How To "Relate" Tables
Jul 6, 2007
Hi I have read quite a few posts and googled loads after advice fron some of the forum users and am still confused (which is not hard :confused: )
I am in the process of designing a new database to keep records for patients (medical type!)
At the moment I am designing the tables and am somewhat confused as to how I would link these in the future?
The tables I will have are
Patient Details (First Name, Last Name, Date Of Birth, Address etc...)
Treatment Table (various fields relating to a treatment)
Consuambles used Table (induvidual items used to treat a patient and the quantities used, bandages plasters medications ect)
Vaccination Table (Various field relating to vaccinations)
Accident Report Form Table (various fields relating to a treatment that was need because of an accident)
What I hope to be able to do in the end is to "pull" up a form / report that will show all the treatments and consumables used for that treatment, Vaccinations and accidents a particular patient has had?
I really would appriciate any help anyone can give me on this but more so if they could explain it very basically
Cheers guys

I am trying to figure out create a new table from two other tables. It is a tax document and one has a pin field that is unique and the other the pin field is not unique. So in the table the that doesn't have a unique pin field, the pins occur multiple times for all the different tax enitites people pay to. I need figure out how to make one table that combines these too. I have tried using the relationshop function but i am not sure if this is what i need to do and i am not that familiar with access. If there is anyone that can help me please let me know. or if you need any more information.
Thanks

I'm sorry if this is obvious, but I have asked local professionals and scoured this site for answers before posting...
I have a database that I'm using to store and analyze language samples (basically, the mistakes that students make when trying to speak in another language). For each bit of language, I want to be able to say what domain the mistake belongs to - e.g. the 'clause', 'phrase', or 'word' domain. I have a table containing the five domains. I also have a table for each of these domains, containing the specific types of mistakes relevant to that domain. It is conceivable, but unlikely, that I will ever add to the domain table, but highly likely that I will add types of mistakes in the five related tables.
As I analyze bits of language, I will be appending each analysis (record) to a table as shown in the attached image. So far so good. The part that I cannot fathom, though, is how to display (let alone perform calculations on) this data: While the ErrorDomainID is a foreign key to the ErrorDomain table, the ErrorUnitID could refer to one of five tables, so that an ErrorUnitID of 2, for example, could refer to one thing if the Domain is 1 but quite another if the domain is 1 or 5 or whatever.
I've tried all kinds of coding and SQL workarounds, but I have a feeling I'm just missing something very basic here. If anyone could offer some guidance, I'd be extremely grateful!

Hi,
I'm having problems relating a pivotchart with search criteria automatically after the search - all on the same form. This will be a nifty trick if it is possible, and I can imagine other uses for a form like this.
Without being overly wordy, I attach a mdb in hopes that someone with a bit more skill than I will take an interest and set me on the right track.

Hi, I'm in the process of building a program in access 2003 for estimating roofs, I've ran into a little problem, as described below. any suggestions would be very useful
Populating the text box’s that relate to the chosen combo box’s with the sum of a calculation.
In other words if X combo box is chosen (There are many combo boxes to choose from) populate xx text box with the sum of a calculation.
Refer to the print screen example of my program: http://www.roofmart.net/Rest.asp
Notice under the label felts the 15lb 36” felt combo box is chosen and it displays the value of 11 and next to the combo box is a text box that displays the value of 25 The calculation will be (11*25) = 275 this value of 275 must be added to the text box values that are being shown in the forms header under 30yr where it reads $4,606.80 and 40 yr $6002.80 only, this is because the 30yr comp and the 40 yr comp combo boxes are the only chosen roof types under the label roof types above the felt label.
Hopefully this makes sense.
Thanks -- Any help with be greatly appreciated.

How does Access relate a label to a control?
We can delete the label, and then re-'attach' it, but there seems to be no visible property that retains this information - in either the label or the control (only done the detailed comparison for text box so far.
The reason for this is to be able to export enough data to recreate an Access form in html, and I need a label value if it exists. (And for most controls, of course, it does!)

Currently trying to build a database for customer management and order placement/tracking. Want to set a couple of rules so that if I for instance click yes of billing and shipping address the same that the database will automatically fill the shipping address with the data I inputted for the billing address in the same table.
The other issue I can see I'll run into is, I want to be able to select one of the company ID's (made up of a three letter abbreviation of the full company name) in the product ordering table and it will automatically fill in the rest of the customer data (phone, email, address etc) data into that form.

What I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.

I have 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)

I'm using the MS Access 2010 ExportwithFormating action to export three tables to a single MS Excel 2010 workbook. The action overwrites the first excel worksheet each time instead of saving all three worksheets in a single excel workbook.
How can I export three tables into a single excel workbook.

