Access ODBC connection and relations in MySQL

I have made a good connection from Access to a mySql database. I can put an Access form over a table in MySql, which gives me the opportunity to create, update, delete records in the MYSQL table perfectly. However the relations between the tables in the Mysql database are, if you look in the records, made by comma seperate values??

For example an employee can work in the building a to z. The actual buildings he is working in are written in the "building" field as i.e. A, D, G, Z. The tabel building contains the buildings details.

Is this the way Mysql is controlling relations or is this bad programming of the guy who made the (interactive) website (PHP) on top of this MSQ database ??
How can I tell Access that in this case a relation exists of an employee with building A,D,G,Z. Access sees only a field with comma seperate text??

With kind regards,

This sounds like a design choice by the creator of the database.  The alternative would be to have separate table to contain the relationships.

To get a recordset of the buildings each employee is related to, I'd do something like this:

SELECT BuildingTable.*, EmployeeTable.* FROM EmployeeTable INNER JOIN BuildingTable ON EmployeeTable.Building LIKE "*" & BuildingTable.ID & "*"

As I don't know the names of all the fields and tables involved this is only example SQL, but if you substitute the correct names it should work.
Replace:
'BuildingTable' with the name of the Buildings table
'EmployeeTable' with the name of the Employees table
'ID' with the name of the field in the Buildings table which contains the single letter code (A,B,C etc)

Hope this helps
