Add additional detection for conflicting criteria to help optimize query plan ----------------------------------------------------------------------------- Key: TEIID-1389 URL: https://issues.jboss.org/browse/TEIID-1389 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 6.0.0 Reporter: Marc Shirley Assignee: Steven Hawkins Fix For: 7.3 Add additional detection for conflicting criteria such as "(column1=1 OR column1=2) AND column1=3". The attempted use case was a case of a UNION that was using the column as a measure of selecting a specific datasource, with each query joined by the UNION having a specific set of column1 values (such as "column1=1 OR column1=2"). In the case of the end user application submitting criteria such as "column1=3", the query planner should prune any branches of the UNION with a conflicting set of values for column1. It would also be helpful if other operators such as <, >, <>, IN, etc. could be accounted for.
