I have a table named [Brand] and several tables named [Brand@@@Models], one for each field in the Brand table.I want each field from the [Brand] table to be related to it's specific Model table. I thought like that so I don't have a Brand#1 related to Brand#2 models, etc.. I didn't want to have all the models for all the brands in a single table, was I right to think like this?
View RepliesHi,
I am creating some table for a database I want to use.
I had the following tables:
[Organisation]
orgOrganisationID (primary key)
orgName
orgPostalcode
orgStreet
orgCity
orgCountry
[Contacts]
coContactID (primary key)
coSurename
coFirstname
coFysicPostalcode
coFysicStreet
coFysicAdditions
coPostPostalcode
coPostStreet
coPostAdditions
coTel
coFax
coEmail
[Postalcodes]
poPostalcode (primary key)
poPostalCity
poPostalCountry
I have two postalcodes in the Contacts table. I can't create two one-on-many relations from the Postalcodecodes table to the Contacts table.
So I thougt I split up the contacts table and create a one-on-one relationship between the two new tables.
So it would look like this:
ContactsGeneral
cgGeneralContactID (primary key, autonumbering)
cgSurename
cgFirstname
cgFysicPostalcode
cgFysicStreet
cgFysicAdditions
cgTel
cgFax
cgEmail
ContactsPost
cpPostContactsID (primary key, numeric)
cpPostPostalcode
cpPostStreet
cpPostAdditions
I would create a one-on-one relationship between coGeneralContactID and coPostContactsID. And now I can create my one-on-many relationships between from the Postalcodes table.
1) Is this clever?
2) Should both these fields have a key?
3) I set coGeneralContactID to autonumbering and coPostContactsID to numeric. is this also correct.
4) I also use prefixes before the fieldnames 'cp-' for 'ContactsPost' is this naming convention ok? I think it makes programming easier. But are there condingstandards for that in Access/VBA?
Thanks,
Jayke
I have a DB and for some reason queries aren't working properly. My guess is the table relationships I made. If anyone else has an idea on changing my relationships so that all forms and queries will work to thier full potential please give my DB a look.
Any Help will be greatly Appreciated

Hi all,
I built a database and I was wondering if anyone has any suggestions on how to normalize my DB. I think my table relations are wrong.
I'll post my DB for you people to view.

I have 10 tables, 30+ fields on each table (every table has the same 'account number' field). I only need from 5 - 20 fields from each table. How do I get the certain fields from each table and put them in a table, query or report?
View 1 Replies View RelatedWhat I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.
I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...
*Child_ID
Parent_First_Name
*Primary/Secondary/Other
I have three tables: Vehicles; Vehicle Reallocated; and Vehicles Retired. I have a form that runs a query to find all the info in the Vehicles tbl that is not "Retired", not visible in the form. I then have the option to toggle to a Reallocated or Retired form. When i toggle to the reallocated form, i have the like fields in that table (ie Van #, Vin, Make etc) pulling the info from the hidden subform with the vehicle query, so i do not need to fill in repeat data. However, when i add a reallocated date and the new clinic that vehicle is for, i get the record ID for the vehicle reallocated table as expected, but when i save none of the data moved over from the query saves in the record?
How to get all the data on the reallocated form to save?
Well I'm hoping someone here can point me in the right direction. This is my problem... We've got about 50 Access databases scattered across the network. Each network database contains the same tables and fields, but of course, each one contains different information (one network database is for DepartmentA, another network database is for DepartmentB, another network database is for DepartmentC, and so on).
What my boss wants is a single table/view that displays all the information contained in every network database table. The other part of this is that my boss then wants to be able to make changes in this single, all encompassing table/view and have those changes be pushed back out to the individual network databases. Is this possible? And if so, can someone help point me in the right direction? I'm still a little new at Access, but I can manipulate VBA code and all that if need be (I'm learning more and more as I get deeper and deeper into this project).
Thanks!

I am currently designing a database to solve our organisation's training requirements. The db needs to be able to identify an individual member of staff at any particular site and list all the medical devices that they have training on and to what level of competency. So far I have five separate tables:
Staff details
Site
Devices
Competency/Risk
Equipment
By using unique identifiers within each table, we can, in theory, comply with the requirements.
Now here is the problem. Having talked it through with a colleague, we have two possible options.
A. Using a form based on the staff member, combine the salient details and, where needed, create additional fields (such as dates and tick boxes) to record odd items (this is my preference)
or
B. Based on the site, create a make-table query and form a table, sorted by site and then staff, listing all the equipment and competency levels. Given that some staff will work at multiple sites, the table will probably contain over 6500 records with lots of duplication (you can see my bias!)
Which solution is probably the best or should we be looking at solution that combines elements of both?
Thanks in advance

