|
# This file implements tests to verify that the enhancement
|
|
# request documented by ticket 99378177930f87bd is working.
|
|
#
|
|
# The enhancement is that if an aggregate query with a GROUP BY clause
|
|
# uses subexpressions in the arguments to aggregate functions that are
|
|
# also columns of an index, then the values are pulled from the index
|
|
# rather than being recomputed. This has the potential to make some
|
|
# indexed queries works as if the index were covering.
