How to select rows where column value IS NOT NULL using CodeIgniter's ActiveRecord?

Question

I\'m using CodeIgniter\'s Active Record class to query the MySQL database. I need to select the rows in a table where a field is not set to NULL:

$this->d         


        

Answer 1

CodeIgniter 3

Only:

$this->db->where('archived IS NOT NULL');

The generated query is:

WHERE archived IS NOT NULL;

$this->db->where('archived IS NOT NULL',null,false); << Not necessary

Inverse:

$this->db->where('archived');

The generated query is:

WHERE archived IS NULL;
