Hi,
Use the Offset and Limit in the SQL query.
http://developer.postgresql.org/docs/postgres/queries-limit.html
For example:
SELECT select_list
FROM table_expression
WHERE condition
Let's supose that this query returnes normaly 30000 elements.
SELECT select_list
FROM table_expression
WHERE condition
LIMIT 50
OFFSET 10000
This query will return 50 elements starting with the 10000 elements... so
the elemenst from 10000 to 10050.
Hope that helps.
Best regards,
Andy.
