>            Reporter: Mike Higgins
>            Assignee: Steven Hawkins

> This query:
> Edit: <I was asked to remove the query text from the top level description>
> The query is between three different databases chained together with joins (see plans). 
> does not create a dependent join on the middle table.  If you change the join to the middle table to inner, it does.  
> Plans and debug plans for both cases are attached.  As a note, an older version of Teiid that we are also using (9.3.4) always creates the dependent join.  11.0.1 and 10.2.3 do not create the dependent join if the table is outer joined.
