Question

I try to get result from this query

$sql = "
                SET @col = NULL;
                SET @sql = NULL;

                Select
                  Group_Concat(Distinct
                    Concat(
                      'SUM(CASE WHEN tbl.sdate = ''',
                      colname,
                      ''' THEN tbl.result ELSE NULL END) AS ''',
                      colname,''''
                    )
                  ) Into @col
                From (
                    select concat(month(i.invdate),'.',year(i.invdate)) as colname
                    from invoices as i
                    where i.invtype = 1 and i.pid = 5
                    order by i.invdate  
                ) As collst;

                SET @sql = CONCAT('SELECT tbl.wrkname,', @col, ' 
                                        FROM (
                                            Select wl.wgname As wrkname, Concat(Month(i.invdate),''.'',Year(i.invdate)) as sdate, Sum(id.qty * id.price) As result
                                            From invoices As i
                                                Join invoicedetails As id
                                                    On i.pchid = id.pchid
                                                Join workgroups As w
                                                    On i.wid = w.wid
                                                Join workgrouplist As wl
                                                    On w.wglid = wl.wglid
                                            Where i.invtype = ', 1, ' And i.pid =', 5,
                                            ' Group By i.pid, sdate
                                            Order By i.invdate, wrkname
                                        ) AS tbl
                                        GROUP BY tbl.wrkname');

                PREPARE stmt FROM @sql;
                EXECUTE stmt;
                DEALLOCATE PREPARE stmt;
                "

But result was "SQLSTATE[HY000]: General error".

Problem solved: I create stored procedure and insert all query. Next i call stored procedure in php script.

$sql = "CALL GetReportByProjectBetweenDates(1, 5)";
$result = $this->db->query($sql); 

Answer 1

To run a raw sql on a controller:

$this->db->query("SELECT * FROM robots WHERE id > 0");

To run a raw sql on a model:

$this->getDi()->getShared('db')->query("SELECT * FROM robots WHERE id > 0");
