Forms :: Form To Display Information From Junction Table?
Feb 3, 2014
I've established a many to many relationship using a junction table.
So I have 3 tables (A for "materials", B for "batches", and J for "junction")
Form A is linked to table A, and contains a subtable linked to a query from table J. This allows me to input materials into table A and then list all of the batches it may be used in that are in table B. I successfully got this to input all the batches and materials combinations in table J.
Now on form B, which is linked to table B, displays the batch information, with the subtable J.
My problem, is that only the materials primary key is showing, not the other information that should be linked from table A.
trying to understand how to create a form with a Junction table. This design will allow a book to have more than 1 author.
Author table Author ID AuthorName
AuthorID table (Junction table) AuthorFK BookFK
Book Table BookID Book Name
Author table has a 1 to many relationship with AuthorID table and Book table has a 1 to many relationship with AuthorID table. Now how do you create the forms? Do I need a main form FrmAuthor , subform FrmBook and a frmAuthorID
I have a simple database, consisting of two tables and one form. I'd like the form to display information mainly from the first table (table 1). For this, I have used the Form Wizard, which works well and displays as it should. My problem comes when trying to display data from table 2, without using the Form Wizard.
I have a simple field called 'Number' in 'Table 2'. I'd like this value displayed in a text box along with table 1's data. I've tried using the expression builder, which gives me something along the lines of:
[tbl_Table 2]![Number]
But this is displayed as:
#NAME
...when I open the form. Could anyone explain how I do this correctly please? All I'm trying to do is display data from other tables in the form.
What I would like to do is create a list box that will only display the information from another form that is related to the current form.So I have a form call Equipment Catalog and that form is related to Equipment features 1 to M relationship and the Equipment Features is related to a Features form M to 1.
So what I want to do is display all the related equipment features in a listbox that is related to the current PK of that form.So if there is only one feature on one form the list box will only display that one item however is there is 6 features on another it will display all 6.I have been trying SQL and Queries but I still can't get it to work.
I am trying to create a main form that selects a series of values allowing the user to enter new data or edit current data (using other forms). I have a series of cascading combo boxes that populate accordingly and become visible after update. I can successfully create the series and add new data and edit data as in my code.
How to populate the junction table from the forms so for example when editing or adding a new site it not only populates the tblSites and the tblSitesContacts it also populates the tblClientSitesJunction with values from the frmSites and also cmbClients. If I use the wizard and try and add values from all 3 tables to form it doesn't work and I am not sure how to add the ClientID and SiteID manually to frmSites.
I would like to use a listbox set to multiselect to add records to a junction table. I've been using code to accomplish this with checkboxes (love how it looks and works) but after moving my tables to Office 365 as the backend, linkedto a local frontend, sql does not like this particular set up, and I do not have the time or knowledge to sort out why. So what I need is a step by step to look at the many, in this case possible roles a contact can have, and choose one or more, which then creates a record in the junction table with the contact id and role id.
I would prefer to not use a combobox on a continuous form because every time a user goes to select roles he would have to scroll through all the choices for each separate role.
I've created a query called "JobHistoryQuery" and a form called "JobHistoryMultiForm", this displays all Jobs related to an Asset and all the information about that job. There are some fields (BilledMonth, BilledYear, BilledValue, Parts Required, PartsUsed), however, that I would only like to see if I need to see them (as there is quite a lot of information on the form and ideally, I'd like to be able to see the key information from each job from that asset with ease). What I would like is to create a button that says "Billing" and "Parts" for each job and it brings up a pop up window displaying that information.
I am trying to get a form to display certain information based on the data in another box. I have to input some exam results and want to assign a level to them. So, if they score < 13, the result would read "Below Entry 3" if between 13 and 21 "Entry 3" etc If this was a spreadsheet I would use an if function, but I am not sure that I can do this here
Is there a way to display/hide the information on a subform using a checkbox?So, when the checkbox is checked, the fields are blank but when the checkbox is unchecked, the information displays?
I would like to first state that I am new to Access and trying my best to pick up on skills, so pardon if my questions seemed redundant or illogical. I'm trying to create a sort of quick-access/all-in-one Access form that..
1) Displays contact details stored in an excel sheet 2) Opens application on click 3) etc..
I am able to get pointer 2 sorted out, however am having trouble with pointer 1.
I have the contact details stored in an excel sheet, of which I am aware of how to import it into Access. However, my idea was to have a tab where firstly there are 4 buttons, say buttonA to buttonD.
I want it to perform an action such that when i click buttonA, 5 other buttons (say button1 to button5) appear on the right of the 4 existing buttons.
