Maciej Sokol commented on CASSANDRA-15458:
------------------------------------------
I've continued searching and found where the issue is, it's in
pylib/cqlshlib/formatting.py.
When map is formatted quote=True is sent to the format function and when text
is formatted quote=False is sent. I.e changing quote=False in the
format_value_map will produce the same results as for text.
{code:java}
SELECT * FROM test.t1;
id | data
----+----------
1 | I'm newb
SELECT * FROM test.t2;
id | data
----+---------------
1 | {1: I'm newb} {code}
So the question arises here, do we want to quote or not quote? I guess we want
to have the same behavior for text as well as text in map.

> h3. Overview
> For {{text}} attributes, CQL allows escaping single quote [using additional
> single
> quote|http://mail-archives.apache.org/mod_mbox/cassandra-user/201108.mbox/%[email protected]%3E].
> But applying the same syntax for a {{map<int,text>}} attribute does not
> work. Inconsistent behavior was observed between {{text}} datatype and
> {{map<int,text>}} datatype.
> h3. CQL semantic proposal
> Cassandra (CQL) should apply same escaping semantics on {{text}} and
> text-within-map {{map<int,text>}} datatypes.
> h3. Reproducing the bug:
> CREATE query:
> {code:java}
> CREATE TABLE university.test (id int, data map<int, text>, PRIMARY KEY
> (id));{code}
> INSERT query:
> {code:java}
> insert into university.test (id, data) values(1, {1:'I''m newb'});{code}
> On running the aforementioned INSERT query, Cassandra inserts and returns
> {{\{1: 'I''m newb'}}} while the expected result is {{\{1: 'I'm newb'}}}
> h3. Technical details
> OS: CentOS 7
> Kernel: Linux 3.10.0-1062.9.1.el7.x86_64
> Cassandra version: 3.11.5
> Screenshot: [Output after SELECT query|https://i.stack.imgur.com/PLAan.png]

> +Additional information for newcomers:+
> The issue seems to come from the ANTLR Lexer logic for {{STRING_LITERAL}}. A
> unit test should also be added in {{SelectTest}}
