Table Field Design Help !!!
Apr 30, 2005
Recently I'm helping a friend to convert his MS-Excel spreadsheet into MS-Access. I met a problem and need some help on defining the table fields.
In one of spreadsheets, he gets 3 columns, the 3rd column values is calcuated by a formula based on the previous two entries as the followinf: D3= C3+B3
When I tried to turn this table into MS-Access design, I don't know how to define the 3rd column (field).
Is there any chance I can set any expression/formula for 3rd field in the table defnition to retrieve data from previous columns( I don't want to design this function in the query)?
Many thanks

I am making a new Record in the design view of a table (creating a new field in the table), and I am assigning it a date type, is there a hotkey that will select the field properties sheet so that I can select the format of the field without having to move my mouse?

Hi.
Other than manually moving fields in a table in design mode, can I get the fields alphabetized?

I was wondering if there is a way to export the Table Design Structure:
1) Field Name
2) Data Type
3) Description
Into a Spreadsheet.
I was able to do this a long time ago, but can't seem to remember. I'm using Access 2000.
Thanks!

Hi im stuck on filtering a combo box (i am using an sql query to populate a combo box with a filtered selection, this is in Access but im after some design sanity checking). I have users who can be assigned a category. Jobs can be assigned a category and also have a list of people working on that job (in the JobDetails table). I have the following tables:
Categories Table:
CategoryID (PK)
Description
Users Table:
UserID (PK)
Username
CategoryID (FK on Categories.CategoryID)
Jobs Table:
JobID (PK)
CategoryID (FK on Categories.CategoryID)
JobDetails Table:
JobID (FK on Jobs.JobID)
UserID (FK on Users.UserID)
Then in the job details when listing users for a job (many users can be for one job) i would like to only show the users which have the same category as the jobs category. Is this possible? i tried the SQL below for the lookup column field JobDetails.UserID but it doesnt work:
SELECT Users.ID, Users.Username, Users.CategoryID
FROM Users, Jobs
WHERE (((Users.CategoryID)=[Jobs].[CategoryID]));
All the tables are linked with relationships but my SQL isnt so hot!
Any ideas as to how i would do this and get it working?
Even if it can be done, is this even recommended? I can see funny conditions happening if the job details category changes or the users category changes then even if they are existing in the job details list they will not be shown? Even so, i would be interested in the above to know how it is done (if possible).
Thanks in advance,
Chris

I am just querying a single table, no relationship involved with another table. As you can see form the attached jpeg, the ZIP field in some cases is empty. I would run a search using Is NULL but the field is NOT numerical. It's a long story but I had to make this field a TEXT field. Basically, what statement do I have to insert in the criteria field to just pull up the EMPTY ZIP fields?

I have a table called NewTransactions_tbl that I have been using for some time. I am trying to add a new field called CustomerProjectNumber. It's not being displayed when I look at the table view. I've attached an image showing the settings for the field. I am probably missing something obvious.
Any ideas why it is not showing?
I am using Access 2000.

I am designing a database for my organisation. I have done most of it but am stuck on this. Ideally I would like to have a check box (in a table) that when checked a load of data is carried across from that record to a record in another table.
Given that I can't and don;t want to use VB is there anyway that this can be done easily?

I am having problems coming up with a Table design and need help.
I am trying to design a table that will have 8 categories, 47 subcategories, and then choices within those categories.
Much like the following (this is only one category example, there will be many):
(Main category) Floors -> (Sub categories) Joist, Carpet, Vinyl Flooring, Wood Laminate -> (Choices for Joist Sub Category) Structure Wood 2X8 Joist, Plywood 2X8 Joist, Structure Wood 2X10 Joist, Plywood 2X10 Joist
This only shows the flow if the main category is "Floors", sub category "Joist", and then the choices under subcategory "Joist". There will be others for the other categories, subcategories, and choices.
Can someone help me or steer me in the right direction in setting up the database table/tables to accomplish this. Oh and BTW, there will be prices attached to each "Choice" under the subcategories.
I hope that this makes sense... any help would be much appreciated.

Hi all, i wonder if anyone can help?
It's a simple question really. I'm currently learning databases and am doing a project, just to show that i understand everthing i've learnt so far. I have to produce a small database.
There's nothing difficult about the project, and its a very basic database, but i was just hoping to ask a small question.
I'm producing a DVD database, to hold details on a collection. My main table holds the majority of the fields, as follows;
lngDVD_ID
strDVDTitle
strYearReleased
lngDiscAmount
dtmFeatureLength
lngCertificationID
ysnBoxset
ysnExtraFeatures
strDirector
lngMovieStudioID
lngCategoryID
curPurchasePrice
The problem came with boxsets. Originally i was just going to have boxsets as one entry, but some contain a few dvd's, each with different certification, etc, and i wouldn't be able to record running length, director, etc.
So i added a ysnBoxset field (just to record whether a dvd was part of a boxset or not) and then made a new table with
lngDVD_ID
strBoxsetName
So now i can record which are part of a boxset, and the name of the boxset they belong to. But.. then i got to the problem of Purchase Price. Obviously i cannot record an individual purchase price for those which belong to a boxset, and i want to be able to record the price of the boxset.
So my question is... is it acceptable to add a curBoxsetPrice field to tblBoxsets, which would allow me to store the price... and then just leave curPurchasePrice as £0.00 for those dvd's in a boxset??? Or is there a better way of doing it? (I know there is, but i'm a novice :( )
Thanks for any help you can give, sorry for the lengthy explanation! :rolleyes:

