+
+<summary>
+ <p>mod_dbd manages SQL database connections using
+ <a href="http://people.apache.org/~niq/dbd.html">apr_dbd</a>.
+ It provides database connections on request to modules
+ requiring SQL database functions, and takes care of
+ managing databases with optimal efficiency and scalability
+ for both threaded and non-threaded MPMs.</p>
+</summary>
+
+<section id="reslist"><title>Connection Pooling</title>
+ <p>This module manages database connections, in a manner
+ optimised for the platform. On non-threaded platforms,
+ it provides a persistent connection in the manner of
+ classic LAMP (Linux, Apache, Mysql, Perl/PHP/Python).
+ On threaded platform, it provides an altogether more
+ scalable and efficient <em>connection pool</em>, as
+ described in <a href="http://www.apachetutor.org/dev/reslist"
+ title="Connection pooling in Apache">this article at ApacheTutor</a>.
+ mod_dbd supersedes the modules presented in that article.</p>
+</section>
+
+<section id="API"><title>Apache DBD API</title>
+ <p>mod_dbd exports three functions for other modules to use.
+ The API is as follows:</p>
+<pre><code>typedef struct {
+ apr_dbd_t *handle;
+ apr_dbd_driver_t *driver;
+ apr_hash_t *prepared;
+} ap_dbd_t;
+
+/* Export functions to access the database */
+
+/* acquire a connection that MUST be explicitly closed.
+ * Returns NULL on error
+ */
+AP_DECLARE(ap_dbd_t*) ap_dbd_open(apr_pool_t*, server_rec*);
+
+/* release a connection acquired with ap_dbd_open */
+AP_DECLARE(void) ap_dbd_close(server_rec*, ap_dbd_t*);
+
+/* acquire a connection that will have the lifetime of a request
+ * and MUST NOT be explicitly closed. Return NULL on error.
+ * This is the preferred function for most applications.
+ */
+AP_DECLARE(ap_dbd_t*) ap_dbd_acquire(request_rec*);
+
+/* Also export them as optional functions for modules that prefer it */
+APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_open, (apr_pool_t*, server_rec*));
+APR_DECLARE_OPTIONAL_FN(void, ap_dbd_close, (server_rec*, ap_dbd_t*));
+APR_DECLARE_OPTIONAL_FN(ap_dbd_t*, ap_dbd_acquire, (request_rec*));
+</code></pre>
+</section>
+
+<section id="prepared"><title>SQL Prepared Statements</title>
+ <p>mod_dbd supports SQL prepared statements on behalf of
+ modules that may wish to use them. Each prepared statement
+ must be assigned a name (label), and they are stored in a hash:
+ the <code>prepared</code> field of an <code>ap_dbd_t</code>.
+ Hash entries are of type <code>apr_dbd_prepared_t</code>
+ and can be used in any of the apr_dbd prepared statement
+ SQL query or select commands.</p>
+ <p>It is up to dbd user modules to use the prepared statements
+ and document what statements can be specified in httpd.conf.</p>

+<syntax>DBDriver <var>name</var></syntax>
+<contextlist><context>server config</context><context>virtual host</context>
+</contextlist>
+
+<usage>
+ <p>Selects an apr_dbd driver by name. The driver must be installed
+ on your system (on most systems, it will be a shared object or dll).
+ For example, <samp>DBDriver mysql</samp> will select the MySQL
+ driver in apr_dbd_mysql.so.</p>

+<syntax>DBDPersist <var>[0|1]</var></syntax>
+<contextlist><context>server config</context><context>virtual host</context>
+</contextlist>
+
+<usage>
+ <p>If set to 0, persistent and pooled connections are disabled.
+ A new database connection is opened when requested by a client,
+ and closed immediately on release. This option is for debugging
+ and low-usage servers.</p>
+ <p>The default is to enable a pool of persistent connections
+ (or a single LAMP-style persistent connection in the case of a
+ non-threaded server), and should almost always be used in operation.</p>
+</usage>

+<syntax>DBDPrepareSQL <var>"SQL statement"</var> <var>label</var></syntax>
+<contextlist><context>server config</context><context>virtual host</context>
+</contextlist>
+
+<usage>
+ <p>For modules such as authentication that use repeatedly use a
+ single SQL statement, optimum performance is achieved by preparing
+ the statement at startup rather than every time it is used.
+ This directive prepares an SQL statement and assigns it a label.</p>
+</usage>
