Jon Haddad opened a ticket (presumably based off this email) - https://issues.apache.org/jira/browse/CASSANDRA-12718
Will get it corrected shortly.

It's very helpful and thank a lot ! By the way, is there any way to report to the document author and update the document? I think it may be confused for a green hand just like me. [email protected] From: Ben Slater Date: 2016-09-28 12:50 To: user Subject: Re: Re: ask for help about exmples of Data Types the document shows My best guess it that you need to remove the quotes from around the zip values (ie change if to zip: 20500 rather than zip: ‘20500’ ) as zip is defined as an int.

For (2), I think you’re missing a comma between } and ‘work’ so the JSON is invalid. I think reading this JIRA https://issues.apache.org/jira/browse/CASSANDRA-7423 that the change requiring a UDT as part of a collection to be explicitly marked as frozen is relatively recent (3.6) so the doco may be out date there.

I don't know where to report or ask for help, so I'm very sorry if this mail bother you. In the chapter The Cassandra Query Language (CQL)/Data Types (http://cassandra.apache.org/doc/latest/cql/types.html), I'm confused with two examples the document showing below. My enviroment is: CentOS release 6.8 (Final) java version "1.8.0_91" Java(TM) SE Runtime Environment (build 1.8.0_91-b14) Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode) Python 2.7.11 Cassandra version: 3.7 CQL version: [cqlsh 5.0.1 | Cassandra 3.7 | CQL spec 3.4.2 | Native protocol v4] 1、 in http://cassandra.apache.org/doc/latest/cql/types.html, when describing type set, the giving example is: CREATE TABLE images ( name text PRIMARY KEY, owner text, tags set<text> // A set of text values ); INSERT INTO images (name, owner, tags) VALUES ('cat.jpg', 'jsmith', { 'pet', 'cute' }); // Replace the existing set entirely UPDATE images SET tags = { 'kitten', 'cat', 'lol' } WHERE id = 'jsmith'; the update cql statement uses "WHERE id = 'jsmith'" while the table images did not define key "id". I think it's just a slip of the pen. 2、 in http://cassandra.apache.org/doc/latest/cql/types.html, when describing “User-Defined Types”, the giving example is: CREATE TYPE phone ( country_code int, number text, ) CREATE TYPE address ( street text, city text, zip int, phones map<text, phone> ) CREATE TABLE user ( name text PRIMARY KEY, addresses map<text, frozen<address>> ) and when I try to create type address, one error occur: cqlsh:counterks> CREATE TYPE address ( ... street text, ... city text, ... zip int, ... phones map<text, phone> ... ); InvalidRequest: code=2200 [Invalid query] message="Non-frozen UDTs are not allowed inside collections: map<text, phone>" I change the create statement, like: CREATE TYPE address ( street text, city text, zip int, phones map<text, frozen<phone>> ); it works, and the create table user statement works well. Unfortunately, when running the insert statement below, error occur: INSERT INTO user (name, addresses) VALUES ('z3 Pr3z1den7', { 'home' : { street: '1600 Pennsylvania Ave NW', city: 'Washington', zip: '20500', phones: { 'cell' : { country_code: 1, number: '202 456-1111' }, 'landline' : { country_code: 1, number: '...' } } } 'work' : { street: '1600 Pennsylvania Ave NW', city: 'Washington', zip: '20500', phones: { 'fax' : { country_code: 1, number: '...' } } } }) error: SyntaxException: <ErrorMessage code=2000 [Syntax error in CQL query] message="line 10:14 mismatched input 'work' expecting '}' (...: '...' } } } ['wor]k' :...)"> Is the any suggestion about the problem 2?