I have created a table that acts as a header for my data and a second table that acts as line item data. What I need to do now is add a second child table that uses the line item data as its parent table and stores associated line items for each record. Is this possible?
This is a skeleton view of what I'm going for:
Master Table:
tlbAuditReportHeader
- AuditDate
- AuditArea
- Auditor
Sub Table:
tblDiscrepancy
- Discrepancy
- CorrectiveAction
- ActualCompletionDate
- VerifiedDate
- Notes
Sub table to Sub Table
tblFollowUp
- FollowUpDate
- AssignedTo
- SpokeWith
- EstimatedCompletionDate
- Notes
Sometimes tasks change hands or are pushed back depending on work load. It would be nice to be able to track something like this.

I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?

I have some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do it?
Thanks,
Josée

I have being playing with ms access but I really don't know much about it or databases in general.I have created a very simple database to gather twitter following/followers data for research purposes.One table (table01) has a field for the "boss" user (=the user who I gather data for), another field for "client" (=bosses followers or friends).Both fields are numeric and contain the users id's.In order to distinguish if the link is follower or friend there is a third field, called type which can be either 1 (=follower) or 2 (=friend).So the data would look like this:
boss - client - type
12345, 67890, 1
12345, 54321, 2
If user with user id 12345 had a follower (type 1) with user id 67890 and a friend with user id 54321...In order to avoid getting duplicate rows I also added a unique identifier which is of the form boss_id-user_id-type.So the above row looks like this:
12345-67890-1, 12345, 67890, 1
12345-54321-2, 12345, 54321, 2
That works just fine.For several reasons I also needed data of the form source - target.So I also made another table (table02) of this form.
67890, 12345
12345, 54321
...
In table 2 you don't need the "type" field since the position of the user id shows the type of relationship.Still, you need a unique identifier in order to avoid duplicates, so I added on with the form: source_id-client_id..So table02 lookes like this
67890-12345, 67890, 12345
12345-54321, 12345, 54321
...
Both tables also have a date/time stamp for each line.As you can see, table01, having also a type field is bigger than table02.The problem is when I try to append data, exactly the same data in both tables.Appending data to table01 is ok, while appending data to table02 (which is smaller, having one less field) takes a really long time, maybe 10 times as long as appending data to table01.To make sure that no query's are causing the problem I have tried first creating temporary tables with the data to be appended, no duplicates, nothing that would cause the database to make extra calculations and used a simple update query with no filters to append data.Still I get the same result, table02 takes a very long time to finish while table01 finishes in no time.

I am currently using Microsoft Access 2010 32bit, and have one database acting as parent, with a second linked database as a client for people to work with, and the parent database has tables imported from Sage V21 via ODBC. I have used the following code as specified in other examples as follows:
Code:
DoCmd.TransferDatabase acImport, "ODBC Database", "ODBC;DSN=MyDNSMachineName;UID=MyUID;PWD=MyPassword;LANGUAGE=us_english;" & "DATABASE=pubs", acTable, "INVOICE", "INVOICE"
one of the tables has 10k records in it, it only transfers 77 records. After manually attempting an import via the ODBC wizard it finally lets me access all 10k records.I wish to have a single button click delete and import fresh tables without worrying if all the data is coming across.Also, when manually adding a table, I am usually asked by the wizard to specify an index, but with the code above, I am not offered that option and the tables come across with no index. I am led to believe that having tables that link to each other without an index is bad, so how do I ensure an index is created?

I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.

I have an Access Table with about 28,000 Automobile dealerships across the country shown. I've joined a new/small phone contact table to this to keep up with our phone contacts with the dealership and followup efforts. When I search/filter on the dealership table all is fine. However when I search/filter on the phone contact table with a few test entries, I get nothing at all. I supposed that after joining the tables, I'd be able to do a search on the field named follow up date and find/filter today's date or other dates and locate which dealerships to contact when the correct date arrives. But nothing.

I have 3 tables.
Table 1: contains staff names and contact numbers
Table 2: contains training above staff have been on or need to go on
Table 3: contains pc and printer asset numbers of above staff
I used a form and entered some new members of staff in table 1. They got their auto numbers etc but when I open table 2 and table 3 those new members are not showing up in those tables. I have checked the relationship status between the 3 tables and the staffID from Table 1 is associated to table 2 and to table 3.
What's stopping the new entries from showing up in tables 2 and 3 ?

I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?

I am working on a database which has two tables used as part of a registration and login process.
I would like a couple of fields from table one to automatically update in table two, once the fields in table one are populated without using an 'on click' event.
The reason I would prefer not to use an onclick is because the completion of the form used to generate the users table does not require any buttons for the data to save.

I have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.
