Table Relationships
Sep 22, 2006
Hello all,
I have tables related by key fields. Is there a way to enter data into one table and have the key fields of the related table automatically enter into the key field of the related table?
Also, can you make custom drop down menus in a field? For instance, I have field that I would like to have a text in, there are only three values that are needed but spelling is important so I would just like to pull a list down to enter the data.
Thanks for any help!

I am trying to put together a sales/purchase/stock control/accounting program using Access. I have put together a number of tables that I feel will be required and now I'm trying to set the relationships between them. The primary end document to be printed will be a Sales Order and a Purchase Order, likely generated from the reports module, so I have a table called Purchase Order and another called Sales Orders, related to Purchase Orders will be a table called Suppliers and another called Customers will be related to Sales Orders. Another table is called products.
For the Purchase Orders table, do I only add fields that are the primary key from the Suppliers table in order to list the full customer name and address stored only in Suppliers table. Would the supplier table be the parent and the Purchase Order the child ?

I have setup a number of tables for a booking system. The tables are as follow:
tblCustomers
tblBookings
tblRegularCustomers
tblRegularBookings
When a booking is made for just any time, it is in the tblBookings table. Regular bookings for example, every week, are put in the tblRegularBookings. In each of these tables, a booking cannot be made for the same date and time period. I am wanting to link the tables, so that when a normal booking is made in the one table, it cannot be the same date and time period as a regular booking as well.
The fields in each are as follow:
tblBookings:
Booking ID
Customer ID (linked to tblCustomers)
Date for Booking *
Time Period *
Weddings/Birthdays (yes/no)
Extension (yes/no)
Cost
tblRegularBookings
Regular Booking ID
RegCust ID
Date For *
Time Period *
Extension
Cost
What should i link to allow me to not create a normal booking on the same date as a regular?
Thanks

Here are my relationships for my 5 tables I created. My database is something that a turn key automotive performance shop would use. Tell me if my relationships are correct and what I need to do. I think I got a good start but I am not sure on a few things. Also what do I need to do for my validation and look up tables. Any help on that would be great. Thanks.

I have restructed my original tables into 3NF and added relationships. But I think I am missing a few more items to go on to next step. Help me, please! I am putting together an automated Time Card Entry Database based on a timesheet and other reports already existed in Excel.
I have the following fields on this form as follows:
1. Week Ending: automatically populates with "mm/dd/yyyy" date format from tblPayrollSchedule. This field will insert the correct pay period with comparing against today's date.
2. Employee Number: combo box that will populate next fields (1. Employee Last Name; 2. Employee First Name) after user select correct Employee Number.
3. Employee Last Name: automatically populates when Employee Number is selected.
4. Employee First Name: automatically populates when Employee Number is selected.
5. Acct Id: combo box containing a list of labor description that has associated fields as follows.
6. Description: Text Box will populate after selecting Acct Id.
7. Cost Center: Text Box will populate after selecting Acct Id.
8. Acct: Text Box will populate after selecting Acct Id.
9. Category: Text Box will populate after selecting Acct Id.
10 Pay Type Id: combo box that will populate Pay Type.
10. Pay Type: automatically populates when Pay Type Id is selected.
11. Allocation: Free form, to type comments.
12. Days of Week: Sat, Sun, Mon, Tue, Wed, Thu, Fri
13. Total Wk Hrs: total hours for the week for per line of Acct Id.
Here are my tables:
1. tblEmployees:
1) pkeyEmployeeId = AutoNumber
2) strLastName = Text
3) intStaffNumber = Number
4) fkeyEmployeeTypeId = Number
2. tblEmployeeType:
1) pkeyEmployeeTypeId = AutoNumber
2) strEmployeeClass = Text
3) strEmployeeType = Text
3. tblAccounts:
1) pkeyAcctId = AutoNumber
2) intCostCenter = Number
3) intAcctNo = Number
4) intCategory = Text
5) strAcctName = Text
6) strAcctDescription = Text
3. tblPayType:
1) pkeyPayTypeId = AutoNumber
2) strPayType = Text
3) strDescription = Text
4. tblPayroll Schedule:
1) pkeyPayrollScheduleId = AutoNumber
2) intPayPeriodId = Number
3) dtmPayStartDate = Date/Time
4) dtmPayEndDate = Date/Time
5) dtmCheckDate = Date/Time
5. tblTimecard:
1) pkeyTimecardId = AutoNumber
2) intStaffNumber = Number
3) fkeyPayPeriodId = Number
6. tblTimecardHours:
1) pkeyTimecardDetailId = AutoNumber
2) fkeyTimecardId = Number
3) fkeyAcctId = Number
4) fkeyPayTypeId = Number
5) strAllocation = Text
6) intSat = Number
7) intSun = Number
8) intMon = Number
9) intTue = Number
10) intWed = Number
11) intThu = Number
12) intFri = Number
Here is the layout of my form in this order:
1. Pay Period Id
2. Week Ending
3. Employee Number
4. Employee Last Name
5. Employee First Name
6. Acct Id
7. Description
8. Cost Center
9. Acct
10. Category
11. Pay Type Id
12. Pay Type
13. Allocation
14. SAT
15. SUN
16. MON
17. TUE
18. WED
19. THU
20. FRI
18. Wk Hrs
Question 1: Please review table relationships to see if I overlooked any tables that can be broken down or named its column differently?
Question 2: I have restructured these tables into 3NF, please see my previous posts under AccessRookie (although before 3/2005, someone used this ID).
Question 3: what code do I need to automatically populate "Week Ending" field with the correct "CheckDate" that will compare against today's date and insert into "Week Ending" field? Currently, user selects from Combo Box(Pay Period Id) then it populates Text Box(Week Ending).
Question 4: how come "tblTimecardHours.fkeyTimecardId" field is not populating? I think it is my table relationship: tblTimecard & tblTimecardHours.
Question 5: what code do I need for "Wk Hrs" on subfrmTimeEntry, this column needs to sum these columns: SAT, SUN, MON, TUE, WED, THU, FRI).
No need to store total since it is only need to display in data entry form (subform) and printing report.
I need your assistance since sometimes, it just takes another pair of eyes to review another peers' work. It's been ages since I've done any development from scratch. Help!!! Is there any way, I can attach my zipped database? It is 217KB zipped but this site only allow 100KB attachments.
Sincerely,
AccessRookie =)

