-<h1>Queries</h1>
-
-<h2>$this->db->query();</h2>
-
-<p>To submit a query, use the following function:</p>
-
-<code>$this->db->query('YOUR QUERY HERE');</code>
-
-<p>The <dfn>query()</dfn> function returns a database result <strong>object</strong> when "read" type queries are run,
-which you can use to <a href="results.html">show your results</a>. When "write" type queries are run it simply returns TRUE or FALSE
-depending on success or failure. When retrieving data you will typically assign the query to your own variable, like this:</p>
-
-<code><var>$query</var> = $this->db->query('YOUR QUERY HERE');</code>
-
-<h2>$this->db->simple_query();</h2>
-
-<p>This is a simplified version of the <dfn>$this->db->query()</dfn> function. It ONLY returns TRUE/FALSE on success or failure.
-It DOES NOT return a database result set, nor does it set the query timer, or compile bind data, or store your query for debugging.
-It simply lets you submit a query. Most users will rarely use this function.</p>
-
-
-<h1><br />Escaping Queries</h1>
-
-<p>It's a very good security practice to escape your data before sumbiting it into your database.
-Code Igniter has two functions that help you do this:</p>
-
-<ol>
-</li>
-<li><strong>$this->db->escape()</strong> This function determines the data type so that it
-can escape only string data. It also automatically adds single quotes around the data so you don't have to:
-
-<code>$sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")";</code>
-
-
-<li><strong>$this->db->escape_str()</strong> This function escapes the data passed to it, regardless of type.
-Most of the time you'll use the above function rather then this one. Use the function like this:
-
-<code>$sql = "INSERT INTO table (title) VALUES('".$this->db->escape_str($title)."')";</code>
-
-</li>
-</ol>
-
-
-<h1><br />Query Bindings</h1>
-
-
-<p>Bindings enable you to simplify your query syntax by letting the system put the queries together for you. Consider the following example:</p>
-
-<code>
-$sql = "SELECT * FROM some_table WHERE id = <var>?</var> AND status = <var>?</var> AND author = <var>?</var>";
-<br /><br />
-$this->db->query($sql, array(3, 'live', 'Rick'));
-</code>
-
-<p>The question marks in the query are automatically replaced with the values in the array in the second parameter of the query function.</p>
-<p class="important">The secondary benefit of using binds is that the values are automatically escaped, producing safer queries. You don't have to remember to manually escape data; the engine does it automatically for you.</p>
