title: What is the difference between = and == in hive
body: <p>I accidentally used <code>==</code> instead of <code>=</code> in one of my HQL query, but shockingly it didn't throw any error but was working as it should have been working for <code>=</code>. My question here is why do we have <code>==</code> operator in HQL and what is the exact difference between the two.</p>
