<h2>Determine If A Prepared Statement Has Been Reset</h2>
</div>
<blockquote><pre>
int sqlite3_stmt_busy(sqlite3_stmt*);
</pre></blockquote>
<p>
The sqlite3_stmt_busy(S) interface returns true (non-zero) if the
<a href="../c3ref/stmt.html">prepared statement</a> S has been stepped at least once using
<a href="../c3ref/step.html">sqlite3_step(S)</a> but has neither run to completion (returned
<a href="../rescode.html#done">SQLITE_DONE</a> from <a href="../c3ref/step.html">sqlite3_step(S)</a>) nor
been reset using <a href="../c3ref/reset.html">sqlite3_reset(S)</a>. The sqlite3_stmt_busy(S)
interface returns false if S is a NULL pointer. If S is not a
NULL pointer and is not a pointer to a valid <a href="../c3ref/stmt.html">prepared statement</a>
object, then the behavior is undefined and probably undesirable.</p>
<p>This interface can be used in combination <a href="../c3ref/next_stmt.html">sqlite3_next_stmt()</a>
to locate all prepared statements associated with a database
connection that are in need of being reset. This can be used,
for example, in diagnostic routines to search for prepared
statements that are holding a transaction open.
