Consider the following test case:
CREATE TABLE t0(c0 TEXT PRIMARY KEY);
INSERT INTO t0(c0) VALUES ('');
SELECT * FROM t0 WHERE (t0.c0, TRUE) > (CAST('' AS REAL), FALSE); -- unexpected: row is not fetched
Unexpectedly, the row is not fetched, although the WHERE clause seems to evaluate to TRUE: SELECT (t0.c0, TRUE) > (CAST(0 AS REAL), FALSE) FROM t0; -- 1 | ||||
