11 # This file implements regression tests for SQLite library. Specifically,
12 # it tests that ticket [80e031a00f45dca877ed92b225209cfa09280f4f] has been
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-58875-56087 The IN and NOT IN operators take a single
24 # scalar operand on the left and a vector operand on the right formed by
25 # an explicit list of zero or more scalars or by a single subquery.
26 #
27 # EVIDENCE-OF: R-52275-55503 When the right operand is an empty set, the
28 # result of IN is false and the result of NOT IN is true, regardless of
29 # the left operand and even if the left operand is NULL.
30 #
31 # EVIDENCE-OF: R-13595-45863 Note that SQLite allows the parenthesized
32 # list of scalar values on the right-hand side of an IN or NOT IN
33 # operator to be an empty list but most other SQL database database
34 # engines and the SQL92 standard require the list to contain at least
35 # one element.
