SQL:
CREATE TABLE t1(c0 integer NOT NULL, c2 TEXT);
ALTER SESSION SET EXECUTOR_DEVICE='CPU';
SELECT*FROM t1 JOIN (SELECT ALL 0.42445757423087693FROM t1) AS sub0 ON true WHERE NOT (t1.c2) NOT IN (t1.c2, t1.c2);
Result:

Result:
Query execution failed because the query contains not supported self-join pattern. We suspect the query requires multiple left-deep join tree due to the join condition of the self-join and is not supported fornow. Please consider chaning the table orderin the FROM clause.
