Bug reference: 7926
Logged by: Jakub Kania
Email address: jakubka...@onet.pl
PostgreSQL version: 9.1.4
Operating system: Windows 7
Description:
I'm not really sure what is going on but I was advised on the IRC chanell to
report it.
I get the error:
ERROR: recursive query "bank" column 2 has type numeric(20,2) in
non-recursive term but type numeric overall
LINE 6: SELECT ARRAY[id],amount::numeric(20,2) FROM bank_transacti...
^
HINT: Cast the output of the non-recursive term to the correct type.
********** Error **********
ERROR: recursive query "bank" column 2 has type numeric(20,2) in
non-recursive term but type numeric overall
SQL state: 42804
Hint: Cast the output of the non-recursive term to the correct type.
Character: 140
WITH RECURSIVE bank(id,amount) AS (
SELECT ARRAY[id],amount::numeric(20,2) FROM bank_transactions
UNION ALL
SELECT b1.id||ARRAY[borg.id],b1.amount+borg.amount
FROM bank AS b1 LEFT JOIN
bank_transactions AS borg ON borg.id>ALL(b1.id)
)
SELECT * from bank LIMIT 100;
With schema:
CREATE TABLE bank_transactions
(
id serial NOT NULL,
amount numeric(20,2),
CONSTRAINT bank_transactions_pkey PRIMARY KEY (id )
)
Casting the column the error is pointing too doesn't help at all, casting
the one in the other select fixes it.
