Bart Vanhaute commented on HHH-3988:
------------------------------------
Note that the join does not even have to be on the same table. If you have two different
tables with identical column names, and create a query that joins these two tables and
select tthose identical columns, you will see the same problem.
As a workaround, define an alias for at least one of the identical column names in your
query.
For instance:
select log.from_number, log.to_number, entries_from.name fromName, entries_to.name toName
from test_log log
left join test_entries entries_from on log.from_number=entries_from.number
left join test_entries entries_to on log.to_number=entries_to.number
double left join within same column names returns wrong result
