General :: Linking Fields In Tables
Aug 23, 2013
Im in the process of developing my first database for my bonsai (small trees) collection. So far, ive developed a table of each of the trees I have, with fields such as Species, Where Bought, Cost etc and ultimately a link to a recent photograph (my next challenge). Ill be adding to this as my collection grows (in number and size). To avoid information duplication I have a separate table of care instructions for each species of tree with type, position they favour (eg Hardy/Delicate), watering requirements, wiring advice etc.
I now want to have a field in each of the records in the first table to its particular species care instructions as simple as that, or so I thought. ie for each different pine I want a link to the care guide for pines, and only pines. And preferably in a table format.
I need a one (second table) to many (first table) relationship and have linked them appropriately through primary field (species) and foreign field (care details). I have tried various Controls in the Design View but cannot get the field to show just one care record (ie the one for that particular species of tree). I realize this is possible, as its a common feature of a good database, and have found it being used in the various templates available - but not how they were created. The best Ive got to is using a Combo Box but this shows all of the care details records and in a column view.

I've been using a series of 5 tables to export an XML file using Access's native XML export. In order to keep the XML intact, there are relationships setup to link each sets of elements together via an ID number(link) field in each table.
Access does a great job at exporting, but then we need to rely on another program to delete these link fields that links the tables together so our XML validates. Additionally, we use this program to reorganize some of the XML, as one of our tables puts itself at the end of the XML element and not in the middle where it should be. This is not a problem when I'm dealing with a few hundred records, as the 3rd part program does the trick. The problem is when I have enough data to generate a 30+MB file that my other program chokes on when trying to manipulate the XML.
So my question is...how can I export these 5 tables to XML while omitting the linking member fields and organizing it how it should be? I have examples of code below. How Access Exports it
Code:
<MASTER-RECORDS>
<RECORD-ID-NUMBER>5648743524654</RECORD-ID-NUMBER>
<RECORD-ID-NAME>JOHN SMITH</RECORD-ID-NAME>
<link-for-pseudonyms>123456</<link-for-pseudonyms>
<PLACE>USA</PLACE>
<DAY>MONDAY</DAY>
[Code] .....

I have two different tables. Table1 contains information such as the name of a patient, which is the primary key, date of birth etc (fields that will not change). Table2, linked by the subject id, contains information about tests that they may have gone through. A form has been made using these two tables, in which table1 is that main form, and table2 is a subform. I want to add a field in table2 called "CurrentAge", which will use the date of birth specified in table1, to calculate their current age, and would like it to be displayed in the subform.

I am trying to take the data that is put into a form or report and export it to a certain document in word.
The user will be filling out a Reciept. On the form there will be a to and from box for them to fill out, along with many other options. Once the user enters in all the data required I want them to be able to click a button and it generate onto the attached file, in its perspective fields. Is there a way to match the documents to correspond to my program?

Why is it when I click on the TblCarerdetails and try to open a record with the plus sign I am present with the following error message Enter Parameter value CarerID///The frmCarerRota seems to be working ok, the relationships seem to be ok i.e TblCarers can have many rotas i.e. a different TblRota each week (1 - M)
TblClients can have different TblRotas each week (1 - M).why the tables are not linking correctly, if I click on the TblCarer plus sign.I should see the Rota details and a plus sign. If click on the plus sign, I should see the clients details.Therefore I am assuming that my relationships are not correct, I think I need to add an association table, but where and what fields do I need to add/create.

I have two tables called Hardware and Desk. They both have two fields called ChangeID and Priority.
What I would like to do is set it so that if we change the Priority in a record existing/created in 'Hardware', the Priority of the related record in 'Desk', also changes.
How can I achieve this?

I have two tables that I'm struggling with how to relate to each other. One is tblHardware which contains all the items that we sell. There are no duplicates in this table. The only columns are a part #, description, long description, and cost.
Then I have another table with is tblPackages. These are the packages we sell which pull from tblHardware. This one just has an autonumber, description, and image (image I'll add later and not worried about now).
What I'm struggling with is how to tie these two together because one Package will contain multiple items from Hardware however there are multiple Packages that have the same Hardware items (17" monitor for example).

I am trying to take similar fields from unrelated tables. both fields contain information about the age of my clients. The tables they are in are unrelated, as they are different types of clients, and therefore can not find anyway to relate the tables. I need to come up with a total number of clients at particular age groups. Meaning i need to know how many clients from both tables are between the ages of 8-20, even though the records have no relation. All i need is a count, i dont need to display the records, i dont need to change anything, I just need to know how many.

I have a few fields that are the same across a couple of forms and sub-forms (each form/sub-form being represented by a different table). I would like for data entry into one field to ensure that the data is autofilled into the other. ie if I type 'ENG' into field 1 on form 1, it will autofill the equivalent field in sub-form 2 as 'ENG' so that I do not have to type the same thing twice. These entries are not unique or in any order as it is variable depending on the entry and so they can't be linked as primary keys and foreign keys. So how would I do this? I would like to avoid VBA is possible.

