> I'm trying to do a SQL transform using Calcite SQL syntax. I'm doing an int to boolean cast. My sql looks like this:
>  
> {code:java}
> ,CASE WHEN cast(IsService as BOOLEAN) THEN CASE WHEN IsEligible THEN 1 ELSE 0 END ELSE NULL END AS Reported
> {code}
> Where IsService is an indicator int and IsEligible is a boolean.
>  
>  I get the below error when I run the pipeline:
>  
> {code:java}
> Caused by: org.apache.beam.vendor.calcite.v1_20_0.org.apache.calcite.sql.validate.SqlValidatorException: Cast function cannot convert value of type INTEGER to type BOOLEAN
> {code}
> Calcite should be able to cast Int to boolean according to [documentation|https://calcite.apache.org/docs/reference.html#implicit-type-conversion]
