How to create a JPA query with pagination parameters (setFirstRows and setMaxRows) and obtain a SQL query like this to run on oracle data base: |
SELECT * FROM (SELECT /*+ FIRST_ROWS_10 / a., ROWNUM rnum FROM (...)
Today the SQL query is generated like:
SELECT * FROM (SELECT /*+ FIRST_ROWS / a., ROWNUM rnum FROM (...)
The second way is far slower than the first.
Is there a query hint to make this customization? I'm using eclipselink 2.1.3.
Thanks. Mauro Flores.
