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.
But the SQL server introduces a new function called row_number() . This function assigns a unique row number starting from 1 to number of records. The following is the statement which is the SQL Server 2005 equivalent of the above query set: This statement doesn't use the temp table.n addition to the row_number() function, SQL Server 2005 also introduces the function rank() . This can be used to rank the records based on another column. An example for the usage of rank function is as follows: The above statement gets the rank of each employee based on his/her join date as a new column.
