SQLSoup results and zip

Hi All
I've taken the plunge and have started porting my database stuff to  
sqlsoup
A problem i've encountered is that sometimes i need to get a "column"  
from a list or results
so i do  a res=zip(*mycur.fetchall()) and res[0] is the first column  
etc.
How do i replicate this in SQLSoup?
when i try   for example
res=mydb.intraday.select(mydb.intraday.c.symbol=='RBTT',
                                      order_by=[desc 
(mydb.intraday.c.trade_date)])
zip(*res)  i get
TypeError: zip argument #1 must support iteration
Regards
Chris
