-Database Quick Start: Example Code
-##################################
-
-The following page contains example code showing how the database class
-is used. For complete details please read the individual pages
-describing each function.
-
-Initializing the Database Class
-===============================
-
-The following code loads and initializes the database class based on
-your :doc:`configuration <configuration>` settings::
-
-	$this->load->database();
-
-Once loaded the class is ready to be used as described below.
-
-Note: If all your pages require database access you can connect
-automatically. See the :doc:`connecting <connecting>` page for details.
-
-Standard Query With Multiple Results (Object Version)
-=====================================================
-
-::
-
-	$query = $this->db->query('SELECT name, title, email FROM my_table');
-	
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-		echo $row->name;
-		echo $row->email;
-	}
-	
-	echo 'Total Results: ' . $query->num_rows();
-
-The above result() function returns an array of **objects**. Example:
-$row->title
-
-Standard Query With Multiple Results (Array Version)
-====================================================
-
-::
-
-	$query = $this->db->query('SELECT name, title, email FROM my_table');
-	
-	foreach ($query->result_array() as $row)
-	{
-		echo $row['title'];
-		echo $row['name'];
-		echo $row['email'];
-	}
-
-The above result_array() function returns an array of standard array
-indexes. Example: $row['title']
-
-Standard Query With Single Result
-=================================
-
-::
-
-	$query = $this->db->query('SELECT name FROM my_table LIMIT 1'); 
-	$row = $query->row();
-	echo $row->name;
-
-The above row() function returns an **object**. Example: $row->name
-
-Standard Query With Single Result (Array version)
-=================================================
-
-::
-
-	$query = $this->db->query('SELECT name FROM my_table LIMIT 1');
-	$row = $query->row_array();
-	echo $row['name'];
-
-The above row_array() function returns an **array**. Example:
-$row['name']
-
-Standard Insert
-===============
-
-::
-
-	$sql = "INSERT INTO mytable (title, name) VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";
-	$this->db->query($sql);
-	echo $this->db->affected_rows();
-
-Query Builder Query
-===================
-
-The :doc:`Query Builder Pattern <query_builder>` gives you a simplified
-means of retrieving data::
-
-	$query = $this->db->get('table_name');
-	
-	foreach ($query->result() as $row)
-	{
-		echo $row->title;
-	}
-
-The above get() function retrieves all the results from the supplied
-table. The :doc:`Query Builder <query_builder>` class contains a full
-compliment of functions for working with data.
-
-Query Builder Insert
-====================
-
-::
-
-	$data = array(
-		'title' => $title,
-		'name' => $name,
-		'date' => $date
-	);
-	
-	$this->db->insert('mytable', $data);  // Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')
-
