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