Description

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.
