SyntaxError as being parsed

SyntaxError: Expected "FROM", "GROUP", "LIMIT", "ORDER", "UNION", "WHERE", WHITE_SPACE, or end of input but "A" found;
e.g. mysql is:
SELECT dd, Max(IF(stat_key = 'yys', stat_us, 0)) AS 'yys_users' FROM waf.t_cpkg WHERE stat_ty = 'waf_ty' GROUP BY dd;
could you please take a look, and update to fix the bug?

Reproduce the reported syntax error with the MySQL query in the issue, then trace the SQL parsing entry point used by nquery. Investigate how the query's MySQL syntax is handled; done means the example parses without the reported error and existing behavior remains intact.
