value from php into stored procedure

Question

this is my php code

<?php
$code='1,2,3';
$this->db->query("CALL SP_db(\"$code\"));
?>

if i var_dump($code) i get this string(5) "1,2,3"

and this my stored procedure code

CREATE DEFINER=`test`@`localhost` PROCEDURE `SP_db`(v_company varchar(10))

begin

select * from blabla where company_id in (v_company);
.
.
.

i use this code to insert some value into table the problem if i use this code,where i get v_company from php its not working

but if i try to fill the value it works

CREATE DEFINER=`test`@`localhost` PROCEDURE `SP_db`(v_company varchar(10))

    begin

    select * from blabla where company_id in (1,2,3);

but the value being sent by php is received by stored procedures, i try to save v_company value into table to make sure and it work

because the value from php entered into the table

so can someone tell where the code is wrong

Answer 1

When you pass '1,2,3' to your procedure, you get a string, and your query becomes

select * from blabla where company_id in ('1,2,3');

not

select * from blabla where company_id in (1,2,3);

You can use find_in_set insted of in

select * from blabla where find_in_set(company_id, v_company);

but it will not use index so well, as in does;

Answer 2

I think you are missing " .

$this->db->query("CALL SP_db(\"$code\") ");

Or try this

$this->db->query("CALL SP_db('".$code."') ");
