<a href="intro.html"><h2>Session Module C Interface</h2></a><h2>Obtain Conflicting Row Values From A Changeset Iterator</h2><blockquote><pre>int sqlite3changeset_conflict(
sqlite3_changeset_iter *pIter, /* Changeset iterator */
int iVal, /* Column number */
sqlite3_value **ppValue /* OUT: Value from conflicting row */
);
</pre></blockquote><p>
This function should only be used with iterator objects passed to a
conflict-handler callback by <a href="../session/sqlite3changeset_apply.html">sqlite3changeset_apply()</a> with either
<a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_DATA</a> or <a href="../session/c_changeset_conflict.html">SQLITE_CHANGESET_CONFLICT</a>. If this function
is called on any other iterator, <a href="../rescode.html#misuse">SQLITE_MISUSE</a> is returned and *ppValue
is set to NULL.</p>
<p>Argument iVal must be greater than or equal to 0, and less than the number
of columns in the table affected by the current change. Otherwise,
<a href="../rescode.html#range">SQLITE_RANGE</a> is returned and *ppValue is set to NULL.</p>
<p>If successful, this function sets *ppValue to point to a protected
sqlite3_value object containing the iVal'th value from the
"conflicting row" associated with the current conflict-handler callback
and returns SQLITE_OK.</p>
<p>If some other error occurs (e.g. an OOM condition), an SQLite error code
is returned and *ppValue is set to NULL.
