Consider the following test case:
CREATE TABLE t0(c0 COLLATE NOCASE, c1);
INSERT INTO t0 VALUES('a', 'A');
SELECT * FROM t0 WHERE (+ t0.c1, 1) >= (t0.c0, 1); -- expected: row is not fetched, actual: row is fetched
I would not expect the row to be fetched, because the expression should evaluate to TRUE: SELECT (+ t0.c1, 1) >= (t0.c0, 1) FROM t0; -- 0 mrigger added on 2019-10-22 10:43:16: It seems that the check-in did not fix this issue-I detected the same bug again, and can still reproduce the issue on the current trunk. | ||||
