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') RETURNING id), '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? Regards, Cliff -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
