How to print SQL statement in codeigniter model

Question

I have a sql statement in my model,

I then say

$query = $this->db->query($sql, array(fields, fields1);

if ($query) {
    return true:
} else {         


        

Answer 1

You can display the ActiveRecord generated SQL:

Before the query runs:

$this->db->_compile_select(); 

And after it has run:

$this->db->last_query();
