             Summary: Oracle translator - OFFSET function does not work
                 Key: TEIID-3815
                 URL: https://issues.jboss.org/browse/TEIID-3815
             Project: Teiid
          Issue Type: Bug
    Affects Versions: 8.7.2.6_2
            Reporter: Juraj Duráni
            Assignee: Steven Hawkins


Oracle translator translates OFFSET function as:
{code:sql}
SELECT c_0 FROM (SELECT VIEW_FOR_LIMIT.*, ROWNUM ROWNUM_ FROM (***Query***) VIEW_FOR_LIMIT WHERE ROWNUM <= -2147483604) WHERE ROWNUM_ > 45
{code}

This always returns an empty result because of *ROWNUM <= -2147483604*.

Example:
Query:
{code:sql}
SELECT INTKEY FROM bqt1.smalla ORDER BY INTKEY OFFSET 45 ROWS
{code}

Source-specific command:
{code:sql}
SELECT c_0 FROM (SELECT VIEW_FOR_LIMIT.*, ROWNUM ROWNUM_ FROM (SELECT trunc(g_0."INTKEY") AS c_0 FROM "DV"."SMALLA" g_0 ORDER BY c_0) VIEW_FOR_LIMIT WHERE ROWNUM <= -2147483604) WHERE ROWNUM_ > 45
{code}
