Jacques Nadeau commented on DRILL-3180:
---------------------------------------
I'll post an updated patch shortly. It addresses your error issues. The example
in the middle, however, includes a local filtering join condition. We won't
initially support pushing this down. Did you mean to write:
{code}
select * from
mp.employees.`employees` e
INNER JOIN
mp.employees.`salaries` s
ON e.`EMP_NO` = s.`EMP_NO`
WHERE s.`to_date` > CURRENT_DATE
{code}
It is much more common to express a separate filtering condition rather than
putting the filter condition in the join.

> I have developed the base code for a JDBC storage-plugin for Apache Drill.
> The code is primitive but consitutes a good starting point for further
> coding. Today it provides primitive support for SELECT against RDBMS with
> JDBC.
> The goal is to provide complete SELECT support against RDBMS with push down
> capabilities.
> Currently the code is using standard JDBC classes.
