A Simple Relationship Question From A Newb
May 3, 2005
Ok, I have studied up on relationships, and read a lot of these threads but, I still have yet to find help. It seems a lot of the people on here have difficult problems that require dificult answers. Basicaly I have two tables Tblresort and Tbllifts, now there can be many chair lifts for each ski resort, so this would call for a many-to-one relation ship. Now, I create a relationship for the fields, and enforce refrencial integrity and all that. Now what do I put into the related field in Tblresort to get the lifts with ID#'s 1-8 to be related to the first resort.
I hope this all makes sense, so far I can only get one lift conected to the resort.
Thanks in advance

I have a form that I created using autoform from my main table. The form is just for the user to enter a new record. But when opening the form, how do I get the fields to be blank and on a new record by default, rather than starting on the first record with the fields already populated?
And then if I make a button that says "add" but just closes the window, the data should automatically save right?
Thanks.

I am fairly new to access so please excuse my lack of knowledge. I am using Access 97
What I am trying to do is create a system where I ask for a zip code, then disply the closest 5 results to that zip code.
I currently have every single city with ZIP code in Michigan. I also have the list of results with their zip codes.
Since you cant relay on ZIP codes going in order, I also have the Latitude and Longitudes for each ZIP code. Of course I have the lat and long for my possible results.
How can I get the 5 clostest results based on two different factors (Lat & Long)? Would I want to construct a Query to do this?
Any tips or sites you can refer me to would be great! Thank you!

hey,
Am new to the forum and it seems a good place for help,
Am having some big problems with a database that i am using for a company. The problem being that users need to enter ref numbers for each record on to the database called "c3" numbers, there could be a unlimited amount of these numbers(they do need to be able to reported on though) per record
At the moment i have a serperate form linked to my original form with a lot of seperate fields labelled like "c3number", "c3number1", c3number2" and so on which the user enters the c3 numbers into ans saves
however it is becoming very hard to do counting reports with it set up like this.
has anybody any ideas's on how i could make the setup simpler?
many thanks
Steve

I have to create a new table for some data I have from work. The data was imported within quotations though, so it won't let me copy and paste it untill the quotes are removed. I have over 3000 data values in each column, so I can't just go through and delete every quotation mark. Is there any way for me to select a column and remove the quotations around every value?
I have the XP version, by the way.
Thanks !

I am brand new to Access/VB as of Thursday. I am an aspiring programmer still in college. My proficiencies are more to the c++/HTML side of things right now, but I am in dire need of some assistance. I was recently given a series of projects to determine if I am qualified for a particular job. I have completed them all but one. I am modifying an invoice form in Access. I have accomplished all but two of the tasks on this last project. I need to modify the invoice form so that whenever a payment amount is entered, the payment date box I created populates with that date. I know I'm really close to it, but I keep getting errors and the only thing populating the box is #Name?. I also need to open up the print/preview mode of the invoice report when I click the print button as opposed to the current form it opens up to print from right now. If anyone could offer any assistance/advice on anything...even a tutorial that might point me in the right direction that would be excellent. I have until Tuesday to figure this out =) Thanks a bunch in advance!
P.S. This is where I thought I needed to execute the update for the payment date since it is where the payment is entered. If this doesn't help at all then I apologize.
Private Sub I_Payment_Exit(Cancel As Integer)
Me.I_Tax = NullToZero(Me.I_Subtotal * Me.I_TaxPerc)
Me.I_Total = Me.I_Tax + NullToZero(Me.I_Subtotal) + NullToZero(Me.I_ShipChg)
If Me.I_PaymentLock = True Then
Else
' Me.I_Payment = Me.I_Total
End If
Me.I_Balance = Me.I_Total - NullToZero(Me.I_Payment)
End Sub

Hi. I'm quite poor with Access, so sorry if this sounds dumb.
I have a table of customer records (tbl_customers), including name, address & postcode etc
I have a spreadsheet of customers their postcodes from a different system that shows customers who have bought a particular product.
Is there a way that I can create a query that lists those records in tbl_customers whose postcode is matched in the spreadsheet?

Ok I am right now making a simple Vendor/Product database to create a line sheet for some sales folks. I have 3 tables: Vendors, Products, and an associate entity Vendors_Products to relate the two. I have a form currently that draws the Vendor Name (primary key) from the Vendor table and the Product Name from the associate entity. This allows me to create new vendors and select current product types from a drop down box. The problem is that the drop down box is too long and it is tiresome when 1 vendor has 10 product types.
Can anyone tell me how to resolve this? I thought it would be better to have option buttons and display all available products. Then you could just click all of the option buttons that apply to that Vendor and it would create the relationships...is this possible?

Hi 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.

As 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

Trying 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.

I have a one to many relationship between the movie and date between the attendance and movie data table. I have tried linking the name to the usher fields but I"m not getting the result I want. I want to be able to open up the volunteer table and have it show me the movies they have worked on. The movie data table will list who worked it, but the volunteer tables are not.
Any ideas?
Thanks,

at one point in my database I have two tables and for everyone record in one table I may have either 1 or 0 records in the other. How do I express this in access design? Since it's an optional 1 to 1 relationship I guess?

I 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

I'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.

I’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

New 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

Please 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!

Hi 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.
