What are the parameters of the RPAD function in Oracle?
The RPAD function in an Oracle database is used to pad a string with a specified character on the right side, in order to reach a specified length. The parameters for the RPAD function are as follows:
- string: the string to be filled. This parameter is required.
- The length parameter specifies the final length of the string that will be returned. If the original string is already at or exceeds this length, no padding will be done.
- fill_string: the character or substring used for filling. If this parameter is not provided, spaces will be used for filling.
In summary, the RPAD function has three parameters.
- The string to be filled in
- the final length of the returned string
- Characters or substrings used for padding (default is a space)
