13 # resolved. That ticket is about IN and NOT IN operators with empty-set
14 # right-hand sides. Such expressions should always return TRUE or FALSE
15 # even if the left-hand side is NULL.

23 # EVIDENCE-OF: R-52275-55503 When the right operand is an empty set, the
24 # result of IN is false and the result of NOT IN is true, regardless of
25 # the left operand and even if the left operand is NULL.
27 # EVIDENCE-OF: R-64309-54027 Note that SQLite allows the parenthesized
28 # list of scalar values on the right-hand side of an IN or NOT IN
29 # operator to be an empty list but most other SQL database engines and
30 # the SQL92 standard require the list to contain at least one element.
