[ https://issues.jboss.org/browse/TEIID-4498?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-4498: --------------------------------------- The initial commit expanded the handling of the select clause to later in planning - for a limited subset of queries, we can use a left outer join plan instead. The next commit expanded handling further to new scalar subquery cases and the initial handling of possible multi-row cases for scalar subqueries. Unfortunately we don't yet handle composite keys. The final commit will further generalize the multi-row case. -- This message was sent by Atlassian Jira (v7.12.1#712002)
