Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
There were a problem since pruning uses the field
for comparison (while evaluate_join_record uses longlong),
resulting in pruning failures when comparing DATE to DATETIME.
Fix was to always comparing DATE vs DATETIME as DATETIME,
by adding ' 00:00:00' to the DATE string.
And adding optimization for comparing with 23:59:59, so that
DATETIME_col > '2001-02-03 23:59:59' ->
TO_DAYS(DATETIME_col) > TO_DAYS('2001-02-03 23:59:59') instead
of '>='.
mysql-test/r/partition_pruning.result:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Updated result-file
mysql-test/t/partition_pruning.test:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Added testcases.
sql-common/my_time.c:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
removed duplicate assignment.
sql/item.cc:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Changed field_is_equal_to_item into field_cmp_to_item, to
better handling DATE vs DATETIME comparision.
sql/item.h:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Updated comment
sql/item_timefunc.cc:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Added optimization (pruning) of DATETIME where time-part is
23:59:59
sql/opt_range.cc:
Bug#46362: Endpoint should be set to false for TO_DAYS(DATE)
Using the new stored_field_cmp_to_item for better pruning.
