-------------------------------
Description:
tpc-ds query85.sql run fail when enable TABLE_OPTIMIZER_JOIN_REORDER_ENABLED,
and run success when disable TABLE_OPTIMIZER_JOIN_REORDER_ENABLED .
I analyzed the optimized plan and thought it‘s a negative case for join
reorder feature without table statistic.
was:
tpc-ds query85.sql run fail when enable
TABLE_OPTIMIZER_JOIN_REORDER_ENABLED,and run success when disable
TABLE_OPTIMIZER_JOIN_REORDER_ENABLED.
I analyzed the optimized plan and thought it‘s a bad base for join reorder
feature.
