<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Total Number Of Rows Modified</h2><blockquote><pre>int sqlite3_total_changes(sqlite3*);
</pre></blockquote><p>
This function returns the number of row changes caused by <a href="../lang_insert.html">INSERT</a>,
<a href="../lang_update.html">UPDATE</a> or <a href="../lang_delete.html">DELETE</a> statements since the <a href="../c3ref/sqlite3.html">database connection</a> was opened.
The count returned by sqlite3_total_changes() includes all changes
from all <a href="../lang_createtrigger.html">trigger</a> contexts and changes made by
<a href="../foreignkeys.html#fk_actions">foreign key actions</a>. However,
the count does not include changes used to implement <a href="../lang_replace.html">REPLACE</a> constraints,
do rollbacks or ABORT processing, or <a href="../lang_droptable.html">DROP TABLE</a> processing.  The
count does not include rows of views that fire an <a href="../lang_createtrigger.html#instead_of_trigger">INSTEAD OF trigger</a>,
though if the INSTEAD OF trigger makes changes of its own, those changes
are counted.
The sqlite3_total_changes() function counts the changes as soon as
the statement that makes them is completed (when the statement handle
is passed to <a href="../c3ref/reset.html">sqlite3_reset()</a> or <a href="../c3ref/finalize.html">sqlite3_finalize()</a>).</p>

<p>See also the <a href="../c3ref/changes.html">sqlite3_changes()</a> interface, the
<a href="../pragma.html#pragma_count_changes">count_changes pragma</a>, and the <a href="../lang_corefunc.html#total_changes">total_changes() SQL function</a>.</p>

<p>If a separate thread makes changes on the same database connection
while <a href="../c3ref/total_changes.html">sqlite3_total_changes()</a> is running then the value
returned is unpredictable and not meaningful.

  <a href="objlist.html">Objects</a>,