I have to assign multiple table validations to my table but they are not even working separately.
1) I have two combo box controls: [Tocolytics] & [multiple_Tocolytics], 3 check boxes and 1 text box.
Rule:
IIf(([Tocolytic?]="Yes" Or [Multiple Tocolytic?]="Yes"),([Indomethacin]=True Or [Nifedipine]=True Or [Nitroglycerin]=True Or Len([Other])>0),"check one of the boxes")
2)Two combo boxes The answers are mutually exclusive. If one is yes then the other must be "No" or "unable to determine"
Rule:
IIf(Oxytocin Infusion - no PPH]="Yes",([Oxytocin Infusion - if PPH]="No" Or [Oxytocin Infusion - if PPH]="Unable to determine"),[Oxytocin Infusion - if PPH]="Yes")
I have a store database containing multiple values about a single product, and separate table on color that this product comes in and in another table are quantities this product is available in. How can I make relationships between the tables so it works and I can make queries from it?
View 2 Replies View RelatedI have quite a limited knowledge of MS Access (2007).
My question is; How do you use sections of one table in other tables?
For example: In tbl_One I input a users Name and Age and then say Weight, Height, BMI, etc.
Then in tbl_Two it uses the same Name and Age in tbl_1 but has other information such as Job, Skills etc.
This is not my actual database, however this analogy works, and they must be in separate tables, even though above they could all just be in a single table.
I have a big number of sales staff..and broken them into different teams.
I have one TABLE1 with all their names, i need to have table which links to TABLE 1
All the fields are the same except team field. Therefore i need table 2 to only show me all fields and TEAM ALPHA only.
In total i got 46 teams therefore it is big.
Hi,
I've split a database and the backend relationships are still intact but the front end they are not and it looks like this is causing a problem. Is this usual?
How do I make the reports show in relations?
I'm (as said before) totally new to everything that has to do with programming, and therefore I work in the visual way, and thus I need to have the reports shown in relations in order to work with it...
Any ideas?
After designing the database that mean after creating all the tables and when pressed on relations buttuon it shows a diagram with relations established. Is this a kind of ERD. in this it shows relations between entities so can we call that an ERD?
View 3 Replies View RelatedHi there,
I'm a bit stuck on this but it should be pretty easy.
Say I have a table secondHandCar - this contains infromation on the makeID (eg 123), price, number of doors. Now each car can have a number of images, this number isn't set so I have an images table...
tbl_secondHandCar
makeID - key
price
number of doors
tbl_images
makeID - key
Image (ole, binary whatever)
Now clearly I have a problem: the images table is going to have many makeIDs with different images. I've just got stuck here - do I need an image id or something? But then my make ID will still repeat in tbl_images.
Thanks for the help :rolleyes:
Please could you advise me if tables have to be linked in order to perform a query on multiple tables? For example searching for a date and matching records on more than one table at the same time.
View 1 Replies View RelatedI have three tables, with the following data (fields separated by "-" here):
Unit - Customer Number - Customer Name - Type of A/R - Total A/R
Unit - Customer Number - Customer Name - Type of A/R - Total Overdue
Unit - Customer Number - Customer Name - Type of A/R - > 90 Day Balance
I would like to combine these tables into one table with the following field names:
Unit - Customer Number - Customer Name - Type of A/R - Balance
When I append the data, it comes out like this:
Unit - Customer Number - Customer Name - Type of A/R - Total A/R - Type of A/R - Total Overdue - Type of A/R - > 90 Day Balance
I would like this new table to include all rows from the original tables, sandwiched on top of each other. As far as I can work it, the Append Query only adds the data as add'l columns; not as add'l rows. I tried changing the field names entirely, so that the final field in each table is called "Balance." However, I still get the same result as above - the columns are added, instead of rows. I swear there's a way to do this, I just can't remember it!
I am great with Excel but not soo much with Access 2010. I Excel, what I needed to do was very simple but duplicating what I did in Access is not soo easy.I am trying to calculate billings for FSA & HRA. I have set up one table with all the data. I want to add columns to the table to calculate:
1. Is there an account balance-excel formula:
2. If the account is still active
3. If the plan year run out is "active runout" or "runout over"
4. calculate each account type with a rate *count of FSA accounts = total to bill
Here are my excel formulas that for the life of me I can't get to work.
Account balance==IF(V2="HCRA",(IF(AB2-AD2>0,"Available Balance",IF(AB2-AD2=0,"Zero Balance","Negative Balance"))),((IF(AC2-AD2>0,"Available Balance",IF(AC2-AD2=0,"Zero Balance","Negative Balance")))))
Active runout/runout over=
=IF(AG2="YES","Active Runout",(IF(S2=W2,(IF(AF2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")),(IF(AE2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")))))
Active account=
=IF(D2<$AJ$1,"NO",IF(W2>$AJ$1,IF(S2=W2,"YES","NO") ,"NO"))
Can I have calculated fields that refer back to a calculated field?

I have a risk table containing risks and risk owners (many owners for one risk), meaning that I have two risk owners columns. What I would like to do is to connect both risk owner columns (containing the name IDs) to the Names table. But Access does not allow to connect more than 1 column to another.

How can I import from multiple tables into one table without replacing the destination table.so that the destination table consist of old data and new imported data.
For example: I have table A with date 130205 and I need to import from table B and C which the dates are 130206 and 130207. Those 3 tables already have the same column numbers and data type.
I'm trying to create a database at work keep track of projects I'm working on and all the different events that happen during the project.
I want the main table to be customers, which will include the job number (as the primary key) name, address etc. Then I need other tables that have information about the building permit that will include dates city names etc and then another table that would include information on our sales people and so on, there would be maybe 5 tables that all connect back to the customer table.
I have tried this several times and keep running into problems, I'm sure it has something to do with the relationships. I'm missing something. I can create 2 tables and it works fine but once I add a 3rd it wont work.
Hi,
I'm trying to build a mdb which holds customer details, which insurance they have, who sold them this and which Insurance company provided this.
The relations I have to make are driving me nuts !

Who can help me with the proper relations ?
Attached is screendump of the current relations.
Thanks a lot !
