Codeigniter-Problem in Where while using group by week starting from tuesday - php

Question

I have to use yearweek() in my CodeIgniter query to group the data by week starting from Tuesday.that was working fine without a problem. then the main problem is to filter was doesn't work with Tuesday dates.that was filtered only yearweek() in where on Sunday dates.
I tried that by writing a raw query that was working fine. then I was analyzing on my query then I have found the problem. that was doesn't show equal(=) symbol between where column and values.i was put my CodeIgniter code and correct raw query then current CodeIgniter equivalent query below
function getbranchSalesreportshift($limit,$offset,$order_column,$order_type,$parameters)
{
$this->db->select("str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W') as week,b.name as branchname,g.name as groupname,st.name as shiftname,count(*) as total_sales_party,sum(s.price) as total_sales,count(case when salesAdvanceAmount > 0 then s.customerid end) as total_advance_party,sum(case when salesAdvanceAmount > 0 then salesAdvanceAmount end) as total_advance_amount,count(CASE WHEN DATE(s.creationdate) <> Date(customerCreationDate) then 1 end ) as old_sales_party,sum(CASE WHEN DATE(s.creationdate) <> Date(customerCreationDate) THEN s.price END ) as old_sales_amount,count(CASE WHEN DATE(s.creationdate) = Date(customerCreationDate) THEN 1 END ) as new_sales_party,sum(CASE WHEN DATE(s.creationdate) = Date(customerCreationDate) THEN s.price END ) as new_sales_amount,count(returnID) as return_product,sum(orn.price) as return_amount ");
if($parameters['shift']!=NULL){
$this->db->like('s.shiftID',$parameters['shift']);
}
if($parameters['cdatefrom']!=NULL){
// $this->db->where('yearweek(s.creationdate)',date('YW',strtotime($parameters['cdatefrom'])));
$this->db->where('str_to_date(concat(yearweek(s.creationdate), "tuesday"), "%X%V %W")',date('YW',strtotime($parameters['cdatefrom'])));
}
$this->db->group_by(array("s.shiftID", "str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W')"));
if(empty($order_column) || empty($order_type)){
$this->db->order_by('yearweek(s.creationdate)','asc');
}else{
$this->db->order_by($order_column,$order_type);
}
if($limit!=0){
$this->db->limit($limit,$offset);
}
$uid=$this->session->userdata('id');
$this->db->where('b.ownerid',$uid);
$this->db->join('open_returns orn','s.branchID=orn.branchID ','left');
$this->db->join('shifts st','s.shiftID=st.id ','left');
$this->db->join('group g','s.groupID=g.id ','left');
$this->db->join('branch b','s.branchID=b.id ','left');
$query = $this->db->get('super_sales s');
if($query->num_rows()>0){
return $query->result_array();
}else{
return FALSE;
}
}
this is my equivelent raw query (equal symbol cann't put between column and value near where)
SELECT str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W') as week, `b`.`name` as `branchname`, `g`.`name` as `groupname`, `st`.`name` as `shiftname`, count(*) as total_sales_party, sum(s.price) as total_sales, count(case when salesAdvanceAmount > 0 then s.customerid end) as total_advance_party, sum(case when salesAdvanceAmount > 0 then salesAdvanceAmount end) as total_advance_amount, count(CASE WHEN DATE(s.creationdate) <> Date(customerCreationDate) then 1 end ) as old_sales_party, sum(CASE WHEN DATE(s.creationdate) <> Date(customerCreationDate) THEN s.price END ) as old_sales_amount, count(CASE WHEN DATE(s.creationdate) = Date(customerCreationDate) THEN 1 END ) as new_sales_party, sum(CASE WHEN DATE(s.creationdate) = Date(customerCreationDate) THEN s.price END ) as new_sales_amount, count(returnID) as return_product, sum(orn.price) as return_amount FROM `super_sales` `s` LEFT JOIN `open_returns` `orn` ON `s`.`branchID`=`orn`.`branchID` LEFT JOIN `shifts` `st` ON `s`.`shiftID`=`st`.`id` LEFT JOIN `group` `g` ON `s`.`groupID`=`g`.`id` LEFT JOIN `branch` `b` ON `s`.`branchID`=`b`.`id` WHERE str_to_time(concat(yearweek(s.creationdate), "tuesday"), "%X%V %W") '201842' AND `b`.`ownerid` = '189' GROUP BY `s`.`shiftID`, str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W') ORDER BY `week` DESC LIMIT 50
I was found correct raw query as below but I need correct CodeIgniter coding for respective filter/where
SELECT str_to_date(concat(yearweek(creationdate), 'sunday'), '%X%V %W') as week,b.name as branchname,g.name as groupname,st.name,count(*) as total_sales_party,sum(price) as total_sales,count(case when salesAdvanceAmount > 0 then customerid end) as total_advance_party,sum(case when salesAdvanceAmount > 0 then salesAdvanceAmount end) as total_advance_amount,count(CASE WHEN DATE(creationdate) <> Date(customerCreationDate) then 1 end ) as old_sales_party,sum(CASE WHEN DATE(creationdate) <> Date(customerCreationDate) THEN price END ) as old_sales_amount,count(CASE WHEN DATE(creationdate) = Date(customerCreationDate) THEN 1 END ) as new_sales_party,sum(CASE WHEN DATE(creationdate) = Date(customerCreationDate) THEN price END ) as new_sales_amount FROM `super_sales` `s` LEFT JOIN branch b ON `s`.branchID=b.id LEFT JOIN `group` g ON `s`.groupID=g.id LEFT JOIN shifts st ON s.shiftID=st.id where str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W') = '2018-10-16' AND b.ownerid=189 GROUP BY str_to_date(concat(yearweek(s.creationdate), 'tuesday'), '%X%V %W'),s.shiftID ORDER BY week DESC
I need to filter the data by Tuesday weekdays like week column in select

Answer 1

this is a pretty tough one - because, you've to know how the query builder and the underlying DB Driver are working.
The problem is, usually the Querybuilder suffixes in case of a where condition the given key with an = per default. However in your case it doesn't because it thinks it has an operator.
This exactly happens in the following lines:
https://github.com/bcit-ci/CodeIgniter/blob/develop/system/database/DB_query_builder.php#L681
and
https://github.com/bcit-ci/CodeIgniter/blob/develop/system/database/DB_driver.php#L1485
you may found a bug here - and the best thing is to report it on the Forum.
Your solution for now is to suffix it by your own:
$this->db->where('str_to_date(concat(yearweek(s.creationdate), "tuesday"), "%X%V %W") =',date('YW',strtotime($parameters['cdatefrom'])));
