    Using lookup data for table 1 mutible times in table 2

    Hi everybody.
    I'm an access beginner trying to make a simple data base to help me plan and produce concerts.

    A short description of the problem in my project is as follows.

    I have table employe_data containing info of employes data: name, mobile, email.

    Table concert_data contains details of the concerts i'm planning: eg, artist, date, time etc.

    In table concertd_data i would like to do multible lookups in different fields to table employe_data to assign employes a various task in the concert:

    concert_artist
    concert_date


    concert_time
    booking_responsible look up into table a getting name, mobile, mail off person a
    production_responsible look up into table a getting name, mobile, mail off person b

    This works great for 1 person only with a many to one relationship from table concerts (many) to table employe (on), but person b's data never arrives.

    So in short my problem is that I want many fields to look up data in the same table and return info for the various look ups.

    this might be a beginner problem, but hey... thats what i am ;-)

    Any ideas of a proper design?

    greetings

    Welcome to the forum!

    Since you have many tasks related to a concert, you have a one-to-many relationship which requires a separate but related task table to hold the assignments.

    employe_data
    -pkEmployeeID primary key, autonumber
    -empname (the word name is a reserved word in Access, so you should use a different field name)
    -mobile
    -email

    concert_data
    -pkConcertDataID primary key, autonumber
    -concert_artist
    -concert_datetime

    By the way can an artist have many concert dates?

    concert_dataAssignments
    -pkCDAssignID primary key, autonumber
    -fkConcertDataID foreign key to concert_data table; all foreign key fields must be a long integer number datatype field to match that of the related autonumber field
    -fkEmpID foreign key to employe_data table
    -fkAssignmentID foreign key to tblAssignments

    tblAssignments (a table that just holds a list of all possible assignments)
    -pkAssignmentID primary key, autonumber
    -txtAssignment

    The tables will only store the foreign key data, if you want to see additional details you would use a query that brings the related tables together and you would select the fields you would want to see.

    Similar problem

    I have a similar problem, and have set up your database structure, and it all seems to work good.

    Is it possible to make records for the default tasks automatically when creating a new item(project in my case), so that when you make a new project you create one record for each possible task with an unassigned field. So that when you go to a form to edit the project you have a subform with the 3 default tasks ready to be just edited, rather than having to create records for each task.

    I hope that makes sense, I am probably missing the point entirely.

    Yes, what you describe is possible. You will have to define those tasks as default tasks in some way. Assuming that you have a table that has all possible tasks, you can add a field such as a yes/no field and if checked, it would be a default task. It will take some Visual Basic for Application (VBA) code to accomplish what you want. I've attached an example database.

    Just thought I'd mention that there is a free data model here that might be useful -- at least some ideas. may be overkill, but some features may be worth noting.
