> Key: CALCITE-3476
> URL: https://issues.apache.org/jira/browse/CALCITE-3476
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.21.0
> Reporter: Jark Wu
> Priority: Major

> I want to validate a SqlNode expression and find this interface {{SqlValidator.validateParameterizedExpression(SqlNode topNode, Map<String, RelDataType> nameToTypeMap)}}. The SqlNode expression is {{c + 1}}, and the {{namedToTypeMap}} is {{c -> TIMESTAMP(3)}}. However, it throws following exception.
> After some debug, I found that the {{ParameterScope}} accepts {{namedToTypeMap}} but never use it. We can fix this by overriding {{resolveColumn}} and lookup in the map.
> {code:java}
> @Override
> public RelDataType resolveColumn(String name, SqlNode ctx) {
> return nameToTypeMap.get(name);
> }
