Access - Calculate value of a field based on value of another in the same table

Greetings Experts,

I have a table ('user') with the following structure:

ID (pk), Name, Age, EnctrCnt

I am trying to figure out a way (vba, query, view, new table, etc.) to calculate a weighted score based on the value of EnctrCnt.  

For the weights, if the user's encounter count is between 1-3 they get 3 points for each encounter, between 4-10 they get 5 points for each encounter, and for >10 they get 7 points for each encounter.  

I have tried doing this in a report and form using if statements.  The report didn't work and the form only worked if I clicked through each record using the On Load event.  I tried the On Open but nothing happened.

I have basic SQL and VBA knowledge so I am struggling with what is and is not allowed in Access.  

I am using Access 2013

Please let me know if you have any questions.

it would be more easier and dynamic for calculation if you have an encounter point table to store the points to be allocated for your range of encountered values

I am fine with creating another table but I need assistance in how to calculate the values using SQL, VBA, or any other method.  Since the values are limitless I was leaning towards a loop but don't know how they are constructed in VBA or SQL. It would be easy for me to do in PHP but unfortunately  that is not an option because this is a system at work.

once you have 2 tables you can construct the relevant SQL to generate the output you needed.

I think this can be done.

will you want to go with database option?

Hi.

If the ranges are fixed, you can use the IIF function, is easy and quick.

The SQL code could be:

SELECT ID, Name, Age, EnctrCnt, IIf([EnctrCnt]<=3,3,IIf([EnctrCnt]>3 And [EnctrCnt]<10,5,7)) AS Points
FROM [user];

Open in new window



Other way is to use the Partition function, but the ranges are determined by the function parameters.

You can find more info about the Partition Function here Partition function
