How to Add Offset in a "Select" Query in Oracle 11G

How to add offset in a select query in Oracle 11g?

You can do it easily on 12c by specifying OFFSET.

In 12c,

SELECT val
FROM table
ORDER BY val
OFFSET 4 ROWS FETCH NEXT 4 ROWS ONLY;

To do the same on 11g and prior, you need to use ROWNUM twice, inner query and outer query respectively.

The same query in 11g,

SELECT val
FROM (SELECT val, rownum AS rnum
FROM (SELECT val
FROM table
ORDER BY val)
WHERE rownum <= 8)
WHERE rnum > 4;

Here OFFSET is 4.

Oracle 11g: LIMIT OFFSET on GROUPED data

This is the widely known question and probably a lot of answered duplicates exist, but anyway in your case this query should work:

select * from (

select rownum offset, rs.* from (

SELECT MAX(t.category) as category,
COUNT(t.category) as count
FROM tb_test_1 t
GROUP BY t.category
/* add order by clause here if needed */

) rs

) where rownum <= 10 /* limit */
and offset >= 0 /* offset */

LIMIT / OFFSET in Oracle 11G

Deleted original answer, not viable

I feel this should be doable in a single SQL statement, but so far the combination of the need for a correlated subquery and the need for some sort of analytic function has made everything I tried fail.

Here's a procedural method that I think will do what you want:

DECLARE
CURSOR t IS
SELECT LEAD(contractid,4) OVER (PARTITION BY assetid ORDER BY lasttradedate ASC) lead_contractid
FROM table1
FOR UPDATE;
BEGIN
FOR r IN t LOOP
UPDATE table1 SET nextcontractid = r.lead_contractid
WHERE CURRENT OF t;
END LOOP;
END;

Oracle 11g OFFSET FETCH gives error

That syntax isn't valid until Oracle Database 12c.

You would say instead

select *
from random_table
where rownum < 11
order by random_column_name;

Apply OFFSET and LIMIT in ORACLE for complex Join Queries?

You can use Analytic functions such as ROW_NUMBER() within a subquery for Oracle 11g assuming you need to get the rows ranked between 3rd and 8th in order to capture the OFFSET 3 LIMIT 8 logic within the Oracle DB(indeed those clauses are included for versions 12c+), whenever the result should be grouped by CREATE_DATE and ordered by the ID of the departments :

SELECT q.*
FROM (SELECT DEPT.ID rowobjid,
DEPT.CREATOR createdby,
DEPT.CREATE_DATE createddate,
DEPT.UPDATED_BY updatedby,
DEPT.LAST_UPDATE_DATE updateddate,
DEPT.NAME name,
DEPT.STATUS status,
statusT.DESCR statusdesc,
REL.ROWID_DEPT1 rowidDEPT1,
REL.ROWID_DEPT2 rowidDEPT2,
DEPT2.DEPT_FROM_VAL parentcid,
DEPT2.NAME parentname,
ROW_NUMBER() OVER (PARTITION BY DEPT.CREATE_DATE ORDER BY DEPT.ID) AS rn
FROM TEST.DEPT_TABLE DEPT
LEFT JOIN TEST.STATUS_TABLE statusT
ON DEPT.STATUS = statusT.STATUS
LEFT JOIN TEST.C_REL_DEPT rel
ON DEPT.ID = REL.ROWID_DEPT2
LEFT JOIN TEST.DEPT_TABLE DEPT2
ON REL.ROWID_DEPT1 = DEPT2.ID) q
WHERE rn BETWEEN 3 AND 8;

which returns exactly 6(8-3+1) rows. If you need to include the ties(the equal values for department identities for each creation date), ROW_NUMBER() should be replaced with another window function called DENSE_RANK() as all other parts of the query remains the same. At least 6 records would return in this case.

Alternatives to LIMIT and OFFSET for paging in Oracle

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

Simple Select with where and offset fetch clause not working in oracle

OFFSET 1 ROWS FETCH NEXT 10 ROWS ONLY is available from Oracle 12c.

Instead, you need to perform your query and order the data; then generate a row number for the ordered rows; and finally filter on those row numbers. These steps need to take place in the correct order in nested sub-queries:

SELECT *
FROM (
SELECT t.*,
ROWNUM AS rn
FROM (
SELECT up.NAME AS upozilaName_bn,
up.id AS upozila,
dis.NAME AS districtName_bn,
dis.id AS district,
dv.NAME AS divisionName_bn,
dv.id AS division,
w.COUNTER_TYPE,
w.COUNTER_ID,
w.STATUS
FROM X w
left join Y up ON w.UPOZILA = up.ID
left JOIN Z dis ON w.DISTRICT = dis.id
left join P dv ON w.DIVISION = dv.ID
order by upozilaName_bn asc
) T
)
WHERE rn BETWEEN 2 AND 11;

Limit Clause in Oracle 11g

In older versions of Oracle, you need a subquery:

select c.*
from (select c.*, row_number() over (order by c.points desc) as seqnum
from customers c
) c
where seqnum = 2;

You will see examples that use rownum in the outer query:

select c.*
from (select c.*
from customers c
) c
where rownum = 2;

However, that does not work, because rownum is incremented only when rows are placed in the result set. Window functions are the simplest solution in older versions of Oracle (new versions support fetch/offset).

Oracle 11g fetch values using offset value

You can use this query and do what u want.

  SELECT A.*
FROM (SELECT A.*, ROWNUM ROWNUMBER
FROM Table1 T
WHERE ROWNUM <= TO) T
WHERE ROWNUMBER > FROM;

FROM is from which number and TO is to which number
