Andy Grove updated ARROW-10728:
-------------------------------
    Description: 
(We cannot do this until we have basic SQL JOIN working)

The USING clause allows a common name to be specified as the join column for an equijoin.

  was:
(We cannot do this until we have basic SQL JOIN working)

A *NATURAL JOIN* is a *JOIN* operation that creates an implicit *join* clause for you based on the common columns in the two tables being *joined*. Common columns are columns that have the same name in both tables. A *NATURAL JOIN* can be an INNER *join*, a LEFT OUTER *join*, or a RIGHT OUTER *join*. The default is INNER *join*.
