I've got a pickerview.
I would like to call a specific function each time the list changes (an item is added or removed).
How would I be able to do that ? I have tried a few IB Actions but could not get the function triggered.

I often see a pattern used in circumstances where we have look-up code that needs to be executed before we have access to an object. When using this pattern, usually begins with the word `with`.
For example, we have customer records that need to be retrieved from a database before we can use them:

This is the Strategy pattern. The closure holds some piece of behavior to be passed into the function as an argument, so that the function can accept different behaviors. See Peter Norvig's presentation [Design Patterns in Dynamic Languages](http://norvig.com/design-patterns/ppframe.htm):

I've always found SQL Server date formatting to be counter intuitive. I am pretty sure I already know the only answer is to use a slew of convert and string functions but thought I would ask just in case.
How do you get SQL Server to format a `datetime` to look like:

%Y-%m-%d %I:%M%P or '2012-04-05 11:56am'
