RTRIM
Removes all the trailing characters in char_expression that are present in char_set and returns
the resultant string. The last character in the result is guaranteed not to be in char_set. If you
do not specify a char_set, trailing blanks are removed.
Example This example illustrates the RTRIM function:
Notes • The first argument to the function must be of type CHARACTER.
SECOND
Syntax
RTRIM ( char_expression [ , char_set ] )
SELECT RPAD ( RTRIM (addr, ' '), 30, '.')
FROM customer ;
• The second argument to the function must be of type CHARACTER.
• The result is of type CHARACTER.
• If the argument expression evaluates to NULL, the result is NULL.
• The char_expression, the character set specified by char_set, and the result can contain
multi-byte characters. Character comparisons are case sensitive and are determined by the
collation table in the database.
