> In the below query there is no type attached to 'donuts.id' but we expect
> implicit cast to work in this case. Data files referenced are also attached
> create view v1 as select cast(id as int) a, cast(price as double) b from
> prices;
> select v1.a from v1 inner join donuts on v1.a = donuts.id;
> Error From Sqlline : UnsupportedOperationException:[ Failure finding function
> that runtime code generation expected. Signature: compare_to(
> INT:OPTIONALVARCHAR:OPTIONAL, ) returns INT:REQUIRED ]
> With slight modification the below query works
> select v1.a from v1 inner join donuts on v1.a = donuts.id + 1 -1;
