Default how to select where rownum BETWEEN 50 and 100?

Hi,

I would like to know how to select a certain number of records,
for example, in a web site, we must display a number of records(25) and we must browse them 25 per 25.

how shall I ask Oracle to give me the 25 next records or the 25 previous records?
for example: first time: select A from B where rownum between 1 and 25
             second time where rownum between 25 and 50
and so on...
can you help me?

thanks in advance.

Michael

This is done with the LIMIT and OFFSET keywords. LIMIT is how many rows to return. OFFSET is the first row of your result set.

Keep in mind that a database stores sets of data -- unless you specify how to order your data, there is no guarantee that the same query will return the result set in the same order. It's always a good idea to use SOME sort of explicit ordering (using ORDER BY <column>) when using LIMIT and OFFSET clauses in your query.


Take care,

Nik
