---------------------------------
Sorry, since I am a front-end engineer, I am not able to handle the errors
mentioned above, so I ask you to assign an engineer to deal with this problem.
I will turn off the corresponding pull request, but this problem exists.
Thank you

> 'from_table_clause' when parsing 'from_join_clause'.
>
> example:
> Parse sql {{SELECT `k1, v1, k2, v2 FROM a JOIN b ON k1 = k2;`.}}
> Now grammar will parse `{{JOIN`}} as a `{{from_alias_clause`}}, but it should
> be
> a `{{from_join_clause`}};
