> Project: Calcite
> Issue Type: Bug
> Affects Versions: 0.9.1-incubating
> Reporter: hongbin ma
> Assignee: Julian Hyde
>
> 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
