Mark Addleman created TEIID-2748:
------------------------------------
Summary: Ensure pushdown of multisource column expressions
Key: TEIID-2748
URL: https://issues.jboss.org/browse/TEIID-2748
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Reporter: Mark Addleman
Assignee: Steven Hawkins
The issue is that the criteria is not making it into the proper
position for the multisource logic to have an effect. It is implicit that multisource
required a translator that supported equality comparison at least. In this case adding
the xpathValue function, because of weaknesses with the detection of a fully evaluatable,
is then inhibiting the proper placement. That last one is easy to fix and I can ensure
that more complex cases are covered as well.
