Hello everyone, Take this for example: ```SQL CREATE TABLE t0(c0 PRIMARY KEY); INSERT INTO t0(c0) VALUES (0); SELECT * FROM t0 WHERE (c0 NOT NULL) OR (c0 == NULL); ``` The expected output is 0, and yes, the output is exactly 0. But when adding a constant term "AND 1" to the term "c0 NOT NULL", the SQLite will get incorrect output: ```SQL SELECT * FROM t0 WHERE ((c0 NOT NULL) AND 1) OR (c0 == NULL); ``` Nothing will be printed. I wonder whether it is a bug. Looking forward to your early reply :)
