# 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;
