Codeigniter | Calling Stored Procedure with IN and OUT pratameters in MYSQL - mysql

Question

This is my procedure... it's going to accept a parameter of $encoder as IN and then it will output the number of members as #current, #cancelled and #year it was encoded as OUT. I got one IN parameter ans four OUT parameters... and it works.
The problem is how am i going to do this in Codeigniter 3.
I've tried several codes refering to the codeigniter manual but i got this error..
Error Number: 1172
Result consisted of more than one row
CALL get_members_by_status(25,#current,#current,#year1)
Filename: models/Dashboardcounts.php
Line Number: 189
This is the Mysql Procedure code..
BEGIN
-- current members
SELECT
count(memstat) INTO current
FROM
members
WHERE
encoder = encoder_num
AND memstat = '1';
-- canceled members
SELECT
count(memstat) INTO cancelled
FROM
members
WHERE
encoder = encoder_num
AND memstat = '0';
-- year encoded
SELECT
date_format(memdateencode,"%Y") INTO year1
FROM
members
WHERE
encoder = encoder_num;
END
This is my Model Code...
public function linegraphchurchmemberbychurch_2(){
$query = $this->db->query('CALL get_members_by_status(25,#current,#current,#year1)');
$query1 = $this->db->query('SELECT #current');
foreach ($query1->result_array() as $row){
$data = $row;
}
return $data;
}
Any hint?
