Problem:
--------
SELECT * FROM <view> returns following error message:
ERROR: replace_vars_with_subplan_refs: variable not in subplan target list
Environment:
------------
Version: PostgreSQL 7.2 on i686-pc-linux-gnu, compiled by GCC 2.95.2
System: Linux jtam.brno.czechin.cz 2.2.17-RAID #8 SMP Mon Oct 16 10:48:13
CEST 2000 i686 unknown
Exact steps to reproduce this bug:
----------------------------
CREATE TABLE "fs_ucastnici" (
"id" integer DEFAULT nextval('"fs_ucastnici_id_seq"'::text) NOT
NULL,
"jmeno" character varying(50),
"email" character varying(40),
Constraint "fs_ucastnici_pkey" Primary Key ("id")
);
CREATE SEQUENCE "fs_ucastnici_id_seq" start 1 increment 1 maxvalue
2147483647 minvalue 1 cache 1;
CREATE TABLE "userdb" (
"username" character varying(16) NOT NULL,
"email" text,
"name" character varying(80)
);
CREATE UNIQUE INDEX userdb_pkey ON userdb USING btree (username);
CREATE TABLE "emaily" (
"email" text NOT NULL,
"jmeno" text,
"akce" character varying(40) NOT NULL,
Constraint "emaily_pkey" Primary Key ("email")
);
CREATE VIEW "infomail" as
SELECT DISTINCT ON (lower(vsichni.email)) vsichni.email,
vsichni.jmeno, vsichni.id, vsichni.odkud FROM (
SELECT fs_ucastnici.email, fs_ucastnici.jmeno,
fs_ucastnici.id::text AS id, 'soutez' AS odkud FROM ONLY fs_ucastnici
UNION
SELECT userdb.email, userdb.name, (userdb.username)::text AS
username, 'userdb' FROM ONLY userdb
UNION
SELECT emaily.email, emaily.jmeno, ''::text, 'emaily'
FROM ONLY emaily WHERE (emaily.akce = 'add')
) vsichni
WHERE (vsichni.email ~ '@'::text)
ORDER BY lower(vsichni.email);
When this schema exists, try:
SELECT * FROM infomail;
On my system, it fails with "ERROR: replace_vars_with_subplan_refs:
variable not in subplan target list".
