your sqcon rule is a Parser rule (because it begins with a lower case
letter).

have you tried making it a Lexer rule? by up-casing (at least) the first
letter.

and note that when you make it into a Lexer rule, the text of the token
will include the leading and trailing quotes, so you may need to
substring them away.

Hope this helps
