Dealing With Data Changes
Feb 4, 2007
What would be the best way to store data in a database that could change but without effecting previous linked records?
Let me try & explain a little better.
I have a table that lists materials with the cost price & sell price of each item
When I use that info to create a record I will only store the id no that the material is related to then link the cost fields to display the prices without storing the data again.
The problem I face is that in the future if any of the costs are changed in the main table then all linked records will also show the new amounts.
what's the best way around this?
Do I simply store the actual costs in the records when they are created allowing only the current costs to be used ?

I want the program to input an entry for every item with a value ranging from 1-300, according to sales data, according to the associated style.
I have to sort large amounts of Data and format them into a way I can deal with it.
I get two inventory lists twice a week from 16 stores.
I sort this data in two ways.
I do this by comparing an inventory list to a list of 300 of the best selling styles.
Currently, I input one list of inventory data in excel and then organize the items manually and respectively to sales data list in columns. Top 25 styles, 50, 100, 200, 300.
When I am finished, I have a certain amount of items in the top 25 styles, a certain amount in top 50, and so on. I color code the columns and write down the quantities and percentage of each category in the list..
if this is still confusing:
I have two tables.
one has the style numbers of which several items are in the category of a style number.
and one is the list I want to sort the previous list by. It has 300 styles that sold the best. they are rated from 1 to 300.
I want to organize all my items in each list by the 300 style list.
I have to do this twice a week, for 16 stores, for two separate reports.
ongoing basis.
is there a way of having the program do the numbers for me?
I am entering the data in excel physically . Is it possible to do this another way?
I am trying to sort the sales data sheet INTO the columns I have set up AND according to the styles that each piece of data has in common.

I have a database with student information that contains tables about their dissertation and graduation information. There is a field "academic year" noting their graduation year. I have a form for data entry that my data entry person likes to use in datasheet view. The form is based on a query that contains only current academic year records. When a new academic year arrives, I plan to create a new query for the form to feed from. i.e., "hiding" past academic year records on the form in datasheet view.

Hi everyone,
What is the best solution to deal with different currencies in an Access Application? After creating a table that includes currencies codes I want to use them in the form to present and calculate prices.
After choosing the currency from a combobox, the price field must be presented in numeric values with the chosen currency code.
Thanks in advance,
Best Regards

I have a database that has the basic tables of products, accounts and orders.
I need to figure out how to deal with returns.
Do I create a separate table and link that to the orders table for returns?
I haven't made such a large database file so I was curious if anyone had any information on how to lead me in the right direction. Or if there were any examples. (I've looked around but haven't completely figured out the best way to handle this.)
Thanks!

I have a database that keeps track of training hours for each employee. The Training Length is formated as Short Time. I just figured out that short time can only go up to 23:59:59. Some of my trainings will be over that. Does anyone know a way to get around other than splitting up my hours and Mins in the table?

I am using the following to extract date information from a text field as part of a query.
Narrr_Date:CDate(Left(Mid([si_narr_t],Instr([si_narr_t]," ")+1), Instr(Mid([si_narr_t],Instr([si_narr_t]," ")+1)," ")-1))
Due to users not putting the correct information in I will get the #Error in the results of the query.
I need to do a DateDiff on the results so I need to get rid of any values that come up with #Error.
Since I cannot ensure the date extracted by the query is correct, how do I deal with the error?

Setup
i have a form (frmCustomers) with a subform (sfrmJobs). As you might have guessed, it keeps track of customers and jobs. One customer may have many jobs. within sfrmJobs are about 300 or so controls for about 300 or so fields (mostly yes/no boxes) and at the moment contains two subforms of its own. customers have an autonumber CustomerID and jobs have a user-entered numeric JobID.
Goal
it has been brought to my attention that some jobs may just not work out and must be deemed as "cancelled." however, my client wishes to retain these records rather than delete them. in order to maintain the integrity of the reports, i would like to remove these records from the non-cancelled customer database and place them elsewhere, but still retain the ability to review them if need be (but NOT to modify them).
Problem
the job can be cancelled at any point down the line, meaning that a job could have nearly no info or nearly all the info, and everything in between. each job record has a ton of fields. i don't know how to cut and paste an entire record (except for doing it field by field, which could take forever in this instance) into a new table. in this case, it would be several records, since i have a list of materials pertinent to each job as well as a list of services necessary for each job - all of which would have to be removed and placed elsewhere.
Cry for Help
what is the best way to go about this? some ideas i had were creating a parallel table for each table used in recording all of the job information and just manually (well, via VBA and recordsets) copying, pasting, then deleting. another is creating a checkbox that when clicked disables every control for the cancelled job (but oy vey that's a lot of controls to code the disabling for) and then have it reflected in my reports that these are only from the NON-cancelled jobs. does anyone else have an idea?
help?
thanks in advance

