The RPAD SQL Function in MySQL and MariaDB - Pad string on the right side |
|
| | RPAD | Syntax: | RPAD(String, Length, String to append) | | Return value: | CHAR | | Function type: | String function | |
| | The RPAD() function returns "String" with "Length" as the result, with the missing characters being filled with "String to append" on the right side.
If "Length" is less than the length of "String", "String" is returned truncated to the "Length". This then corresponds to the function LEFT().
If "String to append" is not specified, the RPAD() function pads with spaces.
Numeric values of "String" or "String to append" are interpreted as character strings.
If "String" or "String to append" is NULL, the RPAD() function returns NULL.
Before MariaDB 10.3.1, the "String to append" parameter was mandatory.
As of MariaDB 10.3.6 with SQL_MODE=Oracle, NULL is returned if the result is empty.
The Oracle mode version of the function can be accessed outside of Oracle mode by using then RPAD_ORACLE() function. | SQL Examples for the RPAD function |