Within my db I have a table, tblProjects which currently has 36 fields. Each project will have a fixed set of 12 tasks, each having a begin and end date as well as a yes/no "completed" field. This would add another 36 fields to tblProjects.
Instead, I have created a new table tblTasks which has these 36 fields along with a PK(TaskID) and FK(ProjectID) and is related to tblProjects. I believe tblProjects is already normalized properly with relationships to tblCompanies and tblContacts as well.
I'm not sure if this was neccessary, or should I have just added the task fields to tblProjects. What, if anything, are the advantages of one way over the other? I'll be upsizing to SQL Server, does that make a difference?
I appreciate any advice,
Sup

Hi,
Bit of a long one but I require some advise if people can supply it.
I've started creating a DB that is now getting out of hand due to me being inexperienced. The things I want to do now are getting way to complicated. From reading various posts I know that this is all being caused by my database design and while the DB is still young I'm go back to square one. I want your advice on this if you can to ensure 3 weeks from know I'm again not chasing up weird bits of VB code to make it all work.
I basically have a lot of information to hold that interconnects with each other. I'm making up a role profile DB (so we can assign define access rights to a computer system) I have lots of info to collate but the basic stuff is.
Staff Records (Name, business area & ID)
Applications (What computer applications do staff require)
Shared Drives (What access to shared drives and folders do they need)
Shared Mailboxes (what access to shared mailboxes)
Roles (users will be assigned roles to suit their requirements)
Basically what I have at the moment is below.
Roles
Role ID
Role Name
and about 15 other fields that dont really matter for this
Applications
Application ID
Application
Shared Drives
Shared Drive ID
Shared Drive
Shared Mailbox
Mailbox ID
Mailbox
Each role will only have a select number of applications, mailboxes and drives from the overall list. so role 1 may give access to 2 of the 10 applications, 1 out of 5 shared drives and 3 out of 4 mailboxes. Role 2 on the other hand may need 9 out of the 10 applications, 1 out of the 5 shared drives and 1 out of 4 of the shared mailboxes.
I just don't understand how I can create a form from these tables that would display all the different roles with their respective apps, mailboxes and drives they would need.
any advice you can give to help whould be appreciated.
Again sorry for the long post.

I am designing a db for our Law office. I want to have tables for different types of Civil Cases-ie Divorces, Deeds, Contracts, Personal Injury, Auto Accident, Slip and Fall, Product Liability, etc. The divorce, Deeds, tables are easy but I am having difficulty deciding on the personal injury tables. Heres my dilemna. Can I get away with one or two Personal Injury tables even though there will be blank data fields. For example, I will need a field for the name of the product in a Producrs Liability field. This field will be blank in all other Personal Injury Cases. I know the rule is you don't do that but my alternative is 15-20 tables for every concievable Personal Injury Case- Auto Accidents, Slip and Falls, Fraud, Prouduct Liability, Accounting, Attorney, Dental and Medical Malpractice, etc. This is in addition to other civil case tables, criminal case tables and federal case tables. Anyone have a suggestion?

I am not sure if which I should be using as the main entity for my tables. I am creating a database for hourly information on individual employees. Each employee will have the same types of hours to keep track of (weekly, bi-weekly, monthly etc) I naturally thought to treat each employee as the databases own entity and created fields for each type of hours but hit some trouble when trying to pull queries to compare each employees hourly information against each other to see who is being efficient or not. Each employee has the same exact fields but with just different numbers. We track each type of hour by week (Field One: Week 36, Field Two: Aug 28-Sep 03)This is the first time I am creating a database from scratch. All advice greatly appreciated and TIA :confused:

I have a table within a database and i was wondering whether or not i should split the table into 2 seperate tables.
The layout of the existing table is to record quotation information ie product codes, cost price, sell price, delivery dates available etc and it also contains fields that allow the user to state if the quote has been authorised or declined, when it was authorised and a number of options to explain the reason the quote wasn't accepted.
QuotationID - Primary Key
EmployeeID - Foreign Key
CustomerID - Foreign Key
EnquiryID - Foreign Key
ProductCode
Quantity
CostPrice
SellPrice
DeliveryDateAvailable
Notes
Authorised - Yes/No field Type
DateAuthorised
Declined - Yes/No field Type
ReasonDeclined
LostPrice - Yes/No field Type
LostStock - Yes/No field Type
LostDelivery - Yes/No field Type
LostCustomerClient - Yes/No field Type
LostNoFeedback - Yes/No field Type
above is the layout of the table, does anyone think that it might be a good idea to split this table into two tables, one table to record the quote information and another to hold the authorisation or decline information??????

