+# 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 |
