</div>
<div class="refsect1" lang="en">
<a name="id773064"></a><h2>Description</h2>
<p> <code class="command">DROP TRIGGER</code> will remove an existing
trigger definition. To execute this command, the current
user must be the owner of the table for which the trigger is defined.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id773079"></a><h2>Parameters</h2>
<div class="variablelist"><dl>
<dt><span class="term"><em class="replaceable"><code>name</code></em></span></dt>
<dd><p> The name of the trigger to remove.
</p></dd>
<dt><span class="term"><em class="replaceable"><code>table</code></em></span></dt>
<dd><p> The name (optionally schema-qualified) of the table for which
the trigger is defined.
</p></dd>
<dt><span class="term"><code class="literal">CASCADE</code></span></dt>
<dd><p> Automatically drop objects that depend on the trigger.

<dt><span class="term"><code class="literal">RESTRICT</code></span></dt>

<div class="refsect1" lang="en">
<a name="sql-droptrigger-examples"></a><h2>Examples</h2>
<p> Destroy the trigger <code class="literal">if_dist_exists</code> on the table
<code class="literal">films</code>:
</p>
<pre class="programlisting">DROP TRIGGER if_dist_exists ON films;</pre>
<p>
</p>
</div>
<div class="refsect1" lang="en">
<a name="sql-droptrigger-compatibility"></a><h2>Compatibility</h2>
<p> The <code class="command">DROP TRIGGER</code> statement in
<span class="productname">PostgreSQL</span> is incompatible with the SQL
standard. In the SQL standard, trigger names are not local to
tables, so the command is simply <code class="literal">DROP TRIGGER
<em class="replaceable"><code>name</code></em></code>.
