479 # The following tests check that NULL is handled correctly when it
480 # appears as part of a set of values on the right-hand side of an
481 # IN or NOT IN operator.
483 # When it appears in such a set, NULL is handled as an "unknown value".
484 # If, because of the unknown value in the set, the result of the expression
485 # cannot be determined, then it itself evaluates to NULL.
488 # Warm body test to demonstrate the principles being tested:
493 1 IN (NULL, 1, 2), -- The value 1 is a member of the set, return true.
494 3 IN (NULL, 1, 2), -- Ambiguous, return NULL.
495 1 NOT IN (NULL, 1, 2), -- The value 1 is a member of the set, return false.
496 3 NOT IN (NULL, 1, 2) -- Ambiguous, return NULL.
