Im working on ecommerce platform. I have a query in normal form. i want to convert to codeigniter.
this is my query
SELECT products.product_name,products.product_id,products.short_description,pi.img,
CASE WHEN products.sp_price=0 THEN products.price WHEN products.sp_price!=0 THEN products.sp_price END as pprice FROM
(`offers_products`) JOIN `products` ON `offers_products`.`product_id` = `products`.`product_id`
LEFT JOIN (SELECT image_name as img,product_id as pid from product_images GROUP BY pid)pi
ON `products`.`product_id` = `pi`.`pid` .
How do i convert this to codeigniter query.
I tried, but getting syntax error. Please help me, im new to codeigniter.
There is no need to convert your query. And also the is no rule that you should use codeigniter query only.
you can use
$res = $this->db->query("your query here")->result();
$res will have that result() you want.
This will help you.
For more reference, check here
Just use
public function method_name()
{
$query = $this->db->query("SELECT products.product_name,products.product_id,products.short_description,pi.img, CASE WHEN products.sp_price=0 THEN products.price WHEN products.sp_price!=0 THEN products.sp_price END as pprice FROM (`offers_products`) JOIN `products` ON `offers_products`.`product_id` = `products`.`product_id` LEFT JOIN (SELECT image_name as img,product_id as pid from product_images GROUP BY pid)pi ON `products`.`product_id` = `pi`.`pid`");
$result = $query->result_array();
return $result;
}
We use result_array for pass data as Objective array

i am little confused in wririting SQL query for joining muthiple tables.
I have perfectly write that query in codeigniter as folows
$this->db->select('*');
$this->db->from('subscription_payment');
$this->db->join('user', 'user.user_id = subscription_payment.user_id');
$this->db->join('subscription', 'subscription.subscription_id =
subscription_payment.subscription_id');
$this->db->where('subscription_payment.subscription_payment_id',$sid);
$query = $this->db->get();
$result= $query->result_array();
Help me to convert this to SQL query
Using
echo $this->db->last_query();
will produce
select * from some_table...
And this is it. Next time you can convert any query you want with easy.
select *
from subscription_payment
join user
on user.user_id = subscription_payment.user_id
join subscription
on subscription.subscription_id = subscription_payment.subscription_id
where subscription_payment.subscription_payment_id = $sid
SELECT *
FROM subscription_payment
JOIN user ON user.user_id = subscription_payment.user_id
JOIN subscription ON subscription.subscription_id = subscription_payment.subscription_id
WHERE subscription_payment.subscription_payment_id = $sid
;
This is my query:
SELECT COUNT( DISTINCT (paypal_transaction.buyerId) ) AS cid FROM eg_posts_details
INNER JOIN paypal_transaction ON paypal_transaction.id = eg_posts_details.OrderId
WHERE seller_id =190
It runs perfectly on MySQL directly but when I run it from my PHP codeigniter model I get the #1054 error. I have no idea why this is happening. Please help.
Here is the PHP code:
$query = $this->db->query("SELECT COUNT( DISTINCT (paypal_transaction.buyerId) ) AS cid
FROM eg_posts_details
INNER JOIN paypal_transaction ON paypal_transaction.id = eg_posts_details.OrderId
WHERE seller_id =190");
As per your image reference, paypal transaction table contain buyerId and you used it as buyer_id. So use the following.
Use like this
$sql = "select count(distinct(`paypal_transaction`.`buyerId`)) as `cid` from `eg_posts_details` inner join `paypal_transaction` on `paypal_transaction`.`id` = `eg_posts_details`.`OrderId` where `seller_id`= '190' ";
$query = $this->db->query($sql);
Hope its work for you
I want to select data from my database table with join query, but my it doesn't work.
My query:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->join('schedule', 'schedule.itemtype = 'testitem'');
$this->db->where('we.isActive','Y');
This line makes problem with schedule.itemtype = 'testitem':
$this->db->join('schedule', 'schedule.itemtype = 'testitem'');
How can I solve this?
You don't need to join same table twice.
But just to extend ON clause:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid AND schedule.itemtype = \'testitem\'');
$this->db->where('we.isActive','Y');
try
$this->db->select();
$this->db->from("we");
$this->db->join("schedule", "schedule.itemid = we.cid");
$this->db->where("schedule.itemtype","testitem");
$this->db->where("we.isActive","Y");
I believe there are two problems here. The first problem is that you are using one too many quotes in the second join line in your query:
You have: $this->db->join('schedule', 'schedule.itemtype='testitem''); < extra quote
It should be: $this->db->join('schedule', 'schedule.itemtype=testitem');
Second problem: your join doesnt make sense.
Your statement:
$this->db->select();
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->join('schedule', 'schedule.itemtype = testitem');
$this->db->where('we.isActive','Y');
Translates to:
SELECT * FROM we
JOIN schedule ON schedule.itemid = we.cid
JOIN schedule ON schedule.itemtype = testitem
WHERE we.isActive = Y
As you can see you are joining the same table twice on different lines, not only that but what table does "testitem" belong to? We are left to assume that you perhaps want the join where itemtype = testitem which will mean this:
SELECT * FROM we
JOIN schedule ON schedule.itemid = we.cid
WHERE schedule.itemtype = testitem
AND we.isActive = Y
Therefore your final Codeigniter query should be:
$this->db->select('*');
$this->db->from('we');
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->where('schedule.itemtype', 'testitem');
$this->db->where('we.isActive','Y');
This will work:
$this->db->join('schedule', 'schedule.itemid = we.cid');
$this->db->where('we.isActive','Y');
$this->db->where('schedule.itemtype', 'testitem');
$this->db->get('we');
$this->db->query('select we_tbl.c_name from we we_tbl,schedule sch_tbl where sch_tbl.itemid = we_tbl.cid AND we_tbl.idActive = '.$activeData);
Try this query according to your problem this could get the data you need.
