I'm not sure if a `RAW` type can has precision, either `SqlTypeName.ANY` or `SqlTypeName.OTHER` is fine for me, the precision constraint for type name is mainly used for sanity check when creating type instances in `RelDataTypeFactory`, Flink has it's own logic for creating this type, so this is not a problem. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
