<p>This statement detaches an additional database connection previously 
attached using the <a href="lang_attach.html">ATTACH</a> statement.  
When not in <a href="sharedcache.html">shared cache mode</a>, 
it is possible to have the same database file attached multiple times using 
different names, and detaching one connection to a file will leave the 
others intact.</p>

<p>
In <a href="sharedcache.html">shared cache mode</a>, attempting to attach the same database file more
than once results in an error.
</p>
