Subject [jira] [Commented] (CASSANDRA-12051) JSON does not take functions
Date Thu, 07 Jul 2016 03:55:10 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15365564#comment-15365564
] 

Tianshi Wang commented on CASSANDRA-12051:
------------------------------------------

It actually supports function now in JSON format.
For anyone who want to insert a current timestamp by JSON format, here is the query:

{code}
The ts column should be timestamp.
insert into test JSON '{"id":2,"ts":"now"}';
{code}
