[jira] [Commented] (BEAM-8039) SUM(CASE WHEN xxx THEN 1 ELSE 0)

    [ https://issues.apache.org/jira/browse/BEAM-8039?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16914005#comment-16914005 ] 

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.

> 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.
