YUAN created CALCITE-5377:
-----------------------------
Summary: RelFieldTrimmer support Sort with dynamic param
Key: CALCITE-5377
URL: https://issues.apache.org/jira/browse/CALCITE-5377
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.32.0
Reporter: YUAN
If Sort rel node used dynamic param, RelFieldTrimmer can not trim fields as
expected.
The behavior makes ProjectableFilterableTable can not get correct projects.
Related code:
{code:java}
//
org.apache.calcite.sql2rel.RelFieldTrimmer#trimFields(org.apache.calcite.rel.core.Sort,
org.apache.calcite.util.ImmutableBitSet,
java.util.Set<org.apache.calcite.rel.type.RelDataTypeField>)
// leave the Sort unchanged in case we have dynamic limits
if (sort.offset instanceof RexDynamicParam
|| sort.fetch instanceof RexDynamicParam) {
return result(sort, inputMapping);
} {code}
I think we can support dynamic param without breaking anything.
