Review Comment:
The `TokenManager` will close the `InputStream` when continuously getting
next token until the stream is consumed totally, so don't worry about it.

Review Comment:
After checking the codes of `getNextToken`, I found that when the input
stream is over, it won't return `null` but a `EOF` token. So I think use
condition `token.kind != EOF` may be better?

Review Comment:
To get a completed SQL statement is the function of the
`SqlMultiLineParser`. So I think we can make sure that statement here should
be ended with ';'. And now I think all the test data should be ended with ';'.
