Question

I use the following columns stored in a SQL table called tb_player:

Date of Birth (Date), Times Played (Integer), Versions (Integer)

to calculate a ‘playvalue’ (integer) in the following formula:

playvalue = (Today - Date of Birth) * Times Played * Versions 

I display upto 100 of these records with the associataed playvalue on a webpage at any time.

My question is, what is the most efficient way of calculating this playvalue given it will change only once a day, due to the (today-date of birth) changing? The other values (times played & versions) remain the same.

Is there a better way than calculating this on the fly each time for the 100 records? If so, is it more efficient to do the calculation in a stored proc or in VB.NET/C#?

Answer 1

In a property/method on the object, in C#/VB.NET (your .NET code).

The time to execute a simple property like this is nothing compared to the time to call out-of-process to a database (to fetch the rows in the first place), or the transport time of a web-page; you’ll never notice it if just using it for UI display. Plus it is on your easily-scaled-out hardware (the app server), and doesn’t involve a huge update daily, and is only executed for rows that are actually displayed, and only if you actually query this property/method.
