>             Project: Teiid
>          Issue Type: Bug
>    Affects Versions: 8.7.2.6_2
>            Reporter: Juraj Duráni
>            Assignee: Steven Hawkins
>             Fix For: 8.12.2, 8.13

> 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}
