 			<subsection name="Database table">

 				<p>Since version 2.3.0, the appender will <strong>not</strong> create a database table by itself. You
 				have to create a database table yourself. The reason for this is that various databases use various
 				create statements and column types. Some common databases are covered in this chapter.</p>

 				<p>By default the table should contain the following columns: </p>

 				<ul>
 					<li>timestamp DATETIME</li>
 					<li>logger VARCHAR</li>
 					<li>level VARCHAR</li>
 					<li>message VARCHAR</li>
 					<li>thread VARCHAR</li>
 					<li>file VARCHAR</li>
 					<li>line VARCHAR</li>
 				</ul>

 				<p>If you wish to use an alternative table structure, see the next chapter.</p>

 				<p>The following examples show CREATE TABLE statements for some popular databases.</p>

 				<h4>MySQL</h4>

 <pre class="prettyprint">
 CREATE TABLE log4php_log (
     timestamp DATETIME,
     logger VARCHAR(256),
     level VARCHAR(32),
     message VARCHAR(4000),
     thread INTEGER,
     file VARCHAR(255),
     line VARCHAR(10)
 );
 </pre>

 				<h4>SQLite</h4>

 				<p>SQLite does not have a datetime type, so varchar is used instead.</p>

 <pre class="prettyprint">
 CREATE TABLE log4php_log (
     timestamp VARCHAR(50),
     logger VARCHAR(256),
     level VARCHAR(32),
     message VARCHAR(4000),
     thread INTEGER,
     file VARCHAR(255),
     line VARCHAR(10)
 );
 </pre>

 				<h4>PostgreSQL</h4>

 <pre class="prettyprint">
 CREATE TABLE log4php_log (
     timestamp TIMESTAMP,
     logger VARCHAR(256),
     level VARCHAR(32),
     message VARCHAR(4000),
     thread INTEGER,
     file VARCHAR(255),
     line VARCHAR(10)
 );
 </pre>
 			</subsection>

 			<subsection name="Advanced configuration" id="Advanced_configuration">
 				<p>Parameters <code>insertSql</code> and <code>insertPattern</code> can be used to change how events are
 				inserted into the database. By manipulating them, it is possible to use a custom table structure to
 				suit your needs.</p>

 				<p class="alert alert-warning"><strong>WARNING:</strong> Change these settings only if you are sure you
 				know what you are doing.</p>

 				<p>The default values of these parameters are:</p>

 				<table>
 					<thead>
 						<tr>
 							<th>Parameter</th>
 							<th>Default value</th>
 						</tr>
 					</thead>
 					<tbody>
 						<tr>

 						</tr>
 						<tr>
 							<td>insertPattern</td>
 							<td>%date{Y-m-d H:i:s},%logger,%level,%message,%pid,%file,%line</td>
 						</tr>
 					</tbody>
 				</table>

 				<p>The string <em>__TABLE__</em> in <code>insertSql</code> will be replaced with the table name
 				defined in <code>table</code>. Question marks in <code>insertSql</code> will be replaced by evaluated
 				<code><a href="../layouts/pattern.html">LoggerPatternLayout</a></code> format strings defined in
 				<code>insertPattern</code>. See <code><a href="../layouts/pattern.html">LoggerPatternLayout</a></code>
 				documentation for format string description.</p>

 			</subsection>


 			<subsection name="Examples">

 				<h4>Example 1</h4>

 				<p>The simplest example is connecting to an SQLite database which does not require any
 				authentication.</p>

 				<p>SQLite databases are contained in simple files and don't reuquire a server to run. This example will
 				log to the database contained in <code>/var/log/log.sqlite</code>.</p>

 				<p>First, create a database and a table for logging. In this example, let's create the database at
 				<code>/tmp/log.db</code>.</p>

 <pre><![CDATA[
 $ sqlite3 /tmp/log.db
 SQLite version 3.7.9 2011-11-01 00:52:41
 Enter ".help" for instructions
 Enter SQL statements terminated with a ";"
 sqlite> CREATE TABLE log4php_log (
    ...> timestamp VARCHAR(256),
    ...> logger VARCHAR(256),
    ...> level VARCHAR(32),
    ...> message VARCHAR(4000),
    ...> thread INTEGER,
    ...> file VARCHAR(255),
    ...> line VARCHAR(10)
    ...> );
 ]]></pre>

 				<p>When the database is set up, use the following configuration to set up log4php.</p>

 				<div class="auto-tabs">
 					<ul>
 						<li>XML</li>
 						<li>PHP</li>
 					</ul>

 					<div class="tab-content" >
 						<div class="tab-pane">
 <pre class="prettyprint"><![CDATA[
 <configuration xmlns="http://logging.apache.org/log4php/">
     <appender name="default" class="LoggerAppenderPDO">
         <param name="dsn" value="sqlite:/tmp/log.db" />
     </appender>
     <root>
         <appender_ref ref="default" />
     </root>
 </configuration>
 ]]></pre>
 						</div>
 						<div class="tab-pane">
 <pre class="prettyprint"><![CDATA[
 array(
     'appenders' => array(
         'default' => array(
             'class' => 'LoggerAppenderPDO',
             'params' => array(
                 'dsn' => 'sqlite:/tmp/log.db',
             ),
         ),
     ),
     'rootLogger' => array(
         'appenders' => array('default'),
     ),
 );
 ]]></pre>
 						</div>
 					</div>
 				</div>

 				<p>Now the database is ready to accept some logging data.</p>

 <pre class="prettyprint linenums"><![CDATA[
 require 'log4php/Logger.php';
 Logger::configure('config.xml');

 $log = Logger::getLogger('foo');
 $log->info("foo");
 $log->info("bar");
 $log->info("baz");
 ]]></pre>

