Update table with random numbers
<p>I need to update my table with random numbers, this is my table:</p>

<pre><code>chr pos ref alt id_disease
chr1 123 A   A     NULL
chr2 456 A   T     NULL
</code></pre>

<p>I want to update the disease column with random numbers from 1 to 30000079.</p>

<p>To obtain this:</p>

<pre><code>chr pos ref alt id_disease
chr1 123 A   A     5024
chr2 456 A   T     300045
</code></pre>

<p>Is there some random functions?</p>
