Scenario = To display a search result for all the employees in a org.
[ Normally the query will retrieve 1000 records (say) ]
1) Query to retrieve just the first 10 of the thousand records
2) Then have a link called "Next" and "Previous" in the Web page .
3) When Link is clicked , for instance when the user click "Next" then show records
from 11-20 ..
Qs. Will the following SQL Query be EFFICIENT for such retrievals w.r.t. Performance
Load ?

Hi,
any chance that you let us know what your front end is?
Web? CS-Forms? <fill_in_the_appropriate>?
Come on, some more infos. Typing isn't that hard ;-)

CASE
select * from table gives 1000 records (say)
We want only first ten of these records to be returned to the front end
& then records 11 to 20 & so on ...
How may the above be optimally possible ?
SQL or PL/SQL any for it ?
Thanks
