RTRIM removes from the right end of char all of the characters that appear in set. This function is useful for formatting the output of a query.
If you do not specify set, then it defaults to a single blank. If char is a character literal, then you must enclose it in single quotes. RTRIM works similarly to LTRIM.
Both char and set 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 char.
The following example trims all the right-most occurrences of period, slash, and equal sign from a string:
SELECT RTRIM('BROWNING: ./=./=./=./=./=.=','/=.') "RTRIM example" FROM DUAL;
