No. Some questions though.
Thanks for the reply Adrian.
What version pf Postgres?
9.1
Is that the actual UPDATE statement, I see no SET?
I was reading the docs but obviously don't understand the syntax of the
update statement.
Have you tried it?
If so and it failed what was the error?
Yes and I got an error at or near from. Like this:
b4warmed3=# UPDATE sixty_min FROM tmp_60 WHERE sixty_min.rowid =
tmp_60.rowid;
ERROR: syntax error at or near "FROM"
LINE 1: UPDATE sixty_min FROM tmp_60 WHERE sixty_min.rowid = tmp_60....
^
b4warmed3=#
It is not enough to match the rows through "sixty_min.rowid = tmp_60."
You also need to match the columns using SET.
Per the examples at the bottom of:
http://www.postgresql.org/docs/9.2/interactive/sql-update.html
UPDATE employees SET sales_count = sales_count + 1 FROM accounts
WHERE accounts.name = 'Acme Corporation'
AND employees.id = accounts.sales_person;
For many columns it is easier to use the other form of SET. Example from
docs:
UPDATE weather SET (temp_lo, temp_hi, prcp) = (temp_lo+1, temp_lo+15,
DEFAULT)
