12 # This file implements regression tests for SQLite library. The
13 # focus of this file is testing the LIKE and GLOB operators and
14 # in particular the optimizations that occur to help those operators
15 # run faster and that those optimizations work correctly when there
16 # are both strings and blobs being tested.
18 # Ticket 05f43be8fdda9fbd948d374319b99b054140bc36 shows that the following
19 # SQL was not working correctly:
21 # CREATE TABLE t1(x TEXT UNIQUE COLLATE nocase);
22 # INSERT INTO t1(x) VALUES(x'616263');
23 # SELECT 'query-1', x FROM t1 WHERE x LIKE 'a%';
24 # SELECT 'query-2', x FROM t1 WHERE +x LIKE 'a%';
26 # This script verifies that it works right now.
