Answer Posted / akash
For implementation through Oracle:
Sort ASC/DESC on rowid in a sub-query and take first 5 rows
of this query in main query.
For implementation through informatica:
1. Use Rank Transformation.
2. Use Sorter Transformation.
The above are for first or last 5 records. Middle 5 records
are not included here.
