Row numbering functions uniquely number the rows in a partition. Two row numbering functions are supported: NUMBER and ROW_NUMBER. It is recommended that you use the ROW_NUMBER function because it is an ANSI standard-compliant function that provides much of the same functionality as the NUMBER(*) function. While both functions perform similar tasks, there are several limitations to the NUMBER function that do not exist for the ROW_NUMBER function.
