CREATE TABLE aa
(
a_col1 text
);
CREATE TABLE bb
(
b_col1 text
);
This update works:
UPDATE bb
SET b_col1 = aa.a_col1
FROM aa
WHERE bb.b_col1 <> aa.a_col1;
This does not:
UPDATE bb
SET bb.b_col1 = aa.a_col1
FROM aa
WHERE bb.b_col1 <> aa.a_col1;
Error: column "bb" of relation "bb" does not exist.
postgres 8.1.2
Maybe in a future version the alias can be allowed? Perhaps someone wanted to
avoid updating the wrong column on accident and put this in as a safety net?
