Update Calculated [Field] Base on the status of a Separate Table - ms-access

Question

I need to change the value of a Calculated FIELD depending on the results from a separate table.
I made up a small Fake DB(attached) to highlight my problem..
When the Database is open I want to be able to show on the first screen if ALL training is up to date for each employee, by changing the value of the "Calculated Field".
I have 5 Employees.
Each Employees must do 5(or more) training's.
All Training's must NOT be expired.
If a single training is expired Change Calculated Field Value to "NO GOOD"
If ALL training is NOT expired Change Calculated Field Value to "ALL GOOD"
I have no Idea on how to approach this scenario. Do I need to create a separate "Temp Table" to store this value?
Database found HERE: http://1drv.ms/1tX7L9M
I can't link pictures or more than 2 links yet so please look at these:
http://1drv.ms/1tXhr45
Here is my query.
SELECT Training.ID, Training.EmployeeID, Employees.Name, Training.TrainingID, Training.TrainingDate, TrainingList.Frequency, DateAdd("m",[frequency],[TrainingDate]) AS DueDate
FROM Employees INNER JOIN (Training INNER JOIN TrainingList ON Training.TrainingID = TrainingList.TrainingID) ON Employees.EmployeeID = Training.EmployeeID;
I need to check that all training for each Employee is current. If it is then I need to show this by changing the value from my first form.. The record source of the first form is like this:
SELECT DISTINCTROW Employees.ID, Employees.Name, Employees.EmployeeID, "Help With This Field" AS TrainingStatus
FROM Employees;
The Purpose of this is to make my life easier and be able to see at a glance which employees need to do recurrent training and which are up to date.. I still can't visualized how this can be done.. I am a (Google is my teacher kind of access user :( )

Answer 1

You have a query which computes the DueDate for all training records. Use it as the data source for another query in which you restrict the results to only those records whose DueDate has not already passed.
SELECT tq.*
FROM [Training Query] AS tq
WHERE (((tq.DueDate)>=Date()));
If that query returns the correct records --- only those trainings which have not expired --- reuse its WHERE clause in a GROUP BY query where you count up the number of unexpired trainings per each employee.
SELECT tq.EmployeeID, Count(tq.TrainingID) AS CountOfTrainingID
FROM [Training Query] AS tq
WHERE (((tq.DueDate)>=Date()))
GROUP BY tq.EmployeeID;
If that query also produces sane results, you can use an IIf expression to return "ALL GOOD" when CountOfTrainingID >= 5 and "NO GOOD" when it's < 5.
SELECT
sub.EmployeeID,
sub.CountOfTrainingID,
IIf(
sub.CountOfTrainingID >= 5,
'ALL GOOD',
'NO GOOD'
) AS TrainingStatus
FROM
(
SELECT tq.EmployeeID, Count(tq.TrainingID) AS CountOfTrainingID
FROM [Training Query] AS tq
WHERE (((tq.DueDate)>=Date()))
GROUP BY tq.EmployeeID
) AS sub;
That should get you most of the way to your goal. You would still need to join in the Employees table to get their names.
There may be other issues which you still need to address:
If an employee has not yet completed any trainings, or all his trainings have expired, should his name appear in the query (and form based on that query)?
Is your criteria based on 5 or more different trainings? For example, if an employee completed only the same training 5 times in the past month, should his TrainingStatus be good or no good?
