Hi,
Executing the following statements only returns records with num != NULL.
Is that the intended behavior?
CREATE TABLE yyy (num DECIMAL(7))
/
INSERT INTO yyy VALUES (NULL)
/
INSERT INTO yyy VALUES (1)
/
INSERT INTO yyy VALUES (5)
/
INSERT INTO yyy VALUES (NULL)
/
SELECT * FROM yyy WHERE
Hi,
Yes, this is how other databases work as well. The reason is that a
comparison with NULL results in NULL. And NOT NULL is also NULL. And NULL
means no match.
