Review Comment:
why not set sortClause and limitClause to optional?
so you don't have to check limit is present in visitLimitClause
```antlr4
queryOrganization
: sortClause? limitClause?
;
sortItem
: expression ordering = (ASC | DESC)
;
limitClause
: (LIMIT limit=INTEGER_VALUE)
| (LIMIT limit=INTEGER_VALUE OFFSET offset=INTEGER_VALUE)
| (LIMIT offset=INTEGER_VALUE COMMA limit=INTEGER_VALUE)
;
```
