Create a store procedure in mysql. Using CodeIgniter 3 already configured to use the mysqli driver, I tried to get the data returned by SP but it did not succeed.
SP:
CREATE DEFINER='root'@'localhost' PROCEDURE 'SP_DadosRelatorio'(IN ano INT, IN mes INT, IN retirada INT, IN produto INT,
OUT d1 INT)
BEGIN
SELECT
ifnull(sum(qtde),0) INTO d1
FROM
saida_produto
WHERE EXTRACT(YEAR FROM data_saida) = ano
and
EXTRACT(MONTH FROM data_saida) = mes
and
EXTRACT(DAY FROM data_saida) = 1
and tipo_retirada = retirada
and id_produto = produto;
I made the call on IC 3 as follows:
$ query = $ this-> db-> query ("call SP_DataReport (2016,1,1,1, @ d1"));
When viewing the $ query-> result () I got the following message:
> > object(CI_DB_mysqli_result)[51] public 'conn_id' =>

How do I access the value of @ d1 that comes from the mysql database via store procedure?