i am creating a database for a local football club. I want to show player information (the main focus of the database), such as, what guardians are responsible for this player, what are the Doctors details for this player, what team does the player play for etc.
I have seperate tables for the Guardian, Doctor and Team information.
I also want to hold Staff details, (Name, address, staff title etc)
My problem is that someone in the staff table, could also be in the guardian table.
Should i combine the Guardian and Staff tables into one table as I dont want to have to enter the data twice for both a staff memger and a guardian
Note:
a player can have more than one guardian
a guardian can be responsible for more than one player.
What is the best way to approach the design of these database tables.
Thanks in advance

Have a database that I am working on this is constructed to perform Compliance tracking of wellness activity by employees. Have all my tables, queries and a form that has 3 tab controls as well as a subform on one of the tabs.
It is necessary to create a quarterly report card based on 6 wellness cateogories that have specific criteria. I thought I was OK but now I am having difficulty pulling it all together on the report. I now think that it has to do with my table construction and I am looking for advice. If there is someone I could send my DB to who can take a look and give advise or assistance I would greatly appreciate it. Thanks.:confused:

Hi,
I'm currently in an internship working solely with databases. I've become really interested in designing databases and I now want to design my own. I was wondering if I explained my table structure then someone could give me their thoughts and ideas for improvement. I have a huge sport trading card collection and I wanted to create a database for it. This way I could run some quick queries to find out how much my collection could be worth, how many cards I have, easily keep track of duplicates. Things like that.. This might seem strange, but I think it would be a good learning experience that would help me utilize many of the features of Access.
My Table Structure:
Ok I have a Company table(Topps, UpperDeck, etc) and they sell many boxsets(which would be another table).. Boxsets have many Cards(which would be my third table)...
Now here is where I get confused. I want have a sports table that would categorize my cards by what sport they are, but I don't know where I could link this. I also have a players table. This table will have a 1:M with Cards because 1 player can have many cards, but couldn't Cards and Players have a 1:1 because 1 card shows one player???
Finally, I want a Price Table that will be linked somewhere, but I've yet to figure out where to link this too.. Have I missed anything???
Your ideas and opinions are greatly appreciated!!!
Thanks!

In this database the Tables are:
Materials (Material_ID, Material_Name, etc.)
Users (User_ID, User_Name, Date_modified, Hour, etc.)
Enviromental Values Of Materials (Ev_ID,Cretarion_01, Cretarion_02, etc.)
So i want to build a relation like a 3d axis system like that:
X: Materials
Y: Envirometals Values Of Materials
Z: Users
So for each user may correspond with 1 or all of the materials and for each material many enviromental values(cretarion_01,cretarion_02, etc.)
Namely i want to do a database where a person saves a number of material (1 or all) and for each material a number of Enviromental Values(1 or more).
I make a relation (see attach file):( :confused:
What is your opinion about that?
It would be a broblem if the PK's type is text?
Thanx in advance....
Happy new year:)

Being a newbie I have a general table design question which I would be grateful if someone could advise upon.
In Access 2000 I currently have 3 tables for use in a holiday cottage rental system:
tblCustomer (customer details)
name (text)
address (text)
telephone (text)
etc.....
customerID (autonum)
tblreservation (cottage reservation details)
cottage (text) - linked to tblCottage
customer (test) - linked to tblCustomer
start date (date)
number of nights (number)
Adults (number)
Price (currency)
etc.....
ReservationID (autonum)
tblCottage (list of cottages available for rental)
cottage (text)
CottageID (autonum)
I need to add a table structure which defines the price band for each cottage at several times throughout the year, in order to take account of peak holiday periods etc. The price field in the tblReservation table needs to refer to the correct price band based on the cottage and the start date of the reservation.
Any thoughts how best to approach this would be greatly appreciated.
Many thanks
Chris

I am not sure if the vol_link_rol and vol_link_sta are correct, I have created a PK to ensure there is a record of the volunteer and the status and the same for the roles table.
comments please.

I have been asked to create a simple 5 question quiz and can not for the life of me figure out the table and form design. The goal is to have a question listed and then 5 answers to choose from. I need the answers to be in an options control format meaning they will read the question and check one of the option boxes for their choice. I need it allow only one of the 5 to be chosen...that is the problem. If I make each answer a field then they can check all of them and I don't want that. I don't think this is that difficult but would like to stay away from coding it as I am very good in access except for the code part.
Thanks in adavance!
