[teiid-issues] [JBoss JIRA] Updated: (TEIID-1374) Nested correlated reference issue with rewritten queries

Nested correlated reference issue with rewritten queries -------------------------------------------------------- Key: TEIID-1374 URL: https://issues.jboss.org/browse/TEIID-1374 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Attachments: TestCorrelatedReferenceCollectorVisitor.java In a query such as "select * from bqt1.smalla where exists (select intnum from bqt1.smalla x where smalla.intnum = x.intnum and exists (select intnum from bqt1.smalla where exists (select intnum from bqt1.smalla x where smalla.intnum = x.intnum)))" we will inappropriately report that the top exists subquery has 2 correlated references since we see the more deeply nested smalla.intnum also. This is generally not a issue, it can introduce errors in places where subqueries are rewritten, such as with subquery optimization or inherently updatable view queries.
