Sergey Soldatov resolved PHOENIX-2907.
--------------------------------------
Resolution: Won't Fix
> UDFs in where clause not work
> -----------------------------
>
> Key: PHOENIX-2907
> URL: https://issues.apache.org/jira/browse/PHOENIX-2907
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.7.0
> Environment: phoenix-4.7.0
> HBase-0.98
> Reporter: wangweiyi
> Assignee: Sergey Soldatov
>
> it's ok to use my UDF after select, like this:
> select myudf("col") from MY_TABLE limit 1;
> then will get:
> MYUDF(cf."col")
> -----------------------
> 2
> then I try to use myudf after where clause, like this:
> select * from MY_TABLE where myudf("col")='2';
> however, this time I get nothing.
> I know the reason is that the "col" column is null, if the "col" column is
> not null then everything works fine. My question is how can I handle the null
> value in my UDF then I can use it in where clause correctly?
