Steven Hawkins created TEIID-3253: ------------------------------------- Summary: Expand allowed order by expressions Key: TEIID-3253 URL: https://issues.jboss.org/browse/TEIID-3253 Project: Teiid Issue Type: Enhancement Reporter: Steven Hawkins with a non-simple query we won't allow derived expressions in the order by such as: select max(x), y from t group by y order by case when y is null then 0 else y end We treat this ordering as unrelated - however it is expressed in terms of expressions from the select clause. Mondrian will generate queries of this form, which requires a workaround of modifying the dialect to use ansi null ordering. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