Hello all,
Ok, let's see if i can explain this so that anyone trying help can understand. I have a form that's unbound (Music) with a subform (Arist Info)that is bound. The subform also contains two other Subforms (bound). The subform (Artist Info) contains a few Macros set up to do
some general searches with some Option groups and also one cmb box with vb code that access wizard wrote up. They all work great, with no problems at all when I open up the subform all by itself. It's when Main form is open where i run into some glitches. In then option groups all tgl & radio buttons work with exception to the two named ALL. I get a ballon message stating There is no field named
'GenreGroup or AlphaGroup' in the current record. Genre and AlphaGroup are the names of the option groups. The cmb box dosen't even work at all. There ars some other problems also but i'll ask for help later if i can reslove this. LOL I've attached a bare bone sample db to look at. I thought I was doing great learning new things every day, till I ran into this one.
Thanks for your help

I have a database that was populated using many excel sheets and one of the fields [partDescription] uses the # character over and over to represent "lbs". I realize that this is a wild card for digits in VB. Is there a quick fix for finding and replacing this character?

Hello...
I created a button that opens a link to a URL and copies information from a record to the clipboard to paste on this webpage.
The users are not using it correctly (they need to close the page each time they need to do the next record).
what i want to do is to close ALL IExplore windows via access if there are any open then open the URL again. Sounds pointless but we have to close it because of security.
Thanks.

I have a form that I designed that contains two subforms.The first subform is an entry subform so you can post the current client visits.The second subform I want to just display all prior client visits and make updates or deletions if needed.
It does not appear that I can make the first subform entry= yes additions allowed=YES in the properties.The second subform I want entry=No and addition=no..When I pull up the properties sheet for each of the subforms these options do not appear. They appear only on the main FORM, FORM property sheet. I thought I could create two new forms with the properties I desire and then copy them into the main form.

Hi all,
I am in desperate need of some advice. Today I set to work building some math functions in my queries to calculate delays/turnaround times for work, etc.
I have found that where there are null values in my table - the calculation seems to break down.
Let me explain...
In it's simplest form (I have removed some fields and will deal with DATE only, not TIME which is a seperate field) I have the following -
Date_Received
Date_Started
Date_Pended
Date_Recommenced
Date_Completed
I have the following expressions in my query -
Turnaround: Date_Completed - Date_Received
TimePended: Date_Recommenced - Date_Pended
TimeInactive: Date_Started - Date_Received
Workrate: Turnaround - (TimePended + TimeInactive)
The query calculation will only work when all fields contain a value.
For instance, sometimes the work may be started, then completed. Skipping the 'Pended' and 'Recommenced' steps.
Can anyone tell me what I need to include in my maths for Access to treat a null value in the table as zero? Or any other approach.
Please help!!!!!
Thanks
Rob :eek:

I have a large amount of field data that was taken by a data logger. Specifically, The datalogger has five temperature probes embedded in soil, and takes a measurement automatically once every hour for each probe. So the table has a Time field, and then a Temp1, Temp2,... Temp5 field. I need to be able to average the temperature fields. This within itself is easy enough, I just tell the query to find (Temp1+Temp2+...+Temp5)/5. However, unfortunately, because it is field data is is very common for one (or more) of the ports to be malfunctioning at any one measurement time for a number of reasons.
If, for instance, Port one does not have a value, then the formula I entered will not work, as it can't add a null value to numbers, and otherwise It would be dividing by five whereas there were only four values to average.

I am trying to use the expression below to transpose strings of 4-6 numbers (140504) to a string of 8 numbers with "20" in front (20140504). Some of the [Receive_Date] fields are empty or are 0, and in those cases, I need the expression to return a null value.
New_Receive_Date: IIf([Receive_Date]=0,"",IIf([Receive_Date]="","",Format([Receive_Date_YMD],"000000")+20000000))
The Format(...) part of the expression works fine on its own, but I am new to dealing with null values in my expressions, and when I add the rest of the expression, all '#Error' values are returned.

If my make queries in the data base and the source data base is another .mdb and the table names in the other .mdb which would be used for the queries are the same as those in the data base where the queries would be made......does anyone see any problems with that in the area of corruption or similar.
The queries made would be indentical to their counterparts in the data base where they are made and would serve the same purpose.
It would be a toggle type of thing whereby the recordsources for the forms in question would be changed.
For what I want to do it works perfectly but I am not sure if there would be problems that would only surface with longer term use and varied conditions as opposed to some short term testing.

