> Current SQL parser's error message for hyphen-connected identifiers without
> surrounding backquotes(e.g. {{hyphen-table}}) is confusing for end users. A
> possible approach to tackle this is to explicitly capture these wrong usages
> in the SQL parser. In this way, the end users can fix these errors more
> quickly.
