----------------------------------
Summary: Using jdbc-simple translator produces Assertion error
Key: TEIID-2457
URL: https://issues.jboss.org/browse/TEIID-2457
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 7.7.6
Reporter: Van Halbert
Assignee: Steven Hawkins
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.
