tblQuestions.Product)=[Forms]![frmAuditSelect]![txtVarProduct]) AND ((tblQuestions.Function)="3" Or (tblQuestions.Function)=[Forms]![frmAuditSelect]![txtVarFunction]));
This stores everything I need it to. But I cannot for the life of me get the statement to accept a value from a qeury and store it. I have tried adding another expression but it always just prompts for the value instead of pulling the value from the qryGetCalc.
Is there a specific way to have an INSERT statement pull a value off an active query?

I am trying to see if it is possible to store colors in a form or table and then reference them while in VBA. What I am hoping to do is when I write all my code for command buttons to change On Got Focus, instead of writing xxx.backcolor = RGB (255,255,255) i could do something like xxx.backcolor = Forms!HiddenColors!Command That way if i want to ever change the color scheme of the db, I can change it in one place rather than hunt lines of code.
