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