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. 16 # 17 18 set testdir [file dirname $argv0] 19 source $testdir/tester.tcl 20 source $testdir/lock_common.tcl 21 source $testdir/malloc_common.tcl 22 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. 36 # 37 do_execsql_test tkt-80e031a00f.1 {SELECT 1 IN ()} 0 38 do_execsql_test tkt-80e031a00f.1b {SELECT 1 IN (2)} 0 39 do_execsql_test tkt-80e031a00f.1c {SELECT 1 IN (2,3,4,5,6,7,8,9)} 0 40 do_execsql_test tkt-80e031a00f.2 {SELECT 1 NOT IN ()} 1 41 do_execsql_test tkt-80e031a00f.2b {SELECT 1 NOT IN (2)} 1 42 do_execsql_test tkt-80e031a00f.2c {SELECT 1 NOT IN (2,3,4,5,6,7,8,9)} 1 43 do_execsql_test tkt-80e031a00f.3 {SELECT null IN ()} 0 44 do_execsql_test tkt-80e031a00f.4 {SELECT null NOT IN ()} 1 45 do_execsql_test tkt-80e031a00f.5 { 46 CREATE TABLE t1(x); 47 SELECT 1 IN t1; 48 } 0 49 do_execsql_test tkt-80e031a00f.6 {SELECT 1 NOT IN t1} 1 50 do_execsql_test tkt-80e031a00f.7 {SELECT null IN t1} 0 51 do_execsql_test tkt-80e031a00f.8 {SELECT null NOT IN t1} 1 52 do_execsql_test tkt-80e031a00f.9 { 53 CREATE TABLE t2(y INTEGER PRIMARY KEY); 54 SELECT 1 IN t2; 55 } 0 56 do_execsql_test tkt-80e031a00f.10 {SELECT 1 NOT IN t2} 1 57 do_execsql_test tkt-80e031a00f.11 {SELECT null IN t2} 0 58 do_execsql_test tkt-80e031a00f.12 {SELECT null NOT IN t2} 1 59 do_execsql_test tkt-80e031a00f.13 { 60 CREATE TABLE t3(z INT UNIQUE); 61 SELECT 1 IN t3; 62 } 0 63 do_execsql_test tkt-80e031a00f.14 {SELECT 1 NOT IN t3} 1 64 do_execsql_test tkt-80e031a00f.15 {SELECT null IN t3} 0 65 do_execsql_test tkt-80e031a00f.16 {SELECT null NOT IN t3} 1 66 do_execsql_test tkt-80e031a00f.17 {SELECT 1 IN (SELECT x+y FROM t1, t2)} 0 67 do_execsql_test tkt-80e031a00f.18 {SELECT 1 NOT IN (SELECT x+y FROM t1,t2)} 1 68 do_execsql_test tkt-80e031a00f.19 {SELECT null IN (SELECT x+y FROM t1,t2)} 0 69 do_execsql_test tkt-80e031a00f.20 {SELECT null NOT IN (SELECT x+y FROM t1,t2)} 1 70 do_execsql_test tkt-80e031a00f.21 {SELECT 1.23 IN ()} 0 71 do_execsql_test tkt-80e031a00f.22 {SELECT 1.23 NOT IN ()} 1 72 do_execsql_test tkt-80e031a00f.23 {SELECT 1.23 IN t1} 0 73 do_execsql_test tkt-80e031a00f.24 {SELECT 1.23 NOT IN t1} 1 74 do_execsql_test tkt-80e031a00f.25 {SELECT 'hello' IN ()} 0 75 do_execsql_test tkt-80e031a00f.26 {SELECT 'hello' NOT IN ()} 1 76 do_execsql_test tkt-80e031a00f.27 {SELECT 'hello' IN t1} 0 77 do_execsql_test tkt-80e031a00f.28 {SELECT 'hello' NOT IN t1} 1 78 do_execsql_test tkt-80e031a00f.29 {SELECT x'303132' IN ()} 0 79 do_execsql_test tkt-80e031a00f.30 {SELECT x'303132' NOT IN ()} 1 80 do_execsql_test tkt-80e031a00f.31 {SELECT x'303132' IN t1} 0 81 do_execsql_test tkt-80e031a00f.32 {SELECT x'303132' NOT IN t1} 1 82 83 #
