Oracle / PLSQL: RPAD Function

This article is written about how to use the Oracle/PLSQL RPAD feature with syntax and examples.


The Oracle/PLSQL RPAD function pads the right-side of a string with a unique set of characters (when string1 is now not null).


The syntax for the RPAD function in Oracle/PLSQL is:

RPAD( string1, padded_length [, pad_string] )

Parameters or Arguments

string1 The string to pad characters to (the right-hand side). padded_length The number of characters to return. If the padded_length is smaller than the authentic string, the RPAD characteristic will truncate the string to the dimension of padded_length. pad_string Optional. This is the string that will be padded to the right-hand side of string1. If this parameter is omitted, the RPAD feature will pad spaces to the right-side of string1.


The RPAD function returns a string value.
