-------------------------------------

             Summary: Rewrite of case with true condition is not correct
                 Key: TEIID-2500
                 URL: https://issues.jboss.org/browse/TEIID-2500
             Project: Teiid
          Issue Type: Feature Request
          Components: Query Engine
    Affects Versions: 6.0.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 8.4

If a secondary searched case condition is always true, then the case will be inappropriately rewritten as just the then expression:

case when ... when true then x else y end

becomes just

x

However the prior cases should still be considered.
