How can I randomly rearrange the elements in an array column in a Databricks SQL dataset?
You can use the `shuffle` function to randomly rearrange the elements in an array column in a Databricks SQL dataset. The syntax is as follows:

`shuffle(expr)`

Here, `expr` is the array expression that you want to randomly permute. The function returns an array of the same type as `expr`, but with the elements in a random order.

Here's an example query that demonstrates how to use the `shuffle` function:

```sql
SELECT shuffle(array(1, 20, 3, 5));
```

This query returns an array with the elements `[3,1,5,20]`, which is a random permutation of the input array `[1, 20, 3, 5]`.

Note that the `shuffle` function is non-deterministic, which means that it may return a different result each time it is called, even with the same input.
