# EVIDENCE-OF: R-58875-56087 The IN and NOT IN operators take a single # scalar operand on the left and a vector operand on the right formed by # an explicit list of zero or more scalars or by a single subquery. # # 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 # skipif oracle statement ok CREATE TABLE t1( x INTEGER, y TEXT ) onlyif oracle statement ok CREATE TABLE t1( x INTEGER, y VARCHAR(8) ) statement ok INSERT INTO t1 VALUES(1,'true') statement ok INSERT INTO t1 VALUES(0,'false') statement ok INSERT INTO t1 VALUES(NULL,'NULL') # Row 1: query I nosort SELECT 1 FROM t1 WHERE 1 IN (2) ---- query I nosort SELECT 1 FROM t1 WHERE 1.0 IN (2.0) ---- query I nosort SELECT 1 FROM t1 WHERE '1' IN ('2') ---- query I nosort SELECT 1 FROM t1 WHERE 1 NOT IN (2) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE 1.0 NOT IN (2.0) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE '1' NOT IN ('2') ---- 1 1 1 # # Row 2: empty RHS skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE 1 IN () ---- skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE 1.0 IN () ---- skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE '1' IN () ---- skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE NULL IN () ---- skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE 1 NOT IN () ---- 1 1 1 skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE 1.0 NOT IN () ---- 1 1 1 skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE '1' NOT IN () ---- 1 1 1 skipif mysql # empty RHS skipif mssql # empty RHS skipif oracle # empty RHS query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN () ---- 1 1 1 # Row 3: query I nosort SELECT 1 FROM t1 WHERE 1 IN ( NULL, 1 ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE 1.0 IN ( NULL, 1.0 ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE '1' IN ( NULL, '1' ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE 1 NOT IN ( NULL, 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE 1.0 NOT IN ( NULL, 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE '1' NOT IN ( NULL, '1' ) ---- query I nosort SELECT 1 FROM t1 WHERE 1 IN ( 1 ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE 1.0 IN ( 1.0 ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE '1' IN ( '1' ) ---- 1 1 1 query I nosort SELECT 1 FROM t1 WHERE 1 NOT IN ( 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE 1.0 NOT IN ( 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE '1' NOT IN ( '1' ) ---- # # Row 4: RHS contains NULL, LHS not in RHS query I nosort SELECT 1 FROM t1 WHERE 1 IN ( NULL, 2 ) ---- query I nosort SELECT 1 FROM t1 WHERE 1.0 IN ( NULL, 2.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE '1' IN ( NULL, '2' ) ---- query I nosort SELECT 1 FROM t1 WHERE 1 NOT IN ( NULL, 2 ) ---- query I nosort SELECT 1 FROM t1 WHERE 1.0 NOT IN ( NULL, 2.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE '1' NOT IN ( NULL, '2' ) ---- # # Row 5: LHS is NULL query I nosort SELECT 1 FROM t1 WHERE NULL IN ( 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL IN ( 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL IN ( '1' ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( '1' ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL IN ( NULL, 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL IN ( NULL, 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL IN ( NULL, '1' ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( NULL, 1 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( NULL, 1.0 ) ---- query I nosort SELECT 1 FROM t1 WHERE NULL NOT IN ( NULL, '1' ) ---- |