Ok im extremely new to this whole Access thing so I have several questions. First, let me give you an idea of what I am attempting: I am a member of a committee and we are involved in multiple projects. Each person is either inactive (working on no projects) or active (working on 1 or more projects). I want to set up a table that lists the member names, contact info, and which project(s) they are currently working on. I set up the basic table (not sure if its set up correctly or not though) but since some people are on more than one project, how do i make it so i can enter multiple values for the "Current Project" field? Also, I would like to make another table that lists Project Names, members (the members that are working on each specific project), and project description. How do I set it up so that under members (on the project table), it will gather the info from Member table (the one with contact info and such) and automatically list which members are working on each project? Also, There is one Leader per project and the rest working on it are just normal members. Can anyone suggest a good way to display who is leader on each project?
if this is confusing, just ask and i'll try to clarify for you
thanks, TRC

I have 2 tables. One is JOB TRACKING and has all the information about a certain job and all the trades involved. The other is a table of email address for the managers of each of the trades. I have them connected (with relationships) so the trades match up.
There is a form that I fill out each time a new job comes in and I check off the trades involved on that form. Is there a way for that form to pick up the email addresses of the managers of the trades checked off? So then I can create a button some how to send an email to them containing that particular form...
thanks!!

I'm using Access 2003. When I open the relationship window, one table linked to my main data table appears six times - the name is the same but with the addition of a number 1 -5. I can delete the five spare ones and drag a relationship to the main table but it keeps dissapearing.When I try to change the primary key in this table, it tells me that there is a relationship established which I must break - unfortunately, I can't see any relationship between the two tables in the relationship window. Any ideas?

Hi. I've been trying to create a link between two different tables which i've put on the Relationships screen. Any type of link made between RepairScheduleID on the one table and RepairScheduleID on the other table disappear when I reopen the database after closing access. This happens if I save, if i don't save it requests me to save then doesn't store the changes anyway.
Ideas? What on earth is wrong?

Hey
I was wondering that is it possible that is in one field I select a certain name, say a type of product and that in another field will automatically display the price of that product based on another table.
Thanks

I have a database which has been running well for four years. There are four tables that are linked from one to another in a one-to-many relationship, i.e., Table1 to Table2 to Table3 to Table4. We recently had a power failure and our network went down. Now the relationship between Table2 and Table3 is broken. When I try to rejoin them using the Relationship View, Access tells me that the relationship between the tables is "Indeterminate". I have run queries testing for unmatched records between all of the tables and the data appears to be fine.
My only guess at this point is that the structure of one of the tables is corrupted. The problem is that each of the tables has an autonumber field. If I build a new table structure, and append my old data, isn't that going to renumber all of the records?
I have run a compact and repair on the database and that didn't help. I have made copies of the tables and tried to use them in the relationships. The copies don't work either. Other than not being able to link the two tables, everything is working fine.
Does anyone have any ideas?
Thanks,
Cherry