If I press buttonB however, button6 to button10 will appear and replace the button1 to button5 at the same spot.
After which, if I press button1 etc, there will be a field where contact details are displayed (name/number/etc) and it switches as I press different buttons.
I have a searchable form that display information on agreements other companies have with us. If a company requests an inspection we have 30 days to go out and complete it.
I am trying to create a message box that will display all inspections that are due within 5 days when the form loads. No luck so far, only broken dreams.
Is it possible for message boxes to use expressions and display information that fits the criteria?
I use Me.Filter & Me.Filteron to filter the data from the table to display in the form, i used this in On Open event & This is working fine.
But in the filtered form when the user right click and filter some value and unfilter the search (in the bottom of the form next to search (Navigation Button) ) then this shows all the data from the table i.e its not taking the on open filter condition.
In my form (source tblJobs) i input a contract number from tblContracts. but i would also like it to show the contract address when the contract number is entered. Both fields belong to tblContracts but i only wish to enter the contract number, the address will just be used as a reference as it isnt something i would have to enter again.
So for example
112 - Main Road
If i enter 122 in my ContractNo field i would like it to show the contract address for that specific contract.
I am trying to set up a Real Estate database, and can't get the Relationships to work. I have three tables:
House Listings Farm Listings Clients
Clients can have properties in both House and Farm Listings Tables, so I need a Junction Table (or do I need more than one?)
The Primary Key fields of House Listings Table (HouseID) and Farm Listings Table (FarmID), become a composite Primary key in the Junction table. Is this correct?
Both the House Listings Table and the Farm Listings Tables have a field for Client ID. Is this causing me problems, as I can get the Farm and Clients Queries to work, but not any queries with the House Listings. As this is my first attempt at creating a database with many-to-many relationships, please explain in simple terms what I am doing wrong.
I'm working in the petro-chem and industrial service industries now, and am finding there are relationships I haven't had much exposure to in the past.
Can someone please help me with constructing the tables and relationships needed here?
This is something I should probably know, yet I've never created junction tables which must take into account nested data. I have created a relationship which works, but I feel it could be done in a simpler fashion.
By the way, I cannot find Pat Hartman's many-to-many sample db. It is either missing, or the restrictions on word length in Search just aren't letting me find it.
Table: WorkOrder is the primary table I'm working with. I need to store 4 pieces of information for every WorkOrderID, two of which have subs.
I’m having trouble defining Relationships I’m thinking I need a “Junction” Table and I have tried looking at the Orders.mdb but it hasn’t helped (I’m sure I’m just missing something) I just don’t see how it works. If at all possible please don’t just give the info try to help me understand so I can get the answer myself. Here is what I have: Far table: FarNumID (PK) > autonumber FarNumber > Text “224-10C” FarTitle> Text
FarParagraph table: FarParaID (PK) > autonumber FarNumID > Number FarParaTitle > Text FarParaText > Text
AC table: ACNumID (PK) > autonumber ACNumber > Text ACTitle> Text
ACParagraph table: ACParaID (PK) > autonumber ACNumID > Number ACParaTitle > Text ACParaText > Text
1. Each FarNumber can have only 1 FarTitle 1:1 Each FarNumber can have many FarParaTitles 1:Many Each FarNumber can have many FarParaText 1:Many 2. Each FarTitle can have many FarParaTitle 1:Many Each FarTitle can have many FarParaText 1:Many 3. Each FarParaTitle and have only 1 FarparaText 1:1
All I ever seem to do is sit about trying to figure this out and then give up and ask for help :(
I have three tables.
One for contacts One for groups (groups like people attending meeting a, b c) and a junction table as the top two create a many to many relationship.. one person can be part of multiple groups, and a group can have multiple members.
In the contacts table my primary key is an auto number, and is contactsID I also have some contact details, and a groupID field
In the group table my primary key is GroupID and is an auto number, it also have group name, and description
in the junction table I have a primary key, then GroupID, and ContactsID which are also set at primary keys and are set with the same values as the same named primary keys in the relavant tables (I beleive this defines them as foreign keys... i hope so anyway!)
I have the relationships set up as a one to may relationship from contacts to junction and groups to junction, contacts linking from ContactID to ContactID in each table, likewise with the Group table.
However, when I try to put everything into a main form for contacts,with a subform for groups, all I am getting is the autonumber... which isn't much good for my end user..... :( How do I solve this?
I'm trying to add records to a junction table based on additional record added to one table via form in the many to many relationship. Junction table = ClientAssociation Main table = ClientMain (qry_NewClientNullAssociation identifies new record added) Many to many table = Associations
I'm trying to do this upon clicking a command button that then opens ClientAssociation based on Client_ID. Then allows user to select mutliple associations (Asoc_ID) for Client_ID.
