------------------------------------
Summary: RelOptUtil.pushDownJoinConditions does not correctly
adjust ASOF joins match conditions
Key: CALCITE-6540
URL: https://issues.apache.org/jira/browse/CALCITE-6540
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.38.0
Reporter: Mihai Budiu
Assignee: Mihai Budiu
ASOF join was introduced recently by CALCITE-6372
The implementation parallels the join implementation. However, the function
RelOptUtil.pushDownJoinConditions may adjust the join condition. When that
happens, the asof matchCondition may need to be adjusted too. This last
adjustment is missing, which can cause the matchCondition to be wrong, because
the offsets of the RexInputRef fields are not appropriately adjusted.
