This Oracle tutorial explains how to use the Oracle/PLSQL ROWNUM function with syntax and examples. The Oracle/PLSQL ROWNUM function returns a number that represents the order that a row is selected by Oracle from a table or joined tables. The first row has a ROWNUM of 1, the second has a ROWNUM of 2, and so on.
By nesting a subquery using ROW_NUMBER inside a query that retrieves the ROW_NUMBER values for a specified range, you can find a precise subset of rows from the results of the inner query. This use of the function lets you implement top-N, bottom-N, and inner-N reporting.t assigns a unique number to each row to which it is applied (either each row in the partition or each row returned by the query), in the ordered sequence of rows specified in the order_by_clause, beginning with 1.
