<span class="function"><strong>ingres_autocommit()</strong></span> is called before opening a
transaction (before the first call to
<span class="function"><a href="function.ingres-query.html" class="function">ingres_query()</a></span> or just after a call to
<span class="function"><a href="function.ingres-rollback.html" class="function">ingres_rollback()</a></span> or
<span class="function"><a href="function.ingres-commit.html" class="function">ingres_commit()</a></span>) to switch the
autocommit mode of the server on or off (when the script begins
the autocommit mode is off).

<p class="para">
When autocommit mode is on, every query is automatically
committed by the server, as if <span class="function"><a href="function.ingres-commit.html" class="function">ingres_commit()</a></span>

To see if autocommit is enabled use,

<p class="para">
By default Ingres will rollback any uncommitted transactions at the end of
a request. Use this function or <span class="function"><a href="function.ingres-commit.html" class="function">ingres_commit()</a></span> to
ensure your data is committed to the database.
