hi..
Im struggling to get the relationships correct within my database. (4 tables)
It's for a shopping cart application
Can someone please help:
tblcustomerdetails:
custid
forename
surname
addline1
addline2
postcode
email

I am trying to consolidate data from a proprietary database that was built for a DOS based point of sale application. The database is basically a series of flat files. I have managed to get the data into SQL Server but I am having trouble getting the Joins correct so that the data shows the way I need.
For instance here are three tables
http://www.liberty1st.org/x_access/rel01.jpg
The results I would like to get is to list all the employees along with a total of Worked Hours and the amount of Cars Worked on.
The Query looks like this
SELECT
dbo.EENAME.EECODE,
dbo.EENAME.NAME,
dbo.vHoursWorked.TOTAL_HRS,
dbo.vCars.CarCount
FROM dbo.vHoursWorked INNER JOIN
dbo.EENAME ON dbo.vHoursWorked.EECODE = dbo.EENAME.EECODE INNER JOIN
dbo.vCars ON dbo.EENAME.EECODE = dbo.vCars.EECODE
The results I get only show one employee over and over (EECODE is the Employee number).

What I am doing wrong?
Hello everyone, as you may have guessed i have a problem
so i have a table with a one to many relationship with another table...everything's cool except when i want to query data it will query fine from one table or another but i really want to return data from the related tables as well.
simple question i know but i cant seem to figure it out
helpppp
Here I have three tables.
Control type – has a field control – 1 row
Table1 – has fields: Acct (text), table 1(text), table 3(text) – 8 rows
Table2 – has fields Acct (text), table 2(text) – 4 rows
What I am looking for is to combine Table1 and Table2, replacing table 1 with table 2 if the control type is 4. if its not then it uses table 1.
I was able to do that with the query test except I lose that data in table 3 that doesn’t match table 2.
I would like to have the information kept on Table1.[table 3] and if nothing matches [table 2]
It sounds confusing so I am attaching the database.
The Query test shows it working but losing the extra data from Table1.[table 3]
The Query test2 gives the SQL Err I received when it runs the way I thought It should.
Any help or suggestions would be welcome.
What I am looking for is a way to set a stactic varable that only changes when I set it. and is available for 4 or 5 different queries. run under the same macro.
I have two tables that look like this:
Table 1
LOCATION NUMBER , SIZE
1.12 ,100
1.13 ,100
1.14, 12
1.15, 12
1.16 ,150
1.17 ,150
1.18 ,100
Table 2
ITEM , SIZE
A , 12
B , 12
C ,100
D ,12
E ,100
F ,100
G , 150
I would like to do a query that Joins the "Size" in each table, and then matches an "Item" to a "Location". However, because of how a normal join works, I cannot seem to figure out how to limit the "Location" field from producing duplicates in the match.
I only want to have 1 location for every 1 Item.
Hi all. I really need help with this. Does anyone see a problem with my relationships , i have attached a copy.
Any help will be greatly appreciated

I am new to database design and curious about relationships. In a hypothetical situation, if I have four tables: tblProducts, tblOrders, tblEmployees, and tblCustomers, how could the relationship be set up?
The Products are stored to keep track of the quantity on hand and the employees will also need to be tracked as to how many products they sell. Customers are recorded and Orders wrap up all three tables with the fields: OrderID, ProductID, EmployeeID, and CustomerID.
Would it make sense to say that many products can be bought by many customers and/or many employees can place many orders.
Hi
I've selected a number of tables to the relationship window. When I drag the primary key on one table to the corresponding foreign key on another table, the link created is one-to-one. I want one-to-many. Why did it create one-to-one? How do I change this to one-to-many?
Thanks
Hi all. I am new to the use of access and have been told that I need to create a one-to-many relationship to be able to have several records from a drop down list saved to one unique number (my primary key).
Is this correct and if so how do I do this? If it is not correct what is the best way to do what I require?
Thanks for helping.
Hi
I have created two tables which are linked with a one-to-many relationship
Using a form the user enters a date. Then in VB I add a value to the date and store this in the second table.
I have simplified this to try to find out what was going wrong and found that when the database adds a value to the second table which only has two fields it first of all adds it to the begining of the record set and the id field does not update to that of the first table where the relationship is joined.
Do I just captutre the value of the id field and add this to the recordset.
How to I get the database to look foir the end of record set before I appent the new generated record.
Hi,
I have looked for this on the help section; however, it does not seem to be covered. How would you change a one-to-many relationship to one-to-one? Access seems to automatically guess that the many side is where the foreign key.
Can it be changed from Access or is entirely on how you design your tables?
Thanks,

Hi !!
I am doing a school project on a school database. In my DB I have a table with all students records (eg. Student ID, Name, Surname, DOB, class etc) and I have another table where the student fees payment slips will be printed.
The fee table will only have the ID, name, surname and class fields and fee will be input for every student for every term.
I want the fee table to get all the info except the fee from the first table automatically when I give a student ID.
I have created a one to many with only Student ID fields linked, NOTHING.
Then I tried to link many fields on each side (eg Name to Name, Surname to Surname etc) but I got a msg "No unique index found for the referenced field in the primary table"
Plz help me !!
Thanks
would having a db with several tables and NOT setting any relationships up in the relationships window affect the db in any way?
i have such a db, which originally had all the relationships set etc. however, as i encountered errors and had to replace tables and delete entries, i must have at some point deleted all the relationships.
i just relaised that the db now has no relatioships set up (all the primary keys are still in the tables) so i'm wondering if this matters?
cheers

I'm trying to define relationships between a few tables in Access 2003 and It's only doing a one to one. How do I get it to do a one to many?

