This is a really trivial question, but I'm curious. Why do
subselects in target lists behave differently than simple queries?
Ex:
[lexus] create temporary table bar (key varchar(32) not null);
CREATE TABLE
[lexus] insert into bar select '';
INSERT 1319585 1
[lexus] insert into bar select (select '') as key;
ERROR: failed to find conversion function from "unknown" to
character varying
[lexus] insert into bar select (select ''::text) as key;
INSERT 1319586 1
Just curious,
Mike Mascari
