> 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/%3c20110803152250.294...@gmx.net%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}}
