Will Noble created CALCITE-5635: ----------------------------------- Summary: Consult type mappings when coercing types. Key: CALCITE-5635 URL: https://issues.apache.org/jira/browse/CALCITE-5635 Project: Calcite Issue Type: Improvement Components: core Reporter: Will Noble
This is another offshoot of CALCITE-5346. In [{{AbstractTypeCoercion.implicitCast}}|https://github.com/apache/calcite/blob/2dba40e7a0a5651eac5a30d9e0a72f178bd9bff2/core/src/main/java/org/apache/calcite/sql/validate/implicit/AbstractTypeCoercion.java#L713], Calcite may insert {{CAST}} invocations disregarding the root schema type map. This happens during the validation phase, so it's easy enough to read the type map directly in the {{AbstractTypeCoercion}} utility, although it's hard to say if this is an optimal solution. It may make sense to incorporate the type map into the {{RelDataTypeSystem}} which is more widely available in non-validation phases of SQL processing pipelines. -- This message was sent by Atlassian Jira (v8.20.10#820010)
