Can I pass in a list or some other type, I have over 30 columns?
a=session.execute("assp_ReportDailyTransactions @start_date=:start,
@end_date=:end",params={'start':"20100701",'end':"20100719"})
b=session.query(a.keys()).from_statement("exec
assp_ReportDailyTransactions @start_date=:start,
@end_date=:end").params({'start':"20100701",'end':"20100719"}).all()
