Grammer failed to recognize single quote inside string literal

Hi,

Grammer failed to recognize single quote inside string literal.

I am getting error message: no viable alternative at input 'Select * from table_name where (Directory_name FileServer='BL006-FS1' and Directory = 'C:\\D'Intrusion'."

What is the change required to STRING_LITERAL ?

STRING_LITERAL
: '\'' ( ~'\'' | '\'\'' )* '\''
;

该 issue 标识了 STRING_LITERAL 规则；首先在语法中定位该规则，并复现所提供的 SQL-like 输入。确认嵌入式引号的预期转义方式，然后验证该输入解析时不会出现所报告的错误。
