[teiid-issues] [JBoss JIRA] (TEIID-2094) Projecting node issue
[
https://issues.jboss.org/browse/TEIID-2094?page=com.atlassian.jira.plugin...
]
Steven Hawkins resolved TEIID-2094.
-----------------------------------
Resolution: Done
Resolved by adding a pass-through SourceNode for non-Project/non-select into situations.
See the TestDependentJoins.testDependentView for a scenario that places a select node
under the source.
Will look at refining to not need a new node type, however the initial fix is the most
localized/appropriate to be back-ported.
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
Priority: Critical
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.
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.
