如何在CodeIgniter中返回所有行？

Question

I want to do a trivial SQL query with CodeIgniter, such as "SELECT * FROM mytable WHERE TRUE"

maybe one way could be this :

$this->db->get_where('mytable' , array('42' => '42'));

but "42"="42" seems unnecessary to me. How can I initialize the array so that it (CI) does not do any unnecessary computations ?

Answer 1

if you want to get all rows without any condition, then you can use

$this->db->get("mytable");

There is no need of get_where because your query SELECT * FROM mytable WHERE TRUE will always return all records.
