$con = mysql_connect(_DB_SERVER_, _DB_USER_, _DB_PASSWD_);
mysql_select_db(_DB_NAME_);

I am new to the PrestaShop. help me.

Answer 1

use

$query ="select * from name_table"; /*example query*/
Db::getInstance()->executeS($query);

you do not need anything else to make a query

Answer 2

Just include these files and thats it!

include(dirname(__FILE__).'/../../config/config.inc.php');
include(dirname(__FILE__).'/../../init.php');

And after all you can use methods as Matteo told u. Or read more here ( http://doc.prestashop.com/display/PS15/DB+class+best+practices )

Answer 3

Please, before read this guidelines to create a new module: How to create a module

And then this: Best practices of the Db Class

Including the files like the elPresta says it's old and deprecated method, after that to make a simple query, read what he wrote Matteo Enna .