Here's what I have - I'm new at this...
Private Sub ClickAssociations_Click() On Error GoTo Err_ClickAssociations_Click
'Open recordset with new client records Dim db As Database Set db = CurrentDb Dim recClient As DAO.Recordset Dim strClientID As String
Set recClient = db.OpenRecordset("qry_NewClientNullAssociation", dbOpenDynaset) 'Loop through new client ids Do While Not recClient.EOF strClientID = ClientMain.Client_ID
Dim recAsoc As DAO.Recordset Dim strAsocID As String
Set recAsoc = db.OpenRecordset("Association", dbOpenDynaset) 'Loop through asoc ids Do While Not recAsoc.EOF strAsocID = Asoc_ID
'Open junction table and update records Dim recClientAsoc As DAO.Recordset
Set recClientAsoc = db.OpenRecordset("ClientAssociation", dbOpenDynaset) With recClientAsoc .AddNew !Client_ID = strClientID !Asoc_ID = strAsocID !CheckBox = False .Update End With
recAsoc.MoveNext Loop
recClient.MoveNext Loop
Dim stDocName As String Dim stLinkCriteria As String
I just wanted to run this by some experts before I go mucking around in my db. Basically, I am creating a data entry form to populate with information about car parts, and the vehicles they apply to. This is what I am working with:
I am trying to build a form that will allow me to enter new part numbers and descriptions into the table, and then have the user select (through a listbox?) all the vehicles the parts apply to. Is there a way to populate the junction table with each combination of partID and ModelID automatically? NOTE: tblModels is already populated with data.
I am assuming there would be a way to do this... A query of the junction table (and tblModels?) as the recordsource for the form, and then a subform with the tblParts as its recordsource?
I would have posted this in the massive thread I have going already... but I thought it might be nice to give Craig and Adam a break from helping me :o
Hi :) I have solved a m:n relationship by adding a junction table. The composite primary key in the junction table is made up of primary keys from the other two tables, and both of theses primary keys are set to autonumber.
My question is this: Is it correct to set both parts f the composite key in he junction table to number rather than autonumber? I was thinking that since autonumber should be set only once, the junction table should just take on what ever value there is in the primary keys of the other two tables.
I have attached a screenshot of the relationships in (a section of) a database I am working on. Would anyone please be willing to view it and offer any suggestions as to whether is fully normalized or not? Here is the description:
An account [table, Account] consists of some money. That money is split-up and invested into several different places. The funds that are available as choices are in Fund; the funds that are chosen are in InvestmentInstance. Different, unaffiliated accounts can invest in the same fund. I would like to keep track of when an account begins to invest in a fund and when it stops investing there (“InceptionDate” and “CloseDate”). The generic, account-independent performance of a fund is kept in Price, where the values come from Yahoo! Finance or something like that. Similar to Price, MarketValue stores the dollar-amount of an investment, specific to an account.
I think I have most of it set OK, but my main concern is about the relationship between InvestmentInstance and MarketValue. As the picture shows, I use InvestmentInstance’s “Id”* as the “one” in the one-to-many relationship, but “Id” is not a primary key. To get it to work, it was necessary to set the Index option to, “Yes (No Duplicates),” so that it was a unique index. Is this a bad practice? Should I just include “Id” as part of the compound primary key? I didn’t think making it part of the compound key was a good idea because then it would defeat the purpose of having “FundId” and “AccountId” control the uniqueness of records. Am I missing something important?
In other words, how can I correctly create a one-to-many relationship that begins in a juntion table (InvestmentInstance) and connects to a new table that was not involved in the normalized many-to-many relationship (MarketValue)?
Thank you!
* I know many like to include the table name in the ID, like, “InvestmentInstanceId,” and it is only my preference to keep it just as “Id” for a local key for simplicity, but add the table name when it becomes a foreign key. I feel “Id” is good enough for my purposes and it’s table location is usually clear from the context.
Products 1-M ORDER DETAILS M-1 ORDERS M-1 CUSTOMERS
I have ORDER DETAILS set as a junction table so that many products can be recorded within one order. All is good apart from when i go into ORDERS and create a new order. I click the subform which links to the ORDERDETAILS. I then pick a product number(look up from products table). The problem is this: In the ORDER DETAILS I want to display the unit price of this product simply by picking the product id.
Eventually this would form the basis of an order form where I can pick Product Id and have it display unit price.
Any ideas on this one, I'm sure its quite simple!!
