Caican Cai commented on CALCITE-6409:
-------------------------------------

I'm not sure if this is a bug. If not should I write a new isComparable method to adapt to spark

> In the SameOperandTypeChecker method, the char type and the boolean type are comparable because of the call to the isComparable method. 
> Comparability of char types and boolean types returns true in the isComparable method. 
> However, char types and Boolean types in Spark are incomparable. Does Calcite have fixed standards here?
