-
-
-<h2>$this->db->last_query();</h2>
-
-<p>Returns the last query that was run (the query string, not the result).  Example:</p>
-
-<code>$str = $this->db->last_query();<br />
-<br />
-// Produces:  SELECT * FROM sometable....

-<p>The following two functions help simplify the process of writing database INSERTs and UPDATEs.</p>

-
-<h2>$this->db->insert_string(); </h2>
-<p>This function simplifies the process of writing database inserts. It returns a correctly formatted SQL insert string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$str = $this->db->insert_string('table_name', $data);
-</code>
-
-<p>The first parameter is the table name, the second is an associative array with the data to be inserted.  The above example produces:</p>
-<code>INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@your-site.com', 'www.your-site.com')</code>

-<h2>$this->db->update_string(); </h2>
-<p>This function simplifies the process of writing database updates. It returns a correctly formatted SQL update string. Example:</p>
-
-<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
-<br />
-$where = "author_id = 1 AND status = 'active'";
-<br /><br />

-
-<p>The first parameter is the table name, the second is an associative array with the data to be inserted, and the third parameter is the "where" clause. The above example produces:</p>
-<code> UPDATE exp_weblog SET name = 'Rick', email = 'rick@your-site.com', url = 'www.your-site.com' WHERE author_id = 1 AND status = 'active'</code>
