The REPEAT SQL Function in MySQL and MariaDB - Repeat string |
|
| | REPEAT | Syntax: | REPEAT(String, Number) | | Return value: | CHAR | | Function type: | String function | |
| | The function returns a string consisting of "Number" of "String".
An empty string is returned, if "Number" is 0.
If the "String" argument contains a numeric value, it is interpreted as a string.
If "Number" is a floating point value, rounding occurs.
The function returns NULL if "Number" or "String" are null. | SQL Examples for the REPEAT function |

select repeat(1234,5);
