+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']
+
+Testing for Results
+===================
+
+If you run queries that might **not** produce a result, you are
+encouraged to test for a result first using the num_rows() function::
+
+	 $query = $this->db->query("YOUR QUERY");  if ($query->num_rows() > 0) {    foreach ($query->result() as $row)    {       echo $row->title;       echo $row->name;       echo $row->body;    } }
+
+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();
+
+Active Record Query
+===================
+
+The :doc:`Active Record Pattern <active_record>` 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:`Active Record <active_record>` class contains a full
+compliment of functions for working with data.
+
+Active Record 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}')
