Can A One-to-many Relationship Be Restricted?
Jan 26, 2006Is it possible to restrict a one-to-many relationship so that the many side could be restricted to say 4 records? For example a student can take four courses (no less, no more)

Aug 23, 2005Hi,
Im copying information from Excel to Acces. As I enter the information in fields in Access, this goes just fine. The problem is that sometimes I have to change the information I put in. So for example I first copied 10 record(cells), but now I discover that I have 20 records/cells. But Access refuses to let me enter more than ten. Does anywbody know why it does this and how I can fix it?
Thank u,

Combo Restricted Selection
Mar 8, 2005Hello,
I have Customers recorded and a number of addresses associated with each customer.
They are in two tables linked by CustomerID and are shown in forms as frmCustomers & subfrmCustomerAddresses.
From frmCustomers, I open another form which records the orders maid by that customer. What I would like on this form is to select the customer address to be used for the order.
I can build a combo, but this shows all addresses on the database. What I would like for the combo to show only the addresses for that customer only.
I do not want two combos, one which selects the customer and then another which shows the addresses. This is not very user friendly to ask for the customer again. I would like one combo to show addresses for the customer on the form.
I would be grateful for any guidance on how I can achieve this.
Thank you.
Wizards Do Not Work Under XP For Users With Restricted Security
Jan 26, 2006The problem occurs on a WinXP machine with Access 97.
When Access is run as a Power User everything works fine but when it runs under a user account that is a standard "User" non of the wizards function properly.
By changing some file permissions I can get the control, form and report wizards to work but the Import Data wizard still fails.
I'm sure this is a permissions issue and can be fixed by changing the security settings for some registry keys or files, but have no idea which ones.
Thanks in advance for any help.

Form Doesn't Filter On Load If User Has Restricted Access
Jul 27, 2012I have a report that has a link to open a a form "ProjectDetailsActive" to a specific record ID from the report. It works.
I have 3 subsets of users who have restricted access to the form "Project Details Active". By that I mean that when they open this form, it hides and rearranges some tabs, and disables certain controls. If a user from one of these 3 subsets tries to open the link to a specific record in the form, it does not work. The form opens to the first record available instead of the selected record. This is only a problem for these 3 user groups. For users who do not fall into these 3 groups, the filter works.
This is the only code in the form that does the restriction, but I don't know where the process is going wrong.
Code:
Private Sub Form_Current()
LoadBudgetPage
CancelRsn.Enabled = False
'detect number of line items for current project
Me.lblOrderCount.Caption = GetNumRecords & " line items for this project."

General :: Subform Combo Box Restricted By Form Combo Box
Mar 28, 2014I'm an Access newbie and I'm having trouble restricting a combo box on a subform based on the selection of the combo box on the form.The combo box (Combo1) on the main form (FrmOrganisation) gives a list of companies, I want the combo box (Combo2) in the subform (SbFrmEmployees) to list people only from that company. I then have a subform within that subform that displays information about the employee.

Jan 14, 2006Hi All,
I am new to access and this forum, so hello all.
I am trying to build a database to keep records of my bird sightings. As you might have surmised; I am a birder.
I have come to a holt on creating a complex relationship between the Bird Entry From and the table that contains a list of British birds.
In Bird Entry From two of the fields are for entry of the bird name, one field being the Common Name and the other being the Latin Name. They are both drop down lists that contain all the birds from the table, this being done by import data. The table that holds the bird list has two fields One is called Common Name and the other is called Latin Name, this being the same as the filed names in question in the Bird Entry From
This is where I am coming unstuck. What I would like to happen is that when I enter a bird in the Common Name field (either by typing until the bird is auto entered from the drop down or using the drop down to find the bird) it automatically enters the Latin name in the Latin Name field and visa-versa, but I have become very frustrated with trying to do this.
Am I wasting my time? Or is it possible? And if so would anyone be kind enough to tell me how?
Many thanks,
Simon.

Aug 14, 2005As you all know Im not a expert on databases but work in a volunteer basis in a small community area where we have no money for people to do anything for us.
Im proud because I did the other database and its up and working but this one has got me beat.
Im setting up one for the volunteers, which has computer knowledge, any basic training they need, when they are available and what tasks have been set for them.
I need to have a one form which has just their personal details but to be able to put in data on the other forms and it will link back to the volunteers name.
Ive attached what Ive done and Im sure your all going to laugh - but any help would be appreciated

Many To One Relationship (I Think...)
Aug 19, 2005Trying to set up a fairly simple DB. Here is the layout:
tblRoom(roomID, roomNumber, rackOne, rackTwo, rackThree)
tblStudent(studentID, name)
Each student will be assigned to one, and only one, rack. There will be 3 students to one room. One student can only have one room but a room can have many students... I store studentID in the rackOne, Two and Three fields. My problem is when I try and querry for the information so as to display actual names rather than ID's. I'm not sure If my querry is the problem or if I've set the tables up incorrectly. Any insight is much appreciated.

