Gleb Kanterov commented on BEAM-8039:
-------------------------------------
A workaround would be supporting COUNTIF function from ZetaSQL, that might be
easier to implement than more generic rewrites.
> SUM(CASE WHEN xxx THEN 1 ELSE 0)

> Key: BEAM-8039
> URL: https://issues.apache.org/jira/browse/BEAM-8039
> Project: Beam
> Issue Type: Sub-task
> Components: dsl-sql-zetasql
> Reporter: Rui Wang
> Priority: Major
>
> java.lang.RuntimeException: Aggregate function only accepts Column Reference
> or CAST(Column Reference) as its input.
> I was able to rewrite SQL using WITH statement, and it seemed to work, but
> requires us rewriting a lot of queries and makes them pretty much unreadable.
