Adrian,
That makes sense: the statements are treated as comments. I hadn't thought
of them that way.

Here's a template:
update contacts
set
where
;
The contacts table has these attributes:
person_nbr | integer
act_date | date
act_type | character varying(12)
notes | text
next_contact | date
Could be a changed next_contact date, or notes, or both.
Other tables need updating; for example, a new job title for a person or a
new web site for a company.
Thanks,
Rich
