The rownum is calculated based on the id of each returned row. SELECT col1 FROM (SELECT col1, ROWNUM r FROM (SELECT col1 FROM table ORDER BY col1)) WHERE r BETWEEN In fact, if you really want to get pagination AND order in a single query on oracle, you have to use the following (this is an example, there are many variants, but it is on of the most simple) : SELECT col1 FROM table WHERE rownum BETWEEN 10 AND 20 Sorry to contradict some here but, on oracle, the simple I've worked with many different database platforms and I think that MySQL and PostgreSQL have the cleanest way to do SQL pagination with LIMIT and OFFSET It is nice to be able to use the same syntax for SQL pagination on both MySQL and PostgreSQL. Well it turns out that it is supported now. I have known that PostgreSQL supports the OFFSET keyword for quite some time, and for some reason I always thought it was not supported by MySQL. Suppose you want page 3 of your SQL result, in that case you want LIMIT 10 OFFSET 20, here is some psudo code to calculate the page offset: When you only allow the page number variable, you can keep control of how many items to show on each page. The page number approach is probably a bit more secure as then someone can't make a page that returns all the rows in your table by manipulating the input variables. There are two different ways I have coded pagination in SQL, either I pass a limit and offset directly as variables, or I provide the page number as a variable. As you would imagine doing this on the database yields much better performance. Often the approach used is to SELECT all the records, and then filter through them on the application server tier, rather than directly on the database. This makes it easy to code multi page results or pagination with SQL. With the OFFSET keyword its just as easy, the following query will give the results for page two: SQL Pagination (return rows 11 through 20) Now suppose you wanted to show the second page, results 11-20. However the LIMIT clause always goes at the end of the query on MySQL, and PostgreSQL. This is similar to the TOP clause on Microsoft SQL Server. So if you have 1000 rows in a table, but only want to return the first 10, you would do something like this: SQL To Return First 10 Rows The LIMIT clause is used to limit the number of results returned in a SQL statement. Both MySQL and PostgreSQL support a really cool feature called OFFSET that is usually used with a LIMIT clause.
