Note: QUERY_ SQL is a query SQL statement.

Or

Select * from (select rownum rn, id from TABLENAME where rownum <= (currentpage + 1) * pagesize) A where A. rn> = (currentpage * pagesize)

2. Infomix Database

Select skip currentpage first pagesize * from TABLENAME
 
3. DB2 database

Select * from (select Field 1, Field 2, Field 3, rownumber () over (column name asc used for order by sorting) as RN from table name) as A1 where A1.RN between (currentpage * pagesize) and (currentpage + 1) * pagesize)
Or
Select * from (select rownumber () over (order by id asc) as rowid from table where rowid <= (currentpage + 1) * pagesize )) where rowid> (currentpage * pagesize)
