Events::on('DBQuery')

Hi 

When the system executes a query I want to parse the query and modify it. I want to create a BeforeExecuteQuery method or event. 

An example: 
The users => ID, Name, Password table 

PHP Code:

$users = new \ App\Models\UserModel(); 
$res = $ users->findAll (); 
// select ID, Name, Password from users 


I want the Password field to always be removed from query

For now it's catching the query like this, but I can't change it
Events::on('DBQuery', 'My_parser_query');
