<h2>Description</h2>
<p>Create a new, empty schema. A schema is a container that
holds tables, views and other database objects.</p>
<p>The optional <code class="docutils literal"><span class="pre">IF</span> <span class="pre">NOT</span> <span class="pre">EXISTS</span></code> clause causes the error to be
suppressed if the schema already exists.</p>
<p>The optional <code class="docutils literal"><span class="pre">WITH</span></code> clause can be used to set properties
on the newly created schema. To list all available schema
properties, run the following query:</p>
<div class="highlight-sql"><div class="highlight"><pre><span></span><span class="k">SELECT</span> <span class="o">*</span> <span class="k">FROM</span> <span class="k">system</span><span class="p">.</span><span class="n">metadata</span><span class="p">.</span><span class="n">schema_properties</span>