I've tested on different database but i tried to perform what you're trying to get. https://www.w3schools.com/sql/trysql.asp?filename=trysql_op_in
select
pro_tbl.ProductName,
cat_tbl.CategoryName ,
sup_tbl.SupplierName
from
Products pro_tbl,
Suppliers sup_tbl,
Categories cat_tbl
where
pro_tbl.SupplierID = sup_tbl.SupplierID AND
pro_tbl.CategoryID = cat_tbl.CategoryID;
Two possible problems, depending on what your desired outcome is:
If you need to make two joins and are getting an error with the second join clause, try using double quotes to enclose the constant value on the condition or you'll get a parse error:
$this->db->join('schedule', 'schedule.itemtype = "testitem"');
If you need to join only once with multiple conditions, use parentheses:
$this->db->select('*');
$this->db->from('we');
$this->db->join('schedule', '(schedule.itemid = we.cid AND schedule.itemtype="testitem")');
$this->db->where('we.isActive','Y');
You query is equivalent to writing:
select * from we
inner join schedule on schedule.itemid = we.cid
inner join schedule on schedule.itemtype = "testitem"
where we.isActive = 'Y'
but what you seem to need is
select * from we
inner join schedule on (schedule.itemid = we.cid AND schedule.itemtype = "testitem")
where we.isActive = 'Y'
On your original query, you are doing two joins. In the latter, you'll do only one with multiple conditions.
I have got two tables :
Dress (dress_id, title)
Dress_comment (comment_id, dress_id, comment)
I have been trying from hours now and unable to convert this query into the corresponding Codeigniters' Active Class Record functions.
Here is the query :
SELECT d.dress_id, d.title, COALESCE(dc.count, 0)
FROM dress d
JOIN (select dress_id, count(comment_id) as count from dress_comment group by dress_id) dc
ON d.dress_id = dc.dress_id
ORDER BY d.dress_id;
This is what I have tried till now :
//Creating the select subquery for the inner join
$this->db->select('dress_id, count(comment_id) as count')
->from('Dress_comment')
->group_by('dress_id')
->get();
$subQuery = $this->db->last_query();
//Main Query
$this->db->select('d.dress_id, d.title, COALESCE(dc.count,0)')
->from('Dress')
->join($subQuery . ' dc','dc.dress_id = d.dress_id','left')
->order_by('d.dress_id');
$result = $this->db->get();
return $result->result_array();
But Codeigniter is not running this query and always giving mysql syntax error. The sql format that codeigniter is converting this active methods to is
SELECT `d`.`dress_id`, `d`.`title`, COALESCE(dc.count, `0)`
FROM (`Dress`) LEFT JOIN `SELECT` `dress_id`, count(comment_id) as count
FROM (`Dress_comment`)
GROUP BY `dress_id` dc
ON `dc`.`dress_id` = `d`.`dress_id`
ORDER BY `d`.`dress_id`
I was able to solve the problem using the mysql query in the join function like this :
$this->db->select('d.dress_id, d.title, dc.count as comments, dl.count as likes, dt.title, di.image_url')
->from('Dress d')
->join('(select dress_id, count(comment_id) as count from dress_comment group by dress_id) dc','dc.dress_id = d.dress_id','left')
->order_by('d.dress_id');
I have the following code for selecting from multiple tables where the order number matches.
$orderNumber = $_GET['orderNumber'];
$sql = $db->prepare("
SELECT
*
from `KC_Orders`
INNER JOIN
`KC_Payments`
on KC_Orders.orderNumber = KC_Payments.orderNumber
INNER JOIN
`KC_OrderStatus`
on KC_Orders.orderNumber = KC_OrderStatus.orderNumber
INNER JOIN
`KC_Statuses`
on KC_OrderStatus.statusID = KC_Statuses.statusID
WHERE
orderNumber= :orderNumber");
$sql->execute(array(':orderNumber' => $orderNumber));
$orderInfo = $sql->fetchAll();
Now when I var_dump($orderInfo); it returns: array(0) { } What is wrong? All the tables include the same $orderNumber field within it. If I take the WHERE part out it works just fine except it returns every row not just one. (obviosly).
Please help us!
You need to specify what the OrderNumber is from, and the * is from (what table). So try this new code:
$sql = $db->prepare("SELECT KC_Orders.* from `KC_Orders` INNER JOIN `KC_Payments` on KC_Payments.orderNumber = KC_Orders.orderNumber INNER JOIN `KC_OrderStatus` on KC_OrderStatus.orderNumber = KC_Order.orderNumber INNER JOIN `KC_Statuses` on KC_Statuses.statusID = KC_OrderStatus.statusID WHERE KC_Orders.orderNumber= :orderNumber");
Ordernumber in where clause should have table prefix if it exists in multiple tables
Try this
$orderNumber = (int)$_GET['orderNumber'];
Then where :ordernumber is put $orderNumber
Then execute
