CQL: Unable to Null Check in "Where" Clause
10,459
CQL doesn't have the concept of NULL (yet- see CASSANDRA-3783). The right thing to do instead depends on your particular situation.

Try to return all rows where a specific field is null or not null.
select * from ADDRESS where addr1 = null;
or
select * from ADDRESS where addr1 = 'NULL';
addr1 can be a boolean or text field.
I've tried
!= null
,is null
,<> null
, andisnull(addr1, 'NULL')
but I get
no viable alternative at input '='
or
no index columns present in by-columns clause with "equals' operator"
Using Cassandra 1.1.1 & Java 1.7_05
