[GENERAL] how to list or array of key value pairs

[J.V.]

I need to rephrase this because of some confusion as to what I was 
looking for.

I want to create and initialize a list or array of key/value pairs.  
Then I want to iterate through this list (or array) retrieving each 
key/value for use in a sql statement.

I want to do this in a stored function.

that's all

any ideas?

J.V.