Hi all! Here is what I want to do, and what I have done so far:
I have one table called "AUTOS" This is a table imported from pc file, and tweaked to make it work well in Access. I learned alot doing this, and now have workable forms, queries, and reports being generated on this table. I learned on here not to let my users "work" with the table, only through forms. So that all works very nicely!
Here is the next step. First a simple background: We are a Used car dealer. Table "AUTOS" contains rows, each one consisting of many Fields. The main one being "Stock NO". Then all the remaining fields are vehicle info (many fields, but all relating to the vehicle type etc), cost, sales price, etc.
What I want to do is create a new table, called RECONDITIONING. In this table I want to store everything done to a vehicle after purchase. For example, if we purchase a vehicle, then change the oil, put on new tires, and detail it, I want these items in the reconditioning table. But I want them to remain linked to the "correct" stock number in the main table.
I believe I have done this, by doing this: I created a second table called reconditioning. Added the fields I wanted, the first one being "Stock NO". I made "Stock NO" in the main table autos the primary key, and then opened relationships, and linked the reconditioning table to the main table via that field.
It appears to have done what I wanted too, because if I open the reconditioning table, and type in a vehicles stock no, then the reconditioning info, then go back to the main table, there is now a + next to the row. If I click this plus, a box drops down with each item I added to the reconditioning table. So far so good!
Here is the main question: Now that I have this info in what seems like the proper fashion, how do I work with it?
I need to create a form, containing elements from EACH table. The design I have in mind is like this:
Across the top, I want vehicle info:
Stock No Year Make Model Date In Cost
5922 1994 Ford Focus 1/1/05 1000.00
Then under that, I want a "table" in a form, which pulls from my "reconditioning" table, listing each item that has a stock No that matches the one on that record:
5922 Replaced Windsheild Wipers 1/8/05 20.00
5922 Tuned Up 1/10/05 75.00
Ok, now, I want to allow my users to add to that on this form, to type in new entrys. I think I got the idea how to do that, but suggestions are welcome. Now, on this form, I want at the bottom, the following:
Vehicle Notes: (Just a text field for "notes" on a particular vehicle)
Total Reconditioning cost: (this is a field on the FIRST table, AUTOS, that I want to calculate by adding the total from the list above, IE in this case, 95.00)
Total_ACV: This is a field from the first table as well, which I want to calculate using (Vehicle cost: Which is in the first table)+(Total Reconditioning Cost: which is above)
Like I said, I think I have the table layout and design correct, I am just not sure of how to work with values in linked tables like I have done, and I am not sure get the right info in my list on the form, then add the totals properly.
Any suggestions are appreciated!
Bill

Hi Guys, thought i would pick your brains to try and help me figure out how to build this database. Any help would be very much appreciated as this one is making my head spin.
Brief::
I need to create a database that will hold information about our suppliers and the products that they stock and make.
One supplier can have a number of contacts that we speak to.
The supplier produces a number of different products.
Each of the suppliers stock certain items in certain sizes and weights and make the remainder of their stock to order, so each supplier has a number of different supply options. So in addition to the multiple supply options their are multiple sizes & weights, as well as multiple qualities.
dont know if this helps people to understand buit the products we are talking about is paper (sheets or paper & reels of paper)
example.
Joe BLoggs (Supplier) has 3 sales members (Louise, Maggie, Sue) this supplier holds some sheets and some reels in stock (Stock Sheets, Stock Reels) but they also make sheets of any size and weight between a certain range as well as reels (Bespoke Reels, Bespoke Sheets). These sheets and reels can be of different qualities (gloss, silk, offset). These different qualities can have a number of different grades (Manhattan, Triumph, Charter) and will be available in a number of different weights (70gsm, 115gsm, 150gsm).
The idea behind creating the database is to allow the sales team to query the database to find a supplier that can match the customers criteria.
I have created the following database tables
tblMainDetails
AccNo (PK)
SupplierName
Address1
Address2
Address3
Address4
PostCode
Tel
Fax
Web
Email
tblContacts
ContactID (PK)
FirstName
LastName
Tel
Email
tblStockingOptions
OptionID (PK)
BespokeSheets
BespokeReels
StockSheets
StockReels
TblQualities
QualityID (PK)
PaperQuality
tblWeights
WeightID (PK)
Gsm
tblPaperInfo
PaperID (PK)
SupplierPaperName
OurName
PaperInfo
Do these tables look aabout right???? Now comes the bit thats making my head spin Relations, can someone please give me some advice on this.

