# Ticket #2942.
|
|
#
|
|
# Queries of the form:
|
|
#
|
|
# SELECT group_concat(x) FROM (SELECT * FROM table ORDER BY 1);
|
|
#
|
|
# The ORDER BY would be dropped by the query flattener. This used
|
|
# to not matter because aggregate functions sum(), min(), max(), avg(),
|
|
# and so forth give the same result regardless of the order of inputs.
|
|
# But with the addition of the group_concat() function, suddenly the
|
|
# order does matter.
