SOAR对于having语句的rewrite处理聚合函数存在问题

[llzx373]

Please answer these questions before submitting your issue. Thanks!

1. What did you do?

cat having.sql|./soar.darwin-amd64 -rewrite-rules having -report-type rewrite
select * from x where count(1) > 2 group by t
cat having.sql
select * from x group by t having count(1)>2

2. What did you expect to see?

cat having.sql|./soar.darwin-amd64 -rewrite-rules having -report-type rewrite
select * from x group by t having count(1)>2

3. What did you see instead?

select * from x where count(1) > 2 group by t

4. What version of are you using (soar -version)?

修复建议:

在having的rewrite组件,加入对聚合函数的检查,如果发现是聚合函数的条件,不做这个转化
