this is my normal mysql command
$query = $this->db->query("SELECT `house_details`.`houses_id` , `house_details`.`house_dis` , `house_details`.`house_type` , `house_details`.`area` , `house_details`.`cost` , `house_details`.`user_id` , `image`.`thumb_path`
FROM (
`house_details`
)
LEFT JOIN `image` ON `image`.`house_id` = `house_details`.`houses_id`
AND `house_details`.`status` =1
GROUP BY `houses_id` DESC
LIMIT $start,$limit ");
return $query->result();
what is the similar code with CI active record class ??
Try this,
$this->db->select('house_details.houses_id, house_details.house_dis, house_details.house_type,house_details.area,house_details.cost,house_details.user_id,image.thumb_path');
$this->db->from('house_details');
$this->db->join('image', 'image.house_id = house_details.houses_id','left');
$this->db->where('image.status', 1);
$this->db->order_by("house_details.houses_id DESC");
$this->db->limit($limit, $start);
$query = $this->db->get();
return $query->result();
Assumed there is no group by since you wanted to order result set in descending order. If group by is there changed it to group_by and remove 'DESC'.
Try this:
$this->db->select('...')->
from('house_details')->
join('image','image.house_id=house_details.houses_id AND image.status=1','LEFT')->
where('...')->
order_by('house_details.houses_id','DESC')->
limit($start,$limit);

I written query to get record from main table tpl_upload_csv_file and get related record from tbl_process_csv. I get all the records but the problem is if i have 1 id from tpl_upload_csv_file in tbl_process_csv for 5 rows its displaying 5 times. Same record is displaying 5 times.
$this->db->select('tbl_process_csv.id, tbl_process_csv.record_no, tbl_process_csv.reason,tpl_upload_csv_file.uploaded_file_name, tpl_upload_csv_file.uploaded_date_time');
$this->db->from('tpl_upload_csv_file');
$this->db->where('tbl_process_csv.process_status', 3);
$this->db->join('tbl_process_csv', 'tbl_process_csv.csv_file_id = tpl_upload_csv_file.id', 'left');
$this->db->order_by('tbl_process_csv.date_of_processing', 'desc');
$query = $this->db->get();
print_r($query->result());die;
return $query->result();
My table structure is
tpl_upload_csv_file :
id
uploaded_file_name
uploaded_date_time
records_available
tbl_process_csv :
id
csv_file_id -->(Reference if for table tpl_upload_csv_file)
record_no
process_status
reason
Try this and let me know if any problem occur:
$this->db->select('tbl_process_csv.id, tbl_process_csv.record_no, tbl_process_csv.reason,tpl_upload_csv_file.uploaded_file_name, tpl_upload_csv_file.uploaded_date_time');
$this->db->from('tpl_upload_csv_file');
$this->db->join('tbl_process_csv', 'tbl_process_csv.csv_file_id = tpl_upload_csv_file.id', 'left');
$this->db->where('tbl_process_csv.process_status', 3);
$this->db->group_by('tbl_process_csv.csv_file_id');
$this->db->order_by('tbl_process_csv.date_of_processing', 'desc');
$query = $this->db->get();
return $query->result();
$this->db->distinct('tbl_process_csv.id');
Add this line in your code.
So, you will get distinct records w.r.t tbl_process_csv.id
I have 4 tables like this:
Now, I want to select all columns from all tables where model.featured=1. i.e.
model.id
model.name
model_attributes.id
model_attributes.attributes_value
model_images.id
model_images.model_images
attributes.id
attributes.name
attributes.value
I can only do basic level queries and I'm not sure if I'm anywhere near to the solution but this is what I have tried (returns nothing):
$this->db->select('*');
$this->db->from('model');
$this->db->join('model_images','model.id = model_images.model_id','RIGHT');
$this->db->join('model_attributes','model.id = model_attributes.model_id','RIGHT');
$this->db->join('attributes','model_attributes.attributes_id = attributes.id','RIGHT');
$this->db->where('model.featured', 1);
$query = $this->db->get();
return $query->result();
How do I achieve what I want ? Or, is there any other better methods to do it ?
// try this query
$this->db->select('*');
$this->db->from('model');
$this->db->join('model_images','model_images.model_id = model.id');
$this->db->join('model_attributes','model_attributes.model_id = model.id');
$this->db->join('attributes','attributes.id = model_attributes.attributes_id');
$this->db->where('model.featured','1');
$query = $this->db->get()->result();
return $query;
Please go through below mentioned solution.
$this->db->select('model.*,model_images.*,model_attributtes.*, attributes.*'):
Let me know if it not works for you.
Please go through below solution. If multiple table has same column name then you have to give alias for each column name which have same name in both the table. because by default CI merge all column name and generate result.
$this->db->select('*,c.name as c_name,s.name as s_name');
$this->db->from('country c');
$this->db->join('state s', 'c.id = s.country_id');
$query = $this->db->get();
While Searching I want to show the paid customers firstly, and then rest of customers list
but the problem is I want to show by random
for Example. paid customers should not mix with others.
Can anyone tell what will be query?
please help me!
