<h2>Return The Schema Name For A Database Connection</h2>
</div>
<blockquote><pre>
const char *sqlite3_db_name(sqlite3 *db, int N);
</pre></blockquote>
<p>
The sqlite3_db_name(D,N) interface returns a pointer to the schema name
for the N-th database on database connection D, or a NULL pointer of N is
out of range.  An N value of 0 means the main database file.  An N of 1 is
the "temp" schema.  Larger values of N correspond to various ATTACH-ed
databases.</p>

<p>Space to hold the string that is returned by sqlite3_db_name() is managed
by SQLite itself.  The string might be deallocated by any operation that
changes the schema, including <a href="../lang_attach.html">ATTACH</a> or <a href="../lang_detach.html">DETACH</a> or calls to
<a href="../c3ref/serialize.html">sqlite3_serialize()</a> or <a href="../c3ref/deserialize.html">sqlite3_deserialize()</a>, even operations that
occur on a different thread.  Applications that need to
remember the string long-term should make their own copy.  Applications that
are accessing the same database connection simultaneously on multiple
threads should mutex-protect calls to this API and should make their own
private copy of the result prior to releasing the mutex.
