@liancheng Thanks for the code review, most of the them are very valueable
for me.
And also I tried your suggestions, but it's not easy to cover both `sql`
and `hivesql` dialect test code. And I think to use a logical node and use each
dialect's own strategy to convert will more reasonable and easy to understand.
Sorry if I'm wrong.