I have data from a survey with qualitative responses. For a single qualitative question, I moved the ID & responses into a new table and categorized the response according to a bucket/theme, where each column is a new bucket. I now have 10 columns. Each response is represented in 1 or more columns. I used an excel formula to copy the response data into the column itself.
Example:
A1 // B1// C1 // D1// E1//... L1
ID // Response // Cats // Dogs // Elephants //.... Column 10
1 // I like cats // I like cats //(null)//(null)// ... (null)//
2 // I like cats and dogs // I like cats and dogs // I like cats and dogs //(null)//..//
3 // etc.
However, now I'm realizing that Access always wants to show data for all records, or at most I can limit using a WHERE clause in my query.I want to use Access to generate this report:
1. Section 1: Show all responses from the Cats bucket where there is data
2. Section 2: Show all responses from the Dogs bucket where there is data
3. and so on
I know how to do summary values, and I know how to do filtering that apply across the whole report, but this seems like more advanced filtering, where I want to see selective details differently for each field.

First I would like to give thanks to all the knowledgeable folks here who have helped me with my DB to date. It is working and every one is very happy and I have learned a lot.
So now I would like to add some more functionality to this existing project.
My DB is for data input of customers for a drawing. It has the following fields: Id, account number, first name, last name, date/time, score1, score2.
I t is taking a great deal of time for the users to enter in hundreds of entries a day. Most of the entries are customers who are already in the DB. I would like to get the fields to auto fill the data for existing customers say after the account number is entered. So after you put in the account the name and any other pertinent data would shows up saving users from typing it in again.
The first problem I am having is that this is still a data entry form and I can’t figure out how to be able to see the account information and still add new data to the record? The new data is a daily score they get.
Second I haven’t figured out how to call up the customers information from just the account field.
I’ve googled this and haven’t found anything terribly helpful.

i would like in a form for a combo box to be able to select an item from a table and input relating information automatically into other boxes in the form..
I have 3 tables: Table 1 has product code and product description.
Table 2 has invoice number company details, address etc.
Table 3 has product code and product description qty and invoice number..
Table 3 relates to table 2 by the invoice number and table 3 product code looks up the product codes available in table 1 and also table 3 looks up the list of products descriptions in table 1 using the combo wizard.
This means the wrong code can be put with wrong description.
What i would like to know is how i select a product description and the product code in the form fills out automatically?? i hope this makes sense please helppppp!!

I an trying to create a data entry form (IndividualsEntryFm) to input data for fields such as (First Name),(Birthdate) etc., these to be saved to the (IndividualsTbl)
I also have another table (NamesTbl) which has family names etc. The two tables are linked by a (MainID) field. I want a combo box on the individualsEntryFm so that I can select the family name. Then I wish the empty fields for the IndividualsTbl to be available to enter data.When I press the save button I then want this data saved, together with the MainID from the combo box to the IndividualsTbl.
I have set the IndividualsTbl with a (PersonID) field as an auto number each individual therefore has a unique PersonID but may well share the MainID. I'm trying to link many people to the same address.

I would like to filter data from a table using a query (from an data input form). The objective is to output all results if input form field is empty and to output results higher or equal to the type in the field if field is not Null. The query code is as follows:
IIf(IsNull([Forms]![Form2]![MaxDiffInput]);[Maximum operational pressure (bar)];[Maximum operational pressure (bar)]>=[Forms]![Form2]![MaxDiffInput])
However, is not providing any result when the input field (MaxDiffInput) as a value.

I am using Excel/VBA as a frontend and Access backend. The sheet2 stores the queue name and Queue number. We have to update the sheet1 from column L to column O by looking for the values from the Access table for the date selected from the comboboxes. Now In sheet 2 , it says Queue number and in actual in access table it is the combination of Type & Type1 & Type2. So we have to look for Type & Type1 & Type2 in the table and find out total Batches ,Total Envelopes,Total documents and total pages and then store the values in the ExcelSheet1 from column L to column O.
The following formulas will be used in the select statment:
Total Batches = count(BatchNo) for date selected
Total Envelopes=sum(Envelopes) for date selected
Total Documents=sum(Cases) for date selected
Total Pages=sum(Pages) for date selected

I want a Text Box Query on my form to display the Status, Workshop, Time, Enrolled and Limit. The problem is these values come from two different tables and the Enrolled value comes from a single field that contains the different workshops.
What I mean is: In Table[Attendees] a row contains a customer's Number, First Name, Last Name, Workshop and Phone Number. The workshops vary for each customer so one row on the table could have John Doe attending Cover Letter Writing and the next row could have John Smith attending Resume Writing. What I want is to be able to count the different workshops within the Field[Workshop] and total them and then display the total in a Text Box Query. I have a Text Box Query set up displaying Status, Workshop, Time and Limit as these values all come from Table[Workshops].
So basically I need to Query to also display a result that is the Total for each workshop from Table[Attendees] and display the total for each workshop in a Query with data from Table[Workshops].
Here is a link to an Example Database [URL] ....
I'm trying to avoid putting things on different reports and the like because the people using this are basically computer illiterate and if they have to click a button (no matter how well labeled) they won't do it and the information might as well not exist.
And if there's a better way to do it, I'm all ears. The only thing is, I have to update these workshops month by month. Since they are dynamic, I want to avoid creating separate tables for each workshop.
