-<h1>Database Quick Start: Example Code</h1>
-
-<p>The following page contains example code showing how the database class is used. For complete details please
-read the individual pages describing each function.</p>
-
-
-<h2>Initializing the Database Class</h2>
-
-<p>The following code loads and initializes the database class based on your <a href="configuration.html">configuration</a> settings:</p>
-
-<code>$this->load->database();</code>
-
-<p>Once loaded the class is ready to be used as described below.</p>
-
-<p>Note: If all your pages require database access you can connect automatically. See the <a href="connecting.html">connecting</a> page for details.</p>
-
-
-<h2>Standard Query With Multiple Results (Object Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
- echo $row->title;<br />
- echo $row->name;<br />
- echo $row->email;<br />
-}<br />
-<br />
-echo 'Total Results: ' . $query->num_rows();
-</code>
-
-<p>The above <dfn>result()</dfn> function returns an array of <strong>objects</strong>. Example: $row->title</p>
-
-
-<h2>Standard Query With Multiple Results (Array Version)</h2>
-
-<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
-<br />
-foreach ($query->result_array() as $row)<br />
-{<br />
- echo $row['title'];<br />
- echo $row['name'];<br />
- echo $row['email'];<br />
-}</code>
-
-<p>The above <dfn>result_array()</dfn> function returns an array of standard array indexes. Example: $row['title']</p>
-
-
-<h2>Testing for Results</h2>
-
-<p>If you run queries that might <strong>not</strong> produce a result, you are encouraged to test for a result first
-using the <dfn>num_rows()</dfn> function:</p>
-
-<code>
-$query = $this->db->query("YOUR QUERY");<br />
-<br />
-if ($query->num_rows() > 0)<br />
-{<br />
- foreach ($query->result() as $row)<br />
- {<br />
- echo $row->title;<br />
- echo $row->name;<br />
- echo $row->body;<br />
- }<br />
-}
-</code>
-
-
-
-
-<h2>Standard Query With Single Result</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row();<br />
-echo $row->name;<br />
-</code>
-
-<p>The above <dfn>row()</dfn> function returns an <strong>object</strong>. Example: $row->name</p>
-
-
-<h2>Standard Query With Single Result (Array version)</h2>
-
-<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
-<br />
-$row = $query->row_array();<br />
-echo $row['name'];<br />
-</code>
-
-<p>The above <dfn>row_array()</dfn> function returns an <strong>array</strong>. Example: $row['name']</p>
-
-
-<h2>Standard Insert</h2>
-
-<code>
-$sql = "INSERT INTO mytable (title, name) <br />
- VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";<br />
-<br />
-$this->db->query($sql);<br />
-<br />
-echo $this->db->affected_rows();
-</code>
-
-
-
-
-<h2>Active Record Query</h2>
-
-<p>The <a href="active_record.html">Active Record Pattern</a> gives you a simplified means of retrieving data:</p>
-
-<code>
-$query = $this->db->get('table_name');<br />
-<br />
-foreach ($query->result() as $row)<br />
-{<br />
- echo $row->title;<br />
-}</code>
-
-<p>The above <dfn>get()</dfn> function retrieves all the results from the supplied table.
-The <a href="active_record.html">Active Record</a> class contains a full compliment of functions
-for working with data.</p>
-
-
-<h2>Active Record Insert</h2>
-
-<code>
-$data = array(<br />
- 'title' => $title,<br />
- 'name' => $name,<br />
- 'date' => $date<br />
- );<br />
-<br />
-$this->db->insert('mytable', $data);
-<br /><br />
-// Produces: INSERT INTO mytable (title, name, date) VALUES ('{$title}', '{$name}', '{$date}')</code>
