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.
If you specify LEADING, Oracle removes any leading characters equal to trim_character. 1  If you specify TRAILING, Oracle removes any trailing characters equal to trim_character. 2  If you specify BOTH or none of the three, Oracle removes leading and trailing characters equal to trim_character. If you do not specify trim_character, the default value is a blank space. If you specify only trim_source, Oracle removes leading and trailing blank spaces. The function returns a value with datatype VARCHAR2. The maximum length of the value is the length of trim_source. If either trim_source or trim_character is a null value, then the TRIM function returns a null value. Both trim_character and trim_source can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is of VARCHAR2 datatype and is in the same character set as trim_source.