Mar 3, 2006I was wondering if anyone could help me with a query. Basically I am doing (or trying to do) a small database to track childrens progress in my mums primary school. I'm doing this for free as the budget is rubbish for this type of thing and i dont have enough knowledge to ask for payment anyway! I want to get it right from the start and I think if I get the relationships right initially then I can complete the rest of it on my own. I did this at university (normalisation etc) but ive not used it since i left in 2002 and so have practically forgotten everything i ever did.
Basically, the child comes into the school and is predicted a level in maths, reading and writing. Then in the october, feb and july of each of the 2 years they are there, they are given actual assessment levels. They are also given a prediction level at the beginning of year 2.
So far I have one table with student no, surname, first name, gender, ethnicity, year group and SEN(special educational needs) - with the primary key being student no.
This is where I get stuck - do I go for a maths, reading and writing tables and split it that way - or on an assessment basis, so prediction yr1, october yr1, feb yr 1 etc etc. Or is this completely wrong? Am sooooo confused, so any help would be greatly appreciated.
The outcome I want is to be able to query a childs progress, so for example: show children who achieved a 1a in yr1 maths, and then out of those children, who achieved a 2a in y2 maths (as this is the required shift in progress set by government). I really hope that makes sense.
Thanks in advance

One-to-One And Many-to-Many Relationship
May 10, 2006I'm rebuilding my database from scratch now that I've learned a bit from the forums about developing a proper database and I want to investigate whether I have the relationships set up correctly, as I seem to be using lot of one-to-one relationship, which most articles say is very rare, and whether I am formulating many to many relationship correctly. Here is a screenshot of my relationship.
If I've understood this correctly, one-on-one is desired if you have a subset of data that is applicable to the main table only occasionally and is dependent on the main table's data. Have I used that correctly?
As for many to many relationship, articles say this is formed by having two one to many relationship linked together in a table. In my screenshot, you can see that tblAdvocacyVisit is the linking table. However, I've set GuestID as a one-one relationship whereas ClientID is one to many relationship, reasoning that since I do need to relate the Guestl Logbook data to Advocacy table for some queries I will be performing later, this will save me some work. I'm afraid that this may compromise RI or something like that. I can simply add a PK autonumber to tblAdvocacy to revert the GuestID as a one-many relationship, but can't see how that would not create more work in queries or so...
Oh, are the lookup tables supposed to be related at all?
TIA.
Edit- Updated the relationship screenshot.
Many-to-many Relationship
Jul 27, 2006I’m building a database of protein mutants we use in the lab. A lot of analysis is done on these proteins by various people and it’s becoming a bit of a nightmare keeping track of all the information per protein. What we need is a database. I’m getting a reasonable grip on it all I think with the excellent examples I have found on the forum but there are obviously areas that I have great difficulty with. The main problem for now is that many-to-many relationships are involved and I just cannot get them to work properly.
On each protein up to 8 different types of test are performed. To keep things easy I’ll call them A1 (for Analysis1), A2, A3 etc. These are done by different people from a group of 7. I’ve called them O1 (Operator1), O2, O3 etc. Each of the operators can do multiple analysis and the operators overlap. So e.g. O1 might be particularly good at A1, A4 and A7, O2 might be good at A2, A4 and A5, and O3 predominantly does A1, A4 and A6. What it comes down to is that each operator can in principle do each of the analysis so I have to give that option in the database.
What does work (but is not the solution as it introduces 8x duplication of data) is if I have a separate table with operators for each analysis. The same tblOperators is linked 8 times. There must be a way to link each of the analyis to only 1 tblOperators, probably with the use of a linking but I just cannot work it out from the examples I've found here.
Can someone help me on my way please?
Thanks,
Walter

Nov 20, 2006New guy on the block here.
I am having trouble associating the relationships within a database to accomplish what I need. I don't know if I am over thinking or I just plain old don't get it. So, I ask if someone can draft this database up rather easily and post it for me or send me in the right direction to learn quickly.
This is what I am looking for: A table with people’s first name, last name, title, job position. That is it. I can do that and have done that. No problems.
Another table that has amplifying data on that person such as: date of birth, SSN, date employed, comments, etc.
What I envision is, creating a form to add the names, title, and job position of the people to the table.
Then I want to create another form that puts the other data associated with that person. This other form should have the first and last name from the first record to "view" only so the correct data can be added to the correct person.
That is it; I hope someone can help me out. I have been working on this for sometime and just can't seem to get it.
Thanks, all, E-dub
Many-to-one Relationship
Dec 7, 2006Please pardon my inexperience.
I have two tables, call the tblSales and tblCustomers.
tblSales looks like this:
CustID FName LName ...
1 John Doe
2 Jane Doe
1 John Doe
1 John Doe
2 Jane Doe
2 Jane Doe
tblCustomers looks like this:
CustID FName LName
1 John Doe
2 Jane Doe
with CustID being the primary field.
Suppose that no data exists in the FName and LName columns of tblSales. How could I automatically populate those fields with data based on the information in tblCustomers? I would like to be able to simply type in the CustID on tblSales and have the other fields populate automatically.
I'm sure Access can do this, but how do I set it up!?
Thanks!
What Relationship To Use
Feb 7, 2007Hi all,
I have following problem so please help if you can.
I have three tables: Order Demands (from production), Order Demand Details and Orders (for placing by different suppliers).
ORDER DEMANDS
Order Demand No.(ID)
Date
ORDER DEMAND DETAILS
ID
Product
Quantity
Order Demand No.
Finished (checkbox)
ORDERS
Order No. (ID)
Date
Product
Quantity
Relationship between Order Demands and Order Demand Details is one-to-many. I have no relationship between Order Demands and Orders but it should be actually many-to-many relationship.
Following must be possible:
Order demands with specific details come from the production. It can be one item or several items (products) that are demanded. I must be able to place an order for one or more items (products) which are unfinished (not ordered till now) by selecting items. I must also be able to place an order independently from Order Demands for example because not all demands come from production department. After I have placed an order and the ordered products were supplied then I must be able to enter received products (maybe I do not get all ordered items) into Orders form for instance and this should check the field "Finished" in Order Demand Details table so that I know that I have received the products that are demanded from production department.
Do you have any suggestion how to organise relationships between tables.
Thanks for your assistance.
