<h2>Name</h2>

<h2>Synopsis</h2>

</div>
<div class="refsect1" lang="en">
<a name="id740314"></a><h2>Description</h2>
<p> <code class="command">ABORT</code> rolls back the current transaction and causes
all the updates made by the transaction to be discarded.
This command is identical
in behavior to the standard <acronym class="acronym">SQL</acronym> command
<a href="sql-rollback.html">ROLLBACK</a>,
and is present only for historical reasons.
</p>

<div class="variablelist"><dl>
<dt>
<span xmlns="http://www.w3.org/TR/xhtml1/transitional" class="term"><code xmlns="" class="literal">WORK</code></span><br xmlns="http://www.w3.org/TR/xhtml1/transitional"></br><span class="term"><code class="literal">TRANSACTION</code></span>

</dl></div>

<div class="refsect1" lang="en">
<a name="id740372"></a><h2>Notes</h2>
<p> Use <a href="sql-commit.html">COMMIT</a> to
successfully terminate a transaction.
</p>
<p> Issuing <code class="command">ABORT</code> when not inside a transaction does
no harm, but it will provoke a warning message.
</p>
</div>
<div class="refsect1" lang="en">
<a name="id740404"></a><h2>Examples</h2>
<p> To abort all changes:
</p>
<pre class="programlisting">ABORT;</pre>
<p>
</p>
</div>
<div class="refsect1" lang="en">
<a name="id740417"></a><h2>Compatibility</h2>
<p> This command is a <span class="productname">PostgreSQL</span> extension
present for historical reasons. <code class="command">ROLLBACK</code> is the
equivalent standard SQL command.
