I've just tested the paging on Oracle in the current (0.9.2) snapshot release but it is still not good.
If the limit function has both the offset and n values set the query is still invalid.
Currenty it looks like this:
SELECT ...
FROM table
OFFSET 20 FETCH FIRST 20 ROWS ONLY
However, it should be like this:
SELECT ...
FROM table
OFFSET 20 ROWS FETCH FIRST 20 ROWS ONLY;
So the ROWS keyword is missing before FETCH.
Thank you for the report, I think that {ROW | ROWS} part of OFFSET.. FETCH syntax is optional
