# EVIDENCE-OF: R-52275-55503 When the right operand is an empty set, the
# result of IN is false and the result of NOT IN is true, regardless of
# the left operand and even if the left operand is NULL.
#

# EVIDENCE-OF: R-13595-45863 Note that SQLite allows the parenthesized
# list of scalar values on the right-hand side of an IN or NOT IN
# operator to be an empty list but most other SQL database database
# engines and the SQL92 standard require the list to contain at least
# one element.
#

# EVIDENCE-OF: R-50221-42915 The result of an IN or NOT IN operator is
# determined by the following matrix: Left operand is NULL Right operand
# contains NULL Right operand is an empty set Left operand found within
# right operand Result of IN operator Result of NOT IN operator no no no
# no false true does not matter no yes no false true no does not matter
# no yes true false no yes no no NULL NULL yes does not matter no does
# not matter NULL NULL
