Hi all,
Hi, I'm currently working as a graduate within a computer company and have been asked to create a database that will hold information concerning a traceability matrix. I have created the outlines of a relational db, but have a little problem.
Within a recent meeting i have been asked to provide the facilty for the user of the db to be able to search for records, according to different conditions. So my idea is to provide the user with a text field box(search criteria) and then display the result in a subform. I assume the information that will populate the subform will come from a query, based on the criteria provided.
Is there a tutorial or example of how do do this?Do you kow a better way of be doing this. If you would like more information concerning teh db please ask.
Thanks.

I would filter the main form according to the criteria entered. That would be a lot easier.

Hi Kelvin
Welcome to Utter Access Forums

according to different conditions.
Base on the above statement this article would be a good starting point..
How to use the Query by Form (QBF) technique in Access .
QUOTE
SUMMARY
This article shows you how to use a form to specify the criteria for a query. This technique is called query by form (QBF).
Back to the top
MORE INFORMATION
In the QBF technique, you create a form in which you enter query criteria. This form contains blank text boxes. Each text box represents a field in a table that you want to query. You make entries only in the text boxes for which you want to specify search criteria.
The QBF form resembles a data entry form that has fields that match the fields in a table. A table that has fields for Name, Address, City, State, and Zip Code can have a QBF form that has corresponding fields. To select certain records, you can enter any combination of search criteria in the form. You can specify a city only, or a city and a state, or a zip code only, or any other combination. Fields that you leave blank are ignored. When you click a command button on the form, Access runs a query that uses the search criteria from your form.

Larry, thank you for your welcome and thanks for the link.
I understand and have implemented that link inot the db, however how do i get the information produced by qbf to populate a subform instead of appearing in a popup window?
Thanks again.

Hi Kelvin
Your subform should be based on a query and you apply those filtering instructions from the link to filter out your data, here is another link to a working example and code on how to implement a search form/subform.

Check it out.

Sorry poor explaining.
BG info:
I have a table holding Requirement info, and a table holding usecase info.(M-2-m relationship)So i create a assign usecase table.
What i want to do is, search for a requirement and then display the requirement and the associated usecases.
Did i explan that better?

Hi
Would you have a junction table between Requirement and usecase.. tables.
eg:
tblRequirement >> jtblRegUseCase << tblUsecase

Thats what i have got. But how do you collect this information and display it in teh following way:
Requirement 1
Usecase 1
Usecase 2
...
Thanks again,

HI
Using a select query that has all three tables as it source..
The junction table should hold all instances of a requirement and usecase that are brought together as a single record under a unique id in the junction table.

How is everyone today??
I have used a query to produce details for a report, however i have one problem. The report produces a list list of requirements and their associated useacses.
My problem is that if i create a report using the query, and then add another usecase , then it will not show up on teh report. IS there a way of updating a report before it is previewed.
Also i would like to create a report that details how many requirements i have, how many usecases i have etc, how do i do this?
Thanks again for your help.
