Ответ на What is the syntax for UPDATE from one table to another?  (pw <p.willis@telus.net>)

Thanks to everyone who helped.
I found the solution just by tooling with the SQL syntax.

FYI,  the correct syntax is:


UPDATE destination_table SET dest_column=A FROM
(SELECT src_column as A, src_link_col FROM src_table) AS  J
WHERE src_link_col=dst_link_col;
