Hashjoin's hashkeys need to reference its outer plan, Hash's --- need to reference Hash's outer plan (which is below HashJoin's --- inner plan). It's not trivial to verify that the references are --- correct (we don't display the hashkeys themselves), but if the --- hashkeys contain subplan references, those will be displayed. Force --- subplans to appear just about everywhere. --- --- Bug report: --- https://www.postgresql.org/message-id/CAPpHfdvGVegF_TKKRiBrSmatJL2dR9uwFCuR%2BteQ_8tEXU8mxg%40mail.gmail.com --- -BEGIN; -SET LOCAL enable_sort = OFF; -- avoid mergejoins -SET LOCAL from_collapse_limit = 1; -- allows easy changing of join order -CREATE TABLE hjtest_1 (a text, b int, id int, c bool); -CREATE TABLE hjtest_2 (a bool, id int, b text, c int); -INSERT INTO hjtest_1(a, b, id, c) VALUES ('text', 2, 1, false); -- matches -INSERT INTO hjtest_1(a, b, id, c) VALUES ('text', 1, 2, false); -- fails id join condition -INSERT INTO hjtest_1(a, b, id, c) VALUES ('text', 20, 1, false); -- fails < 50 -INSERT INTO hjtest_1(a, b, id, c) VALUES ('text', 1, 1, false); -- fails (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) -INSERT INTO hjtest_2(a, id, b, c) VALUES (true, 1, 'another', 2); -- matches -INSERT INTO hjtest_2(a, id, b, c) VALUES (true, 3, 'another', 7); -- fails id join condition -INSERT INTO hjtest_2(a, id, b, c) VALUES (true, 1, 'another', 90); -- fails < 55 -INSERT INTO hjtest_2(a, id, b, c) VALUES (true, 1, 'another', 3); -- fails (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) -INSERT INTO hjtest_2(a, id, b, c) VALUES (true, 1, 'text', 1); -- fails hjtest_1.a <> hjtest_2.b; -EXPLAIN (COSTS OFF, VERBOSE) -SELECT hjtest_1.a a1, hjtest_2.a a2,hjtest_1.tableoid::regclass t1, hjtest_2.tableoid::regclass t2 -FROM hjtest_1, hjtest_2 -WHERE - hjtest_1.id = (SELECT 1 WHERE hjtest_2.id = 1) - AND (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) - AND (SELECT hjtest_1.b * 5) < 50 - AND (SELECT hjtest_2.c * 5) < 55 - AND hjtest_1.a <> hjtest_2.b; - QUERY PLAN ------------------------------------------------------------------------------------------------- - Hash Join - Output: hjtest_1.a, hjtest_2.a, (hjtest_1.tableoid)::regclass, (hjtest_2.tableoid)::regclass - Hash Cond: ((hjtest_1.id = (SubPlan 1)) AND ((SubPlan 2) = (SubPlan 3))) - Join Filter: (hjtest_1.a <> hjtest_2.b) - -> Seq Scan on public.hjtest_1 - Output: hjtest_1.a, hjtest_1.tableoid, hjtest_1.id, hjtest_1.b - Filter: ((SubPlan 4) < 50) - SubPlan 4 - -> Result - Output: (hjtest_1.b * 5) - -> Hash - Output: hjtest_2.a, hjtest_2.tableoid, hjtest_2.id, hjtest_2.c, hjtest_2.b - -> Seq Scan on public.hjtest_2 - Output: hjtest_2.a, hjtest_2.tableoid, hjtest_2.id, hjtest_2.c, hjtest_2.b - Filter: ((SubPlan 5) < 55) - SubPlan 5 - -> Result - Output: (hjtest_2.c * 5) - SubPlan 1 - -> Result - Output: 1 - One-Time Filter: (hjtest_2.id = 1) - SubPlan 3 - -> Result - Output: (hjtest_2.c * 5) - SubPlan 2 - -> Result - Output: (hjtest_1.b * 5) -(28 rows) - -SELECT hjtest_1.a a1, hjtest_2.a a2,hjtest_1.tableoid::regclass t1, hjtest_2.tableoid::regclass t2 -FROM hjtest_1, hjtest_2 -WHERE - hjtest_1.id = (SELECT 1 WHERE hjtest_2.id = 1) - AND (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) - AND (SELECT hjtest_1.b * 5) < 50 - AND (SELECT hjtest_2.c * 5) < 55 - AND hjtest_1.a <> hjtest_2.b; - a1 | a2 | t1 | t2 -------+----+----------+---------- - text | t | hjtest_1 | hjtest_2 -(1 row) - -EXPLAIN (COSTS OFF, VERBOSE) -SELECT hjtest_1.a a1, hjtest_2.a a2,hjtest_1.tableoid::regclass t1, hjtest_2.tableoid::regclass t2 -FROM hjtest_2, hjtest_1 -WHERE - hjtest_1.id = (SELECT 1 WHERE hjtest_2.id = 1) - AND (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) - AND (SELECT hjtest_1.b * 5) < 50 - AND (SELECT hjtest_2.c * 5) < 55 - AND hjtest_1.a <> hjtest_2.b; - QUERY PLAN ------------------------------------------------------------------------------------------------- - Hash Join - Output: hjtest_1.a, hjtest_2.a, (hjtest_1.tableoid)::regclass, (hjtest_2.tableoid)::regclass - Hash Cond: (((SubPlan 1) = hjtest_1.id) AND ((SubPlan 3) = (SubPlan 2))) - Join Filter: (hjtest_1.a <> hjtest_2.b) - -> Seq Scan on public.hjtest_2 - Output: hjtest_2.a, hjtest_2.tableoid, hjtest_2.id, hjtest_2.c, hjtest_2.b - Filter: ((SubPlan 5) < 55) - SubPlan 5 - -> Result - Output: (hjtest_2.c * 5) - -> Hash - Output: hjtest_1.a, hjtest_1.tableoid, hjtest_1.id, hjtest_1.b - -> Seq Scan on public.hjtest_1 - Output: hjtest_1.a, hjtest_1.tableoid, hjtest_1.id, hjtest_1.b - Filter: ((SubPlan 4) < 50) - SubPlan 4 - -> Result - Output: (hjtest_1.b * 5) - SubPlan 2 - -> Result - Output: (hjtest_1.b * 5) - SubPlan 1 - -> Result - Output: 1 - One-Time Filter: (hjtest_2.id = 1) - SubPlan 3 - -> Result - Output: (hjtest_2.c * 5) -(28 rows) - -SELECT hjtest_1.a a1, hjtest_2.a a2,hjtest_1.tableoid::regclass t1, hjtest_2.tableoid::regclass t2 -FROM hjtest_2, hjtest_1 -WHERE - hjtest_1.id = (SELECT 1 WHERE hjtest_2.id = 1) - AND (SELECT hjtest_1.b * 5) = (SELECT hjtest_2.c*5) - AND (SELECT hjtest_1.b * 5) < 50 - AND (SELECT hjtest_2.c * 5) < 55 - AND hjtest_1.a <> hjtest_2.b; - a1 | a2 | t1 | t2 -------+----+----------+---------- - text | t | hjtest_1 | hjtest_2 -(1 row) - -ROLLBACK; --- Verify that we behave sanely when the inner hash keys contain parameters --- (that is, outer or lateral references).
