> hi, i'm using the latest optiq-csv(which depends on calcite 0.9.1).
> I even tried changing 0.9.1 to 0.9.2 in optiq-csv's pom, but it will fail "mvn clean install"
> here's my problem:
> ==============================================
>  select  (CASE WHEN (GENDER = 'F') THEN 'woman' ELSE GENDER END), min(EMPID) from EMPS group by (CASE WHEN (GENDER = 'F') THEN 'woman' ELSE GENDER END)
> >>> this works
>  select  (CASE WHEN (GENDER IN ('M','F')) THEN 'known' ELSE GENDER END), min(EMPID) from EMPS group by (CASE WHEN (GENDER IN ('M','F')) THEN 'known' ELSE GENDER END)
> >>> this will not work with exception:
> java.lang.AssertionError: Internal error: while converting CASE WHEN `EMPS`.`GENDER` IN ('M', 'F') THEN 'known' ELSE `EMPS`.`GENDER` END
