Zhen Chen updated CALCITE-6904:
-------------------------------
Summary: IS_NOT_DISTINCT_FROM is converted error in ElementerableJoinRule
(was: Is not distinct from conversion error in ElementerableJoinRule)
> IS_NOT_DISTINCT_FROM is converted error in ElementerableJoinRule
> ----------------------------------------------------------------
>
> Key: CALCITE-6904
> URL: https://issues.apache.org/jira/browse/CALCITE-6904
> Project: Calcite
> Issue Type: Bug
> Reporter: Zhen Chen
> Priority: Major
>
> The convert method of ElementerableJoinRule incorrectly converts the
> condition of `is not distinct from`, which is considered an equivalence
> condition in calcite and carries a `filterNulls` to save whether to perform
> equivalence processing on null. However, when converting to
> ElementerableJoin, the filterNulls are ignored, resulting in
> `is_not_distinct_from ($0, $1)` being converted to `=($0, $1)`.
