RTRIM

Syntax

Description of rtrim.gif follows
Description of the illustration rtrim.gif

Purpose

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 quotation marks. 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 if char is a character datatype, NVARCHAR2 if expr1 is a national character datatype, and a LOB if char is a LOB datatype.
