Example

mysql> Select RAND(1), RAND(1), Rand(1);
+---------------------+---------------------+---------------------+
| RAND(1)             | RAND(1)             | Rand(1)             |
+---------------------+---------------------+---------------------+
| 0.40540353712197724 | 0.40540353712197724 | 0.40540353712197724 |
