# 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.
