Adrian,
That makes sense: the statements are treated as comments. I hadn't thought
of them that way.
2) How do I write a cursor execute UPDATE statement where the columns and
values to be updated can be single or multiple and the values passed into
the method from the tkinter widgets? Are there examples from which I can
learn?
There are several ways to read the above.
Send some examples of what you want to do.
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
