# Bug 1264
|
||||
#
|
||||
# Description:
|
||||
#
|
||||
# When using a ucs2 table in MySQL,
|
||||
# either with ucs2_general_ci or ucs2_bin collation,
|
||||
# words are returned in an incorrect order when using ORDER BY
|
||||
# on an _indexed_ CHAR or VARCHAR column. They are sorted with
|
||||
# the longest word *first* instead of last. I.E. The word "aardvark"
|
||||
# is in the results before the word "a".
|
||||
#
|
||||
# If there is no index for the column, the problem does not occur.
|
||||
#
|
||||
# Interestingly, if there is no second column, the words are returned
|
||||
# in the correct order.
|
||||
#
|
||||
# According to EXPLAIN, it looks like when the output includes columns that
|
||||
# are not part of the index sorted on, it does a filesort, which fails.
|
||||
# Using a straight index yields correct results.
|
||||
|
||||
|
||||
#
|
||||
# Two fields, index
