Description Juraj Duráni 2015-11-09 13:50:54 UTC 
Oracle translator translates OFFSET function as:
SELECT c_0 FROM (SELECT VIEW_FOR_LIMIT.*, ROWNUM ROWNUM_ FROM (***Query***) VIEW_FOR_LIMIT WHERE ROWNUM <= -2147483604) WHERE ROWNUM_ > 45

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

Example:
Query:
SELECT INTKEY FROM bqt1.smalla ORDER BY INTKEY OFFSET 45 ROWS

Source-specific command:
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

The Teiid still returns no row.
