Seeing as we’re talking COALESCE and NULLs, depending on the version Ankit is running, this could also be the issue in PHOENIX-2994:-

I think this is a problem with the WHERE clause. NULL values are neither equal nor not-equal to any other values. You might need to add "OR API_KEY IS NULL" to the WHERE clause.

Lukáš is correct, but if the CASE WHEN variant of the same didn't work, please file a JIRA (ideally with a unit test that repros the problem).

I want to implement If null in apache phoenix like mysql.
select ifnull(rowkey,myvalue),ifnull(col1,mycolvalue) from table where rowkey='abc';
I tried below query but did not work:-
select case when APP_KEY is null then 'nullvalue' else APP_KEY end from "CheckDump";
The standard SQL function for this is coalesce(col, 'nullvalue').
