<p>
dbsql is a command line tool that provides access to the Berkeley DB SQL interface. To build this tool, run the configure script with the <code class="literal">--enable-sql </code>option when you are building the Berkeley DB SQL interface.
For more information on building this tool, see <a href="../../installation/build_unix.html#build_unix_intro" class="olink">"Building for UNIX/POSIX"</a>.

if the file does not exist.
