Steven Hawkins commented on TEIID-5875:
---------------------------------------

The simplest scenario in which this can happen is with a mongodb view that suppresses the _id field.  That view is still reported as a collection and so it's easy to sample a row only contains a reference to another ojbect - in which case without an id and other columns a table with no columns is created.

> The mongodb metadata import adds tables before determining what columns are available.  In some circumstances this results in tables with no columns.
