<a href="intro.html"><h2>Session Module C Interface</h2></a><h2>Test if a changeset has recorded any changes.</h2><blockquote><pre>int sqlite3session_isempty(sqlite3_session *pSession);
</pre></blockquote><p>
Return non-zero if no changes to attached tables have been recorded by 
the session object passed as the first argument. Otherwise, if one or 
more changes have been recorded, return zero.</p>

<p>Even if this function returns zero, it is possible that calling
<a href="../session/sqlite3session_changeset.html">sqlite3session_changeset()</a> on the session handle may still return a
changeset that contains no changes. This can happen when a row in 
an attached table is modified and then later on the original values 
are restored. However, if this function returns non-zero, then it is
guaranteed that a call to sqlite3session_changeset() will return a 
changeset containing zero changes.
