---------------------------------------
Summary: getValidatedNodeTypeIfKnown should never throw
Key: CALCITE-6327
URL: https://issues.apache.org/jira/browse/CALCITE-6327
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.36.0
Reporter: Claude Brisson
During validation, when a SqlNode has been rewritten (for instance when a
COALESCE call has been rewritten as a CASE call) but does not yet have a
RelDataType, the method SqlValidatorImpl.getValidatedNodeTypeIfKnown() throws
an exception because it relies on
SqlValidatorImpl.getValidatedNodeType(originalExpr), not on
SqlValidatorImpl.getValidatedNodeTypeIfKnown(originalExpr).
