# This file contains suggested magic(5) text for the unix file(1)
# utility for recognizing SQLite3 databases.
#
# When SQLite is used as an application file format, it is desirable to
# have file(1) recognize the database file as being with the specific
# application.  You can set the application_id for a database file
# using:
#
#     PRAGMA application_id = INTEGER;
#
# INTEGER can be any signed 32-bit integer.  That integer is written as
# a 4-byte big-endian integer into offset 68 of the database header. 
#
# The Monotone application used "PRAGMA user_version=1598903374;" to set
# its identifier long before "PRAGMA application_id" became available.
# The user_version is very similar to application_id except that it is
# stored at offset 68 instead of offset 60.  The application_id pragma
# is preferred.  The rule using offset 60 for Monotone is for historical
# compatibility only.

# This file implements regression tests for compound SELECT statements

# drh added on 2013-05-06 15:21:16:
#
# In the code shown below (which is intended to be run from the
# sqlite3.exe command-line tool) the three SELECT statements should all
# generate the same answer. But the third one does not. It is as if the
# COLLATE clause on the ORDER BY somehow got pulled into the EXCEPT
# operator. Note that the ".print" commands are instructions to the
# sqlite3.exe shell program to output delimiter lines so that you can more
# easily tell where the output of one query ends and the next query
# begins. 
# 
#     CREATE TABLE t1(a);
#     INSERT INTO t1 VALUES('abc'),('def');
#     CREATE TABLE t2(a);
#     INSERT INTO t2 VALUES('DEF');
# 
#     SELECT a FROM t1 EXCEPT SELECT a FROM t2 ORDER BY a;
#     .print -----
#     SELECT a FROM (SELECT a FROM t1 EXCEPT SELECT a FROM t2)
#      ORDER BY a COLLATE nocase;
#     .print -----
#     SELECT a FROM t1 EXCEPT SELECT a FROM t2 ORDER BY a COLLATE nocase;
# 
# Bisecting shows that this problem was introduced in SQLite version 3.6.0
