For the following test case, the row inserted into the table is not fetched by the subsequent query: CREATE TABLE t0(c0); CREATE TABLE t1(c0); CREATE VIEW v0(c0) AS SELECT t0.c0 FROM t1 LEFT JOIN t0; INSERT INTO t1(c0) VALUES (0); SELECT * FROM v0 WHERE (v0.c0, x'') != (NULL, 0); -- unexpected: row is not fetched I would expect the row to be fetched, since the comparison evaluates to TRUE: SELECT (v0.c0, x'') != (NULL, 0) FROM v0; -- TRUE |