I am using codeigniter
Example:
function randomval()
{
$this->db->order_by('id', 'RANDOM');
$this->db->limit(1);
$query = $this->db->get('tblname');
return $query->result_array();
}
Mysql query for your need if i understood well
SELECT `featured`,group_concat(`id` order by rand() ) as `id` FROM `dbc_posts` where `status` = 1 GROUP By `featured` ORDER BY `featured` DESC
now with php
$results = $this->db->query("SELECT `featured`,group_concat(`id` order by rand() ) as `id` FROM `dbc_posts` where `status` = 1 GROUP By `featured` ORDER BY `featured` DESC")->result_array();
$paid = $results[0];//featured = 1
// comma seprated ids of the paid people e.g :- 3,7,1,26,92 are available in
$paidusers = $results[0]["id"];
//seprate them by
$paidusers = explode(",",$paidusers);
foreach($paidusers as $paiduser)
{
$row = $this->db->get_where("dbc_posts", array("id"=> $paiduser))->row();
print_r($row );
echo "<br>";
}
// do same for unpaid
$unpaid = $results[1];//featured = 0
$unpaidusers = $results[1]["id"];
//seprate them by
$unpaidusers = explode(",",$unpaidusers);
foreach($unpaidusers as $unpaiduser)
{
$row = $this->db->get_where("dbc_posts", array("id"=> $unpaiduser))->row();
print_r($row );
echo "<br>";
}
Ask me if anything goes wrong
Set featured = 1 for paid and featured = 0 for unpaid customers in database. Then use the query
mysql_query("SELECT * FROM dbc_posts WHERE status = 1 ORDER BY featured DESC, RAND() LIMIT 1");
I have 2 tables - for orders and for documents for these orders. I want to show all orders from first table and if there are documents for these orders, to show date of documents(I take date from table documents).
I'm trying to make 2 join conditions because in table documents if I only join on idOrder, there are more than 1 row and I have to join on documents.name to be same as $this->uri->segment(3).
But I'm using the following code and it gives me error. Could I use 2 join conditions in this way:
My model is:
<?php
public function get_all_orders($user_id){
$this->db->select('ordersheader.*, customer.name as customerName,documents.date_make');
$this->db->from('ordersheader');
$this->db->join('customer', 'ordersheader.idCustomer = customer.idCustomer');
$this->db->join('documents', 'ordersheader.idOrder = documents.idOrder','left');
$this->db->join('documents as D', 'D.name="declaration"','left');
$this->db->where('ordersheader.user_id', $user_id);
$query = $this->db->get();
return $query->result_array();
}
Edited: I found solution. But it's written in pure sql, how to write it with Codeingiter syntax? My new working code is:
<?php
$query=("SELECT ordersheader.*, customer.name as customerName,documents.date_make,documents.deactivated_at
FROM ordersheader JOIN customer ON ordersheader.idCustomer = customer.idCustomer
LEFT JOIN documents
ON ordersheader.idOrder = documents.idOrder AND documents.name = '".$document."'
WHERE ordersheader.user_id = '".$user_id."' ");
$result = $this->db->query($query);
return $result->result_array();
This is wrong in your query
$this->db->join('documents as D', 'D.name="declaration"','left');
you can compare column using where clause
public function get_all_orders($user_id){
$this->db->select('ordersheader.*, customer.name as customerName,documents.date_make');
$this->db->from('ordersheader');
$this->db->join('customer', 'ordersheader.idCustomer = customer.idCustomer');
$this->db->join('documents', 'ordersheader.idOrder = documents.idOrder','left');
// $this->db->join('documents as D', 'D.name="declaration"','left'); / comment this line
$this->db->where('documents.name', 'declaration');
$this->db->where('ordersheader.user_id', $user_id);
$query = $this->db->get();
return $query->result_array();
}
I am working on codeigniter and I am writing the following query:
$this->db->select('*');
$this->db->from('tbl_profile');
$this->db->join('tbl_msg', 'tbl_msg.msg_sender_id = tbl_profile.profile_id');
$this->db->order_by("msg_id", "desc");
$query = $this->db->get('', $config['per_page'], $this->uri->segment(3));
$data['records'] = $query->result_array();
Correspondingly I am getting the following result:
SELECT (*) FROM tbl_profile
JOIN tbl_msg ON tbl_msg.msg_sender_id = tbl_profile.profile_id
Which is returninng a wrong result as I want the result corresponding to the following query:
select * from tbl_profile as A
join (select * from tbl_msg) as B on A.profile_id = B.msg_sender_id
Please help
First of all, you missing the order by clause, but I assum, you mean other differences.
If you want that, you can use this query, what will gave you back the exact code:
$this->db->select('*', FALSE);
$this->db->from('tbl_profile as A');
$this->db->join('( select * from tbl_msg ) as B', 'A.msg_sender_id = B.profile_id');
$this->db->order_by("msg_id", "desc");
$query = $this->db->get('', $config['per_page'], $this->uri->segment(3));
$data['records'] = $query->result_array();
From codeigniter user manual:
$this->db->select()
accepts an optional second parameter. If you set it to FALSE, CodeIgniter will not try to protect your field or table names with backticks. This is useful if you need a compound select statement.
