I was doing some experimenting and was wondering why the following does
not work:
CREATE TABLE accounts ( id SERIAL PRIMARY KEY NOT NULL, accounts_id INTEGER REFERENCES accounts, name TEXT
);
INSERT INTO accounts (accounts_id, name) VALUES ( (INSERT INTO accounts (accounts_id, name) VALUES (NULL, 'test 1')
RETURNINGid), 'test 2');
ERROR: syntax error at or near "INTO"
Of course, the following works fine:
INSERT INTO accounts (accounts_id, name) VALUES (NULL, 'test 1');
INSERT INTO accounts (accounts_id, name) VALUES ( (SELECT id FROM accounts WHERE name='test 1'), 'test 2');
As far as I can see, INSERT INTO...RETURNING is semantically equivalent
to SELECT...FROM with a side-effect, so it seems this construct should
work. Can someone shed some light?
