Re: Calculating fields

Two possibilities:
1) Calculate the points as the data is stored in the table - for that you'll need a trigger that fires on an insert, do the calculation in that trigger and store the result. This is a good option of the formula never [ever] changes.
2) Calculate the points as the data is retrieved - for that you'll want a view that includes a calculated column that derives the points based on other values in the row.

Which option you go for is entirely up to you (and whether you can translate Excel-ese into MySQL's DML syntax!).
