Oracle - Alternative Quoting Mechanism (''Q'') for String Literals - parsing error

Parsing Oracle statement:
COMMENT ON COLUMN EMP.NAME IS q'{Name}';

CCJSqlParserUtil.parseStatements error:
net.sf.jsqlparser.JSQLParserException: net.sf.jsqlparser.parser.ParseException: Encountered unexpected token: "Q" <S_IDENTIFIER>
at line 1, column 31.

But, it's OK:
select q'{Its good!}' from dual;

Another parsing error:
select q'{It's good!}' from dual;

Greetings!

please check the COMMENT Statement.
It expects a CHAR_LITERAL which does not understand the q Escape sequence.

Your SELECT example is not working either, just accidentally parsed as an ALIAS:

Greetings!

I have fixed it partially via PR #1722 allowing at least common brackets such as q'{..}', q'[..]', q'(..)' and q''..''. A generic solution supporting any character is not (easily?) possible with JavaCC.
