[teiid-issues] [JBoss JIRA] Resolved: (TEIID-756) Oracle Connector is not producing the correct queries when using a LIMIT clause

Oracle Connector is not producing the correct queries when using a LIMIT clause ------------------------------------------------------------------------------- Key: TEIID-756 URL: https://jira.jboss.org/jira/browse/TEIID-756 Project: Teiid Issue Type: Bug Components: JDBC Connector Affects Versions: 6.0.0, 6.1.0, 6.2.0 Reporter: Larry O'Leary Assignee: Steven Hawkins When using a LIMIT clause in a query, the Oracle Connector rewrites it to something that Oracle will understand. The problem is that the rewritten version of the query is not returning the expected results. For example: SELECT INTKEY FROM BQT1.MEDIUMA LIMIT 50, 100 Should return 50 rows starting at row 100 but instead returns 0 rows when executed via the Oracle Connector. Currently the above query is rewritten as: SELECT * FROM (SELECT VIEW_FOR_LIMIT.*, ROWNUM ROWNUM_ FROM (SELECT MediumA.IntKey FROM MediumA) VIEW_FOR_LIMIT WHERE ROWNUM <= 150) WHERE ROWNUM_ > 50 Further more, the rewritten version of the query is also projecting a column named ROWNUM_ which would be invalid based on our query processing.
