cherry-pick #19472 to release-4.0
What problem does this PR solve?
Issue Number: close #19423
Problem Summary:
Incorrect of anti-semi-join query caused by incorrect
OtherConditionsof the LogicalJoin plan.What is changed and how it works?
What's Changed:
After #13406,
LogicalProjectionwould not allocate newColumnfor column -> column projection, so if we directly modifyInOperandof aColumn, it may effect the filters in the subquery. Make a copy of this column before modifying this field.How it Works:
The filters in the subquery would stay untouched, so they can correctly be put into
EqualConditions/OtherConditionslater.Related changes
