My Table:
ID NAME
1 SIVA
2 RAJA
3 PYTHON
4 SQL
5 ODI
I need to lead by 3 rows.
My SQL Query:
SELECT LEAD(NAME,3) OVER (ORDER by NAME) as NAME FROM TEST_TABLE where NAME='SIVA'
EXPECTED OUTPUT:
--------
| NAME |
--------
| SQL |
--------
Example:
If I pass value as SIVA, then I need to get SQL as output.
Similarly if I pass value as Raja, then I need to get ODI as output
Is there any query to get the expected output?
This might be one option: it uses row_number analytic function which calculates row numbers so that you wouldn't have to rely on ID values. What if they are acquired by a sequence? It is not gapless. Basically - it is used for safety.
SQL> WITH test (id, name)
2 AS (SELECT 1, 'siva' FROM DUAL
3 UNION ALL
4 SELECT 2, 'raja' FROM DUAL
5 UNION ALL
6 SELECT 3, 'python' FROM DUAL
7 UNION ALL
8 SELECT 4, 'sql' FROM DUAL
9 UNION ALL
10 SELECT 5, 'odi' FROM DUAL),
11 temp AS (SELECT id, name, ROW_NUMBER () OVER (ORDER BY id) rn FROM test)
12 SELECT b.name
13 FROM temp a JOIN temp b ON b.rn = a.rn + 3
14 WHERE a.name = '&name';
Enter value for name: siva
