# Random

{% hint style="info" %}
The **`Random()`** generates a random <mark style="color:green;">number</mark>.

This function is NOT SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).
{% endhint %}

{% hint style="success" %}
Returns a random integral number between 0 or a specified minimum value, and a maximum value.\
Returns <mark style="color:red;">**`Invalid expression`**</mark> if one of the parameter values is not a valid number, ~~or is a negative number, or when a maximum value is 0~~, or when the maximum value is less than the specified minimum value or 0 when only the maximum is specified.

As of version 4.2, the Random function also accepts negative numbers **when both min and max values** are provided - just as long as min < max.
{% endhint %}

{% hint style="warning" %}
This function uses 32-bit Integers, therefore the range of valid parameters is

**-2147483648 and +2147483648**
{% endhint %}
