set a value to null in cassandra with cql

Solution 1
It might be done with DELETE
CQL command:
DELETE ric FROM instruments WHERE code='code';
Solution 2
You can also use the value null
in your queries. This was added last year to CQL.
update keyspace.table set ric=null where code='code';
You can also use null
in insert
statements, but if you omit the value it's the same as saying null
so there's no point.

How can I set a value of a row to null in cassandra? For example I have a table like this:
CREATE TABLE instruments ( code text, ric text, primary key (code) )
if I want an element to have a particular
ric
:update instruments set ric='test' where code='code';
But what about setting
ric
toNone
?
