[teiid-issues] [JBoss JIRA] (TEIID-2094) Projecting node issue

Projecting node issue --------------------- Key: TEIID-2094 URL: https://issues.jboss.org/browse/TEIID-2094 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 6.0.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 8.1 If a non-pushed source node (inline view) is located over a projecting node (windowfunctionproject, join, group, or a select node) the resulting construction of the projection/projection indexes will be incorrect or fail - as the input elements will not match the output elements that have been set to the views elements. For example with the exception: java.lang.AssertionError: ASSERTION FAILED: expected reference to be not null at org.teiid.core.util.Assertion.failed(Assertion.java:73) at org.teiid.core.util.Assertion.isNotNull(Assertion.java:100) at org.teiid.core.util.Assertion.isNotNull(Assertion.java:92) at org.teiid.query.processor.relational.RelationalNode.getProjectionIndexes(RelationalNode.java:371) at org.teiid.query.processor.relational.SelectNode.initialize(SelectNode.java:93) Note that not all nodes should be the first child under a source. For example, join/group should not appear there (typically it will be one of project/windowfunctionproject/limit/sort/unionall/select). Other child nodes besides windowfunctionproject/select could have issues, since we are not specifically coding to use a different set of output vs. original elements such as with ProjectNode that holds elements and selectSymbols respectively.