I think what I want is:
1 table(1): record of people & contact details
1 table(2): list of events with check box's with the names of people from the other table
1 report: listing how many events people have attended.
When I add a new person to table 1 I want a field to be added to table 2 in the form of a checkbox, also when I delete this person I want this field to be deleted in table 2.how to make this an automated process.

I have two tables, "Summary" and 'POC Information". In the "POC Information Table I have all my Contacts Information (Name, Title, Phone, Email, etc...) and I am trying to assign 2 POCs to each of my multiple projects located in the "Summary" Table. I am using a Form called "JCIDS Tracker Input Form" as the link. So far I am able to assign one POC by a combo box that lists "Full Name", then it autofills the other information...Phone Number, Email, etc... The problem come into being when I want to assign a second POC to the same Project...I can assign a name, but it won't correctly autofill the rest of the information...it just autofills in the information from the first POC that was selected.

The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?

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?)

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.

I am doing a project where we are collecting home owner data and information on all the dogs in the household. The data for homeowner has an autonumber primary key because no field is unique or has been consistently collected. I am struggling to link the data for the dogs to the owners because an autonumber primary key will not work since not all homes have dogs. I need to have this set up so that people who are not tech savvy can look up each homeowner (or dog) and get the dog (or home owner) information. And to make things even more fun we need up to 15 potential dogs per household each of whom will have 18 different pieces of data collected.
It looks a little like this (and you can see my not matching ID issue):
Homeowner table
ID First Name Last Name...........Total Dogs
1 Max Maximus 5
2 Min Minimus 0
3 Mus Musculus 1
Dogs 1-5 table
ID Date Dog 1 Name Dog 2 Name .......Dog 5 Name
1 (Max's) 4/11/14 Bobby Billy Betty
2 (Mus's) 4/11/14 Jojo
Min will have no dog records at all, just home information.how to link the dog's to the homeowners .

I have been asked to design a database to replace our old excel sheet to log one of our customers server builds. It a four noded system and i require a seperate log for each node serial models of parts etc, qa checks.
I intitial started by just using one table but forgot the limit was 255 rows, i need about 600 - 700. So my plan is now to transfer to indivial table for each node. Then, a general table named Main for all my other details.
Although this seems simple, i now have the annoying task of being able to link them all together and produce a single PDF file to send to our customer whilst only entering our system serial number once to produce this.
My basic understanding will be to create a System Serial Number field in each table a link it via relationships, but if i produce a report with everything i need would it input my details for all four nodes? If so how would i set this up?
I will be splitting the database once completed and then making a ACCDE file for my techs to use.

I am trying to create a table for an assignment on normalization. It is similar to the problem here : http://pubs.logicalexpressions.com/Pub0009/LPMArticle.asp?ID=88
I am trying to make it so that if a name appears in the Spouse, Child 1,2 or 3 column it will automatically appear in a dependants database with the EmpID and the Name of the Dependants, as separate objects so that the EmpID could be repeated. I have scoured info and I can't seem to make it work. Any help would be appreciated.

Good morning everyone:cool:
I was wondering if there is a way to link one field from a table to another table?
I have a main table that all of the data goes to and then a second table that the completed data goes to. I have made a query to show info from the main table and one field from the second table and it will only pull the info that is on both tables...i want it to tell me the info that is not on the second table:confused:
Sorry if this is confusing, but any help would be appreciated...thank you

Hi everyone,
Having a little problem, have searched the forums but have not been able to find an answer.
I have a single db with 3 tables, artist, gallery and arts.
The main form should show the work details for each artist, i.e. each piece of art they have done. The problem I have is I think I have a link or relationship problem as when I try to create a new record in the arts table, I have a combo box which populates the artist name and gallery name and it should then store these details in the arts table along with the rest of the details I enter but it doesn't.
Each table has an autonumber and there is a one-to-one relationship from arts to artist and arts to gallery.
Can anyone help?

I would like to link 2 fields in a form. If I select data within one field with drop down list it should automatically bring up a name within the 2nd field. How would I be able to do this?
I've managed to lind the subforms to this drop down list which works brilliantly but this is a field within a form that I don't know how to link.

Ok. I have used access before to hold data but have always accessed and used it via asp. I have never actually tried to use the access forms and queries! But for a current project i am having to use it.
So far its been fairly simple but im stuck on one point. I have one table that holds user info and has a foreign key from another table. On my form i want the user to be able to lookup the foreign keyes available. Only i want the lookup to show the description field in the other table not the unique id (primary key) but when they slect the relevant row its obviously need to record the primary key of the other table in the foreign key field in my user info table.
How can this be done? Im not sure if i explained this very well. If anyones unsure what i mean please ask my to clarify.
