Generate UUID values by default for each row on column of UUID type in H2 Database Engine
<p>In the <a href="http://h2database.com" rel="noreferrer">H2 database</a>, on a table with a column of <a href="http://h2database.com/html/datatypes.html#uuid_type" rel="noreferrer">UUID data type</a>, how do we specify that we want H2 to generate a <a href="http://docs.oracle.com/javase/8/docs/api/java/util/UUID.html" rel="noreferrer">UUID value</a> by default when an <code>INSERT</code> omits that field?</p>

<p>I know how to <a href="http://docs.oracle.com/javase/8/docs/api/java/util/UUID.html#randomUUID--" rel="noreferrer">generate a UUID</a>. 
I have read the Question, <a href="https://stackoverflow.com/q/36494510/642706"><em>How to insert a specific UUID in h2 database?</em></a>.</p>

<p>My question is about how to ask H2 to generate the UUID value on my behalf.</p>
