> 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
> Assignee: James Duong
> Priority: Major
>
> 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).