I am designing a database for a clinic
basically,
One Form is a Demographic Form, which was been designed. Each person was given an identifier code.
However, they all did 3 questionnaires. Each one of them has their ID code on it.
Is it possible for me to make a query so that when I search ID code, it actually brings up all the information on every questionnaire?
If I have a table "tblContinents" with just two fields ContinentID and Continent and I have another table called "tblCountries" with three fields CountryID, Country and Continent.
After reading several articles, i decided not to make the Continent field in the tblCountries as a lookup field but rather I will do that at form level via a combo box. In such situation, since i am not creating a lookup field at table level, do you think that it is necessary to create the relationship between the two tables in the "relationship window", or shall i just leave it as it is, and if the need arises i will create such "relationships" in queries?
Thanks very much.

In my Db I have TblQuotes & TblQuoteItems
I want the one-to-many relationship to be based on my own generated quote reference rather than the PK/FK.
My quote reference looks something like this IN123/10
Does the character '/' cause a problem with creating the relationship as I get the error message "No unique index found" even though I know that they exist?
Thanks
When I view the relationships window, not one of the relationship connector lines (whatever the technical term is) do not show up! I click view all relationships, view direct relationships. I restarted my computer, restarted Access. Nothing!
I know I have relationships because when I am table design view I try to change something that I know has a relationship and it doesn't let me because it says I have a relationship.
What is going on!?:mad:
Hello..
Here is what I have. The database is made up of three tables (see below and see attachment). I have it set as one event to many ethnicity's and many personnel with the event ID as the PK in all three. Did I do this correctly? I thought I did and I had a form with each one of these running correclty but now it is not working.
tblEvent
EventID(PK)
tbleventEthnicity
EventID (FK)
tblPersonnel
EventID(FK)
See attachment for the other fields.
Can someone just check to see if I set this up correctly or what I should do differently?
Thanks
I have already made a relationship 1 to many, i want to add another relationship. I put the name of the feilds i want to join up in the drop down box. I put "enforce in..." and "Casgade update related fields" on and join type 2. Then when i press ok, it comes up with "file title " to "film title" and comes up with "no unique index found with the referenced field of the primarytable".
Does anyone know what this meens?
I am writing a access database for work(fire dept). It is a database for the vehicle checks. Most of the fields are Boolean fields we just need to know if the inventory is on the unit. I am kind of new to this. My tables so far are as follows:
TCardiacMonitors
TFirstInBags
TGlucometerKits
TIntubationKits
TUnitNumbers
TCompartmentNumberOne
thru
TCompartmentNumberEight
TSealNumbers
TEngineChecks
all list the inventory that is supposed to be in that table
Everything is dependant on the Vehicle it is on so my question is Do I relate everything to a look up field in TUnitNumbers(intUnitNumberID) or is there a better way to do this? I need to relate everything to the date it was checked
Thank you for your help Bill
OK. I'm not real sure how close I am on this. I have a feeling I'm not too close so I was hoping I could get some help. I have a database with 11 tables. These can be seen in the screen capture attached. For the 'Action Taken' table there are 10 fields for 'Departments Involved', 15 fields for 'Memo Sent To', and 15 fields for 'Job Title'. The 'Departments' table is linked to 'Departments Involved1', the 'Memo Sent To' table is linked to 'Memo Sent To1', and the 'Job Title' table is linked to 'Job Title1'. All the other tables are showing the fields that are in that table. When I enter a record and try to go to a new record it gives me the following error message.
"You cannot add or change a record because a related record is required
in table "Background Information'."
I'm not sure what to do about this. I'm sure there is a simple solution but I don't know what it is. I am pretty new to Access (this is my third week on the job) and a little confused on some things. I would appreciate any help you could provide.
Hello. I'm new to databases and anything I know I've read up on. I know that relationships are essential so I'm trying to sort a database in ms access that I have inherited at work. It contains health service staff and their record of training - various training that they do regularly. I've managed to put the data in 1nf but am having difficulty after that.
A couple of questions:
If I give each staff member a unique id do I need to link their job title to it? Job titles chang quite a lot.
Other information about courses, dates of training, trainers etc. - should they be linked to staff name via separate tables?
I'm using a spreadsheet example from microsoft that shows me how to go from raw data to 3nf but I'm not sure how to split the information, so if you have any suggestions or know any good guides I'd be grateful for your help.
Thanks.
I have 2 tables. tblcontact and tblboat.
tblcontact
CustomerID-PK
Customer
Contact
tblboat
CustomerID-FK
boat
Serial
i have made a form to enter the data, all works ok. I built a form to search by customer and it works fine. I can not find a way to build a form to search by boat name or serial. Can some one please help?
Thanks in advance!

Hello. I posted a while ago on a database I'm working on. Still having trouble with relations. These are the fields in 1nf:
FNAME
LNAME
JOB_TITLE
BASE
DEPT_WARD
COURSE
DATE(S)_ATTENDED_COURSE
COURSE_TRAINER(S)
COURSE_VENUE
CERTIFICATE_ISSUED
The database keeps a record of various training courses for health service staff. From answers to previous posts I figure I need:
TBSTAFF
STAFF_ID
FNAME
LNAME
JOB_TITLE
TBCOURSE
COURSE_ID
COURSE
TBTRAINING_DONE
STAFF_ID
COURSE_ID
DATE_TRAINED
TRAINED_BY
CERT_ISSUED
I think that's ok but it's when I try to link them I get into trouble. Assuming the above is correct do I have:
TBSTAFF linked by STAFF_ID to TBCOURSE-COURSE_ID
TBSTAFF linked by STAFF_ID to TBTRAINING_DONE-COURSE_ID
I'm not sure how base and dep/ward work either. I need to know a person's base and dept e.g. hospital x, ward y.
Thanks.
