{ column_name data_type [ COMMENT comment ]

<div class="section" id="description">
<h2>Description</h2>
<p>Create a new, empty table with the specified columns.
Use <a class="reference internal" href="create-table-as.html"><span class="doc">CREATE TABLE AS</span></a> to create a table with data.</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 table 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 table. To list all available table
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">table_properties</span>
</pre></div>
</div>
<p>The <code class="docutils literal"><span class="pre">LIKE</span></code> clause can be used to include all the column definitions from
an existing table in the new table. Multiple <code class="docutils literal"><span class="pre">LIKE</span></code> clauses may be
specified, which allows copying the columns from multiple tables.</p>
<p>If <code class="docutils literal"><span class="pre">INCLUDING</span> <span class="pre">PROPERTIES</span></code> is specified, all of the table properties are
copied to the new table. If the <code class="docutils literal"><span class="pre">WITH</span></code> clause specifies the same property
name as one of the copied properties, the value from the <code class="docutils literal"><span class="pre">WITH</span></code> clause
will be used. The default behavior is <code class="docutils literal"><span class="pre">EXCLUDING</span> <span class="pre">PROPERTIES</span></code>. The
<code class="docutils literal"><span class="pre">INCLUDING</span> <span class="pre">PROPERTIES</span></code> option maybe specified for at most one table.</p>
</div>
<div class="section" id="examples">
<h2>Examples</h2>
<p>Create a new table <code class="docutils literal"><span class="pre">orders</span></code>:</p>
