[DB-SIG] dbi date

[jeff at jdfiles.org]

I'm working on a project where I extract data from one database and insert it 
into another. I have created functions to scrub the individual fields in 
various ways depending on the field type. I pull in the entire result set, 
then  iterate over each row and column in turn I want to call the correct 
function for each type as it is found. The problem is that dbi.date is not a 
type, but an object. How can I build a select/case-style block that includes 
both objects and types ?