Hi all,
I've just gone into the Relationships diagram and discovered that one of my tables is off the page! (see picture).
Dont know how this happened although I have noticed that Access has a habit of moving the table around the diagram after being in Design mode.
Anyone else had this problem? How do I get the table back onto the page?
Many thanks in advance...

hey.. I’m a complete newbie at designing tables and relationships, so pls bear with me..
Im trying to construct a db that records all the details for an importing company.
Background: the company imports goods (shipments conducted by Freight Company), from a Supplier, in Containers, and then arranges Delivery of the goods (delivery completed by Haulier Company). Customs requirements must also be met.
so far these are the tables I have:
tblShipping
tblContainer
tblDelivery
tblCustoms
tblSupplier
tblFreightComp
tblHaulierComp
Here are the relationships:
1)Each shipment (tblShipping) can have many Containers, but each container can only have one shipment (tblShipping) : 1:M
2)Each shipment (tblShipping) can only have one Supplier (tblSupplier), but each Supplier can have many shipments (tblShipping): 1:M
3)Each shipment (tblShipping) can only have one Freight Company (tblFreightComp), but each Freight Company can have many shipments (tblShipping): 1:M
4)Each shipment (tblShipping) can only have one Haulier (tblHaulier), but each Haulier can have many shipments (tblShipping): 1:M
5)Each Container can only have one Delivery (tblDelivery), but each delivery can have many containers: 1:M
6)Each Container can only have one Customs Check (tblCustoms), but each Customs Check can have many containers: 1:M
7)Each Delivery can only have one Haulier, but each Haulier can have many deliveries: 1: M
These are the most important relationships (not all of them).
Where I’m getting confused is whether or not I should (or need to) create additional junction tables? If someone could have a look at the attached screenshot (of my tables with fields and pk's - but no relationships defined yet) and advise, I’d really appreciate it!
Also, im having some major probs with my variables and forms… the P/C No in the Shipping Table is the most important value here. This number is used repeatedly throughout the process. Problem I’m having is that this number needs to be alphanumeric, and also get passed to each other table (hence P/C No as a fk in each other table). How can I do this? Ive been playing around with loads of diff relationships but with no luck. I ideally need this alphanumeric number, when entered in the first form, to be ‘sent’ to other forms, as I chose. How can I do this?
Any help is really appreciated!
Thanks

I am trying to define a relationship between tables. The relationship is one-to-many with forcing referential integrity. When I try to define it, I get the dabaase engine error:
"The database engine couldn't lock the table, because it is already in use by another person or process"
I am sure that the database is not opened by anyone else, it is 100% local, no other instance of Access is running, and there was no *.ldb file... What can be the problem?

I have a table of courses our university offers along with what restrictions are placed on them. The table has the Course ID as the primary key, and then the field is Restriction. For the sake of the example, I'll use the course names instead of their ID #s:
Course Name Restriction
Acting II Acting I
Acting II Fundamentals of Acting
Acting II No Freshmen
How can I incorporate the following logic into this table.You must take either Acting I OR Fundamentals of Acting before taking Acting II AND you must not be a freshman.this table is in a "one to many" relationship with the course inventory table. One course may be associated with many restrictions.

I am trying to create a database that will allow the user to Create new projects and assign them with a contact and organisation.
In other words, there should be Organisations that can have multiple contacts linked to it and each contact can have multiple conversations attached to it.
An organisation can also have multiple Projects attached to it whioch are in turn attached to a contact.
Can anyone help me with the table setup and relationships?
Right now I have four tables:
tblNotes
tblContact
tblOrganisation
tblProject
tblNotes with a foreign key (ContactID) is linked to primary key (ContactID)in tblContact.
tblContact with the foreign key (OrgID) is linked to primary key (OrgID) in the table tblOrganisation.
tblOrganisation with the foreign key (ProjectID) is linked to primary key (ProjectID) in the table tblProject
I can't seem to get the tables to link together for example I cannot get my tblOrganisation to see many projects asrequired.
Can anyone help wuth a suggested table layout and relationships?
Many Thanks

Hi, I am currently stuck on making a working one to many table relationship, I will post what I have so far, what I am stuck on is forming a proper working relationship.
tblCustomers
CustomerID
Name
Address(street)
City
Region
PostCode
Telephone
Discount %
tblOrders
OrderID
ProductID
Description
Qty
UnitPrice
tblProduct
ProductID
Description
Room
Finish
UnitPrice
Stock Qty
The desired output is a working order form, that when, for example you enter the product ID into the appropriate field automatically brings the rest of the product fileds such as description and unit price. And when the customer ID is put into the appropriate field all of the relative customer info is shown.
I am new to access and I apologise if my post is unclear or incomplete, any input is appreciated.
Thanks in advance.
