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.

A column with the NUMBER datatype can be defined as follows: column_name NUMBER (precision, scale) The precision defines the total number of digits. The scale defines the number of digits to the right of the decimal point. If you specify a negative scale, Oracle Database rounds the actual data to the specified number of places to the left of the decimal point. For example, specifying (7,-2) means Oracle Database rounds to the nearest hundredths .
