The underlying library doesn't support + prepared statements, so the driver emulates them, and the + untrusted input is merged into the SQL statement.</p> + <p>It can be made safe by <em>untainting</em> all inputs: + a process inspired by Perl's taint checking.

The regexp follows immediately + after the % in the prepared statement, and is enclosed in + curly brackets {}. For example, if your application expects + alphanumeric input, you can use:</p> + <div class="example"><p><code> + <code>"SELECT foo FROM bar WHERE input = %s"</code> + </code></p></div> + <p>with other drivers, and suffer nothing worse than a failed query. + But with FreeTDS you'd need:</p> + <div class="example"><p><code> + <code>"SELECT foo FROM bar WHERE input = %{([A-Za-z0-9]+)}s"</code> + </code></p></div> + <p>Now anything that doesn't match the regexp's $1 match is + discarded, so the statement is safe.</p> + <p>An alternative to this may be the third-party ODBC driver, + which offers the security of genuine prepared statements.</p> +</div> +<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> +<div class="directive-section"><h2><a name="DBDExptime" id="DBDExptime">DBDExptime</a> <a name="dbdexptime" id="dbdexptime">Directive</a></h2> +<table class="directive"> +<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Keepalive time for idle connections</td></tr> +<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>DBDExptime <var>time-in-seconds</var></code></td></tr> +<tr><th><a href="directive-dict.html#Default">Default:</a></th><td><code>DBDExptime 300</code></td></tr> +<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> +<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr> +<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_dbd</td></tr> +</table> + <p>Set the time to keep idle connections alive when the number + of connections specified in DBDKeep has been exceeded (threaded + platforms only).</p> + +</div> +<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div> +<div class="directive-section"><h2><a name="DBDInitSQL" id="DBDInitSQL">DBDInitSQL</a> <a name="dbdinitsql" id="dbdinitsql">Directive</a></h2> +<table class="directive"> +<tr><th><a href="directive-dict.html#Description">Description:</a></th><td>Execute an SQL statement after connecting to a database</td></tr> +<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>DBDInitSQL <var>"SQL statement"</var></code></td></tr> +<tr><th><a href="directive-dict.html#Context">Context:</a></th><td>server config, virtual host</td></tr> +<tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr> +<tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_dbd</td></tr> +</table> + <p>Modules, that wish it, can have one or more SQL statements + executed when a connection to a database is created.
