<a href="../c3ref/intro.html"><h2>SQLite C Interface</h2></a>
<h2>Reset A Prepared Statement Object</h2>
</div>
<blockquote><pre>
int sqlite3_reset(sqlite3_stmt *pStmt);
</pre></blockquote>
<p>
The sqlite3_reset() function is called to reset a <a href="../c3ref/stmt.html">prepared statement</a>
object back to its initial state, ready to be re-executed.
Any SQL statement variables that had values bound to them using
the <a href="../c3ref/bind_blob.html">sqlite3_bind_*() API</a> retain their values.
Use <a href="../c3ref/clear_bindings.html">sqlite3_clear_bindings()</a> to reset the bindings.</p>
<p>The <a href="../c3ref/reset.html">sqlite3_reset(S)</a> interface resets the <a href="../c3ref/stmt.html">prepared statement</a> S
back to the beginning of its program.</p>
<p>The return code from <a href="../c3ref/reset.html">sqlite3_reset(S)</a> indicates whether or not
the previous evaluation of prepared statement S completed successfully.
If <a href="../c3ref/step.html">sqlite3_step(S)</a> has never before been called on S or if
<a href="../c3ref/step.html">sqlite3_step(S)</a> has not been called since the previous call
to <a href="../c3ref/reset.html">sqlite3_reset(S)</a>, then <a href="../c3ref/reset.html">sqlite3_reset(S)</a> will return
<a href="../rescode.html#ok">SQLITE_OK</a>.</p>
<p>If the most recent call to <a href="../c3ref/step.html">sqlite3_step(S)</a> for the
<a href="../c3ref/stmt.html">prepared statement</a> S indicated an error, then
<a href="../c3ref/reset.html">sqlite3_reset(S)</a> returns an appropriate <a href="../rescode.html">error code</a>.
The <a href="../c3ref/reset.html">sqlite3_reset(S)</a> interface might also return an <a href="../rescode.html">error code</a>
if there were no prior errors but the process of resetting
the prepared statement caused a new error. For example, if an
<a href="../lang_insert.html">INSERT</a> statement with a <a href="../lang_returning.html">RETURNING</a> clause is only stepped one time,
that one call to <a href="../c3ref/step.html">sqlite3_step(S)</a> might return SQLITE_ROW but
the overall statement might still fail and the <a href="../c3ref/reset.html">sqlite3_reset(S)</a> call
might return SQLITE_BUSY if locking constraints prevent the
database change from committing. Therefore, it is important that
applications check the return code from <a href="../c3ref/reset.html">sqlite3_reset(S)</a> even if
no prior call to <a href="../c3ref/step.html">sqlite3_step(S)</a> indicated a problem.</p>
<p>The <a href="../c3ref/reset.html">sqlite3_reset(S)</a> interface does not change the values
of any <a href="../c3ref/bind_blob.html">bindings</a> on the <a href="../c3ref/stmt.html">prepared statement</a> S.

<a href="../c3ref/objlist.html">Objects</a>,
