Alternatives to LIMIT and OFFSET for paging in Oracle [duplicate]

Question

As of oracle 12c, you could use the top N queries.

SELECT fieldA,fieldB 
FROM table 
ORDER BY fieldA 
OFFSET 5 ROWS FETCH NEXT 14 ROWS ONLY;

http://www.oracle-base.com/articles/12c/row-limiting-clause-for-top-n-queries-12cr1.php

Since you're on 10g, you should be able to simplify the ROWNUM approach using analytic functions

SELECT fieldA, 
       fieldB
  FROM (SELECT fieldA,
               fieldB,
               row_number() over (order by fieldA) rnk
          FROM table_name)
 WHERE rnk BETWEEN 5 AND 14;

You will need to use the rownum pseudocolumn to limit results. See here:

Method-1: For database version Oracle12c or higher

SELECT fieldA, fieldB 
FROM table 
ORDER BY fieldA 
OFFSET 5 ROWS FETCH NEXT 14 ROWS ONLY

Method-2: For database version Oracle11g or lower using analytical function RowNumber()

SELECT fieldA, fieldB
FROM (
    SELECT fieldA, fieldB,
        row_number() over (order by fieldA) rowRank
    FROM table_name
)
WHERE rowRank BETWEEN 5 AND 14;

Method-3: For database version Oracle11g or lower using RowNum

SELECT T.* FROM ( 
SELECT T.*, rowNum as rowIndex
FROM (
    SELECT fieldA, fieldB,
    FROM table_name
)T)T
WHERE rowIndex > 0 AND rowIndex <= 20;

In some cases, I have found method-3 is faster than method-2 since order by clause is mandatory in method 2. However, if your database version is 12c or higher you must go for method-1.
