    Hi @KurtYoung , thank your for reviewing. I'm not sure about that. Do you mean omitting the "FROM" syntax ?  But it will be hard to validate SQL syntax. Because the query can follow a WHERE clause or JOIN/UNION with other tables.  For example, it's wired and hard to validate the query like this:
    
    ```
    mytable.sql("SELECT * WHERE a > 13 UNION SELECT * FROM TABLE_B")
    ```
    
    I think allowing query on other tables is fine here.  What do you think ?
