# This file implements regression tests for SQLite library. Specifically,
|
||
|
|
# it tests that ticket [fc7bd6358f]:
|
||
|
|
#
|
||
|
|
# The following SQL yields an incorrect result (zero rows) in all
|
||
|
|
# versions of SQLite between 3.6.14 and 3.7.15.2:
|
||
|
|
#
|
||
|
|
# CREATE TABLE t(textid TEXT);
|
||
|
|
# INSERT INTO t VALUES('12');
|
||
|
|
# INSERT INTO t VALUES('34');
|
||
|
|
# CREATE TABLE i(intid INTEGER PRIMARY KEY);
|
||
|
|
# INSERT INTO i VALUES(12);
|
||
|
|
# INSERT INTO i VALUES(34);
|
||
|
|
#
|
||
|
|
# SELECT t1.textid AS a, i.intid AS b, t2.textid AS c
|
||
|
|
# FROM t t1, i, t t2
|
||
|
|
# WHERE t1.textid = i.intid
|
||
|
|
# AND t1.textid = t2.textid;
|
||
|
|
#
|
||
|
|
# The correct result should be two rows, one with 12|12|12 and the other
|
||
|
|
# with 34|34|34. With this bug, no rows are returned. Bisecting shows that
|
||
|
|
# this bug was introduced with check-in [dd4d67a67454] on 2009-04-23.