 				<p>And you can .</p>

 <pre><![CDATA[
 $ sqlite3 /tmp/log.db
 SQLite version 3.7.9 2011-11-01 00:52:41
 Enter ".help" for instructions
 Enter SQL statements terminated with a ";"
 sqlite> select * from log4php_log;
 2012-08-18 17:14:11|foo|INFO|foo|23531|/home/ihabunek/apache/sqlite.php|5
 2012-08-18 17:14:11|foo|INFO|bar|23531|/home/ihabunek/apache/sqlite.php|6
 2012-08-18 17:14:11|foo|INFO|baz|23531|/home/ihabunek/apache/sqlite.php|7
 ]]></pre>

 				<h4>Example 2</h4>

 				<p>A slightly more complex example is connecting to a MySQL database which requires user credentials
 				to be provided. Additionally, a user-specified table name is used.</p>

 				<p>First, a log table has to be created. For this example a database named <code>logdb</code> will be
 				created, and within it a table named <code>log</code>.</p>

 <pre><![CDATA[
 $ mysql -u root -p
 Enter password: *******
 Welcome to the MySQL monitor.  Commands end with ; or \g.
 Your MySQL connection id is 47
 Server version: 5.5.24-0ubuntu0.12.04.1 (Ubuntu)

 mysql> CREATE DATABASE logdb;
 Query OK, 1 row affected (0.00 sec)

 mysql> USE logdb;
 Database changed

 mysql> CREATE TABLE log (
     -> timestamp DATETIME,
     -> logger VARCHAR(256),
     -> level VARCHAR(32),
     -> message VARCHAR(4000),
     -> thread INTEGER,
     -> file VARCHAR(255),
     -> line VARCHAR(10)
     -> );
 Query OK, 0 rows affected (0.01 sec)
 ]]></pre>

 				<p>The following configuration allows log4php to write to the newly created table.</p>

 				<div class="auto-tabs">
 					<ul>
 						<li>XML</li>
 						<li>PHP</li>
 					</ul>

 					<div class="tab-content" >
 						<div class="tab-pane">

         <param name="user" value="root" />
         <param name="password" value="secret" />
         <param name="table" value="log" />
     </appender>
     <root>
         <appender_ref ref="default" />
     </root>
 </configuration>
 ]]></pre>
 						</div>
 						<div class="tab-pane">
 <pre class="prettyprint"><![CDATA[
 array(
     'appenders' => array(
         'default' => array(
             'class' => 'LoggerAppenderPDO',
             'params' => array(
                 'dsn' => 'mysql:host=localhost;dbname=logdb',

                 'table' => 'log',

         ),
     ),

         'appenders' => array('default'),
     ),
 );
 ]]></pre>
 						</div>
 					</div>
 				</div>

 				<p>Now the database is ready to accept some logging data.</p>

 Logger::configure('config.xml');

 $log = Logger::getLogger('main');
 $log->info("foo");

	<h4>Example 2</h4>

	<p>A slightly more complex example is connecting to a MySQL database which requires user credentials
	to be provided. Additionally, a user-specified table name is used.</p>

	<p>First, a log table has to be created. For this example a database named <code>logdb</code> will be
	created, and within it a table named <code>log</code>.</p>

	<pre><![CDATA[
	$ mysql -u root -p
	Enter password: *******
	Welcome to the MySQL monitor. Commands end with ; or \g.
	Your MySQL connection id is 47
	Server version: 5.5.24-0ubuntu0.12.04.1 (Ubuntu)

	mysql> CREATE DATABASE logdb;
	Query OK, 1 row affected (0.00 sec)

	mysql> USE logdb;
	Database changed

	mysql> CREATE TABLE log (
	-> timestamp DATETIME,
	-> logger VARCHAR(256),
	-> level VARCHAR(32),
	-> message VARCHAR(4000),
	-> thread INTEGER,
	-> file VARCHAR(255),
	-> line VARCHAR(10)
	-> );
	Query OK, 0 rows affected (0.01 sec)
	]]></pre>

	<p>The following configuration allows log4php to write to the newly created table.</p>

	<div class="auto-tabs">
	<ul>
	<li>XML</li>
	<li>PHP</li>
	</ul>

	<div class="tab-content" >
	<div class="tab-pane">
	<pre class="prettyprint"><![CDATA[
	<configuration xmlns="http://logging.apache.org/log4php/">
	<appender name="default" class="LoggerAppenderPDO">
	<param name="dsn" value="mysql:host=localhost;dbname=logdb" />
	<param name="user" value="root" />
	<param name="password" value="secret" />
	<param name="table" value="log" />
	</appender>
	<root>
	<appender_ref ref="default" />
	</root>
	</configuration>
	]]></pre>
	</div>
	<div class="tab-pane">
	<pre class="prettyprint"><![CDATA[
	array(
	'appenders' => array(
	'default' => array(
	'class' => 'LoggerAppenderPDO',
	'params' => array(
	'dsn' => 'mysql:host=localhost;dbname=logdb',
	'user' => 'root',
	'password' => 'secret',
	'table' => 'log',
	),
	),
	),
	'rootLogger' => array(
	'appenders' => array('default'),
	),
	);
	]]></pre>
	</div>
	</div>
	</div>

	<p>Now the database is ready to accept some logging data.</p>

	<pre class="prettyprint linenums"><![CDATA[
	require 'log4php/Logger.php';
	Logger::configure('config.xml');

	$log = Logger::getLogger('main');
	$log->info("foo");
	$log->info("bar");
	$log->info("baz");
	]]></pre>

	<p>Finally, to see the newly logged data.</p>

	<pre><![CDATA[
