I've read both Section 8.5 of the on-line 8.2.4 docs, and the pertinent
sections of Douglas & Douglas, and I'm still not certain that I'm correctly
expressing the query I want. Please correct as needed.
From table (Permits) I want to identify those which expire within a
specified time from today. For example:
SELECT permit_nbr, title, date_issued, term,
process_time from Permits
WHERE (date_issued + term YEARS)
< (CURRENT_DATE + process_time MONTHS);
Should I use TODAY rather than CURRENT_DATE? Do I need to cast intervals
explicitly from seconds to days, months, or years?
