Datatables Where clause with two conditions

Question

I want to select records where p_code=10 & p_code=24 only for the user = 4, in my MySQL Datatables view. I used the following code fragment.

$usr = $this->session->userdata('id_user'); 
if($usr == 4)
        {
        $this->datatables->where('tbl_officer.p_code', 10);
        $this->datatables->where('tbl_officer.p_code', 24);

        } else {
        $this->datatables->where('tbl_officer.usr', $usr);
        }

But the code outs an empty result. If I remove the line, $this->datatables->where('tbl_officer.p_code', 24); the result shows only the officers with p_code=10.

How can I add these two lines with where clause in my code ? Can anyone help ?

Answer 1

Use or_where , so you can get both or one of them:

$this->datatables->where('tbl_officer.p_code', 10)->or_where('tbl_officer.p_code', 24);

And you can use where_in too:

$this->datatables->where_in('tbl_officer.p_code', [10, 24]);

Answer 2

You need to use or_where to join both statements, like so:

$this->datatables->where('tbl_officer.p_code', 10)->or_where('tbl_officer.p_code', 24);

Without it you will just run two separate queries (one for p_code == 10 and other for p_code == 24 ) and return the value of the last statement.
