Oracle Connector is not honouring metadata when rewriting ORDER BY clause ------------------------------------------------------------------------- Key: TEIID-755 URL: https://jira.jboss.org/jira/browse/TEIID-755 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 6.1.0, 6.0.0, 6.2.0 Reporter: Larry O'Leary Assignee: Steven Hawkins Priority: Minor Fix For: 6.2.0 When executing a query that contains an ORDER BY clause, the Oracle Connector is rewriting the query using the column name given by the MM query rather than the source name as specified in the source model. What this means is that column name case is not being enforced. For example: MM User Command: SELECT INTKEY FROM BQT1.SMALLA UNION SELECT INTKEY FROM BQT1.SMALLB ORDER BY INTKEY Model represents INTKEY as IntKey for source name. Currently we rewrite as: SELECT SmallA.IntKey FROM SmallA UNION SELECT SmallB.IntKey FROM SmallB ORDER BY INTKEY This should actually be: SELECT SmallA.IntKey FROM SmallA UNION SELECT SmallB.IntKey FROM SmallB ORDER BY IntKey Although this does not trigger a failure with the current implementation, if the column names were qualified is SQL identifiers, the query would fail as Oracle is expecting a column name of "IntKey" and would not know what "INTKEY" was. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
