hey
I am quite beginner in Access. I have a problem with data entry form.
In a form I want to put one question which will allow mulitple answer. I want to store this anwers in one column.
For example: i want to store the record that tell me that the article was about politics and sport. In the table I have the column: Information type. I want to record this both (politic and sport) elements into one column (information type). How can I do it?
When I chose the multi select option this column wasn't fulfilled.
Lets say i have a structure:
News Table:
- Title
- Information Type
- Source
-Source Type etc.
Information Type Table:
- Sport
- Politics
- Economics
In news table i want to have in information type: sport and politics together.
So that i can receive:
title ¦ politics,sport ¦ Le Figaro ¦ Newspaper
How to do it?

You are asking how to create a non-normalised table structure :-) In your own best interest, I'm not going to tell you how to do that! However, I will try to explain the reason, and method to correctly do what you want.
Your News table and your Information Type table have a Many to Many relationship. This means that one record in the News table can be related to any number of records in the Information Type table. Conversely, one record in the Information Type table can be related to any number of records in the News table.
Very well and good, you say, now what? The normal way to handle this is to create a third table that links to the two into two One to Many relationships. This table will be called something like NewsInfoType and will have three fields:
NewsInfoTypeID, AutoNumber Primary Key;
NewsID, Number, Foreign Key;
InfoTypeID, Number, Foreign Key.
(note that you do not list the NewsID or InfoTypeID fields in your current data structure, you will need to create them, or replace them with the field names of the field(s) you are using as the Primary Key, unique identifier in each table)

Scott

Ok thx :) i tried out sth...
but still i cannot do it :/ I think i am to stupid.
Ok so ...
I created that many to many relationship.
but is it ok if it is like that
InfoType: NewsInfo
ID 1-------------many InfoID NEWS
Information Type NewsID many------------1 ID
information type
source etc.
i created automatic form for the NEWS table and in information type option i put multi selecet. but then it doesnt record that info types (politics and sport) in the table. why?
Maybe I should change sth in tables?

Hi Greg,
I'm assuming that you have created the correct relationships in the relationships window.
Now you'll need to create a query that will display the information you want for each field. All three tables will be included in this query, and then you will base you form on this query, instead of a table.

Scott

Ok but how to make that in one field there will be sport and politics together (from that InfoType table)?

I'm assuming that you want to show these values concatenated into one text box control on your form?
If you don't mind my asking, why not use a continuous subform that shows each info type associated with the record you are working with on the main form?

Hey Scott,
I dont know how to create that as well :)
Actually at this level I would like to save this values, rather than showing them :)
And i read somewhere that i can do it via VB (but i have no idea about programming in VB). As you wrote, I want to show these values concatenated into one text box - in the "Info type" column i would like to obtain "sport , politics".
I read somewhere that i can use multi select option and then i can select couple of info types. but when i try to add record it doesnt save me the info type. it stays null. I read that there is a special VB code for that to work. Maybe do you know that?
I realize that my answer become quite unorganized but i was reading too much on the forums and now i am confused. :)

Greg
Hi Greg,
At this point, may I make a kindly suggestion? There are a number of books that are very handy references. The one I keep on my desk at all times is called 'Special Edition Using Microsoft Office Access 2003', published by QUE software. It's available fairly cheaply on Amazon.com.
The book will present the information you need to know to accomplish what you wish in a far more linear fashion than what you will find on the internet in any forum anywhere.
I suspect that most of your confusion comes from looking at too many different sources!

Scott
