Steven Hawkins commented on TEIID-2457:
---------------------------------------

Was this tested against 7.7.x or even 8.3?

> A sample query which produced the error is: SELECT IntKey FROM BQT1.SmallA INTERSECT SELECT IntNum FROM BQT1.SmallB ORDER BY INTKEY
> How to reproduce:  Run the query using a client such as Squirrel multiple times.  The results varies from returning an Assertion to returning actual results.  In my test I ran the query five times and it returned actual results twice and the Assertion 3 times.  The Assertion can be seen below.
