how to write simple query into codeigniter query using join righ?????
$query = $this->db->query("Select staff_permissions_list.perm_type,staff_permissions_list.permission_key,staff_permissions_list.permission_label,
staff_permissions_list.id, staff_role_permissions.permission_id as p_id,staff_role_permissions.role_id
FROM staff_role_permissions
RIGHT JOIN staff_permissions_list ON staff_role_permissions.permission_id=staff_permissions_list.id
AND staff_role_permissions.role_id=$id WHERE staff_permissions_list.perm_type=0
ORDER BY staff_permissions_list.id ASC
");
if ($query->num_rows() > 0) {
return $query->result_array();
}
$this->db->select('book_id, book_name, author_name, category_name');
$this->db->from('books');
$this->db->join('category', 'category.category_id = books.category_id', 'right');
$query = $this->db->get();
you can get data using this method of right join
How about that ?
$query = $this->db
->select("Select staff_permissions_list.perm_type,staff_permissions_list.permission_key,staff_permissions_list.permission_label,staff_permissions_list.id, staff_role_permissions.permission_id as p_id,staff_role_permissions.role_id")
->from("staff_role_permissions AS srp")
->join("staff_permissions_list AS spl","srp.permission_id = spl.id","right")
->where("spl.perm_type","0")
->where("srp.role_id",$id)
->order_by("spl.id","ASC")
->get();
i put the role_id to the where section - maybe you need to put it back (not sure what you want to achieve here)

so i kinda new with codeigniter and im trying to join 3 table from my database
database 1 : dkm (id, tgl, ref, etc)
database 2 : order_product (kode_barang, packing, nama_barang, etc)
database 3 : product (kodeprod, tglpakai, etc)
im already trying what other ppl do to join more than 2 table in codeigniter but i got this error :
Error Number: 1066
Not unique table/alias: 'order_product'
SELECT *
FROM `order_product`
JOIN `order_product` ON `order_product`.`kode_barang` = `dkm`.`id`
JOIN `order_product` ON `order_product`.`kode_barang` = `produksi`.`kodeprod`
This is my code :
Bukaka_model.php
public function getOrderProduct()
{
$this->db->select('*');
$this->db->from('order_product');
$this->db->join('order_product','order_product.kode_barang = dkm.id');
$this->db->join('order_product','order_product.kode_barang = produksi.kodeprod');
$query = $this->db->get();
return $query->result();
}
You're trying to join to the same table multiple times, instead you need to join to the other tables once each.
You just need to change the names of the table you're joining to:
public function getOrderProduct()
{
$this->db->select('*');
$this->db->from('order_product');
$this->db->join('dkm','order_product.kode_barang = dkm.id');
$this->db->join('produksi','order_product.kode_barang = produksi.kodeprod');
$query = $this->db->get();
return $query->result();
}
Try this,
Here, you have a mistake in joining tables, in CI join() in the first parameter you need to pass/write table name with you want to join
public function getOrderProduct()
{
$this->db->select('*');
$this->db->from('order_product');
$this->db->join('dkm','order_product.kode_barang = dkm.id');
$this->db->join('produksi','order_product.kode_barang = produksi.kodeprod');
$query = $this->db->get();
if($query->num_rows() > 0)
{
return $query->result();
}else{
return array();
}
}
Try this:
public function getOrderProduct()
{
$this->db->select('*');
$this->db->from('order_product');
$this->db->join('dkm','dkm.id= order_product.kode_barang');
$this->db->join('produksi',' produksi.kodeprod = order_product.kode_barang');
$query = $this->db->get();
return $query->result();
}
Hello i want to join three tables but it fetch all data from user table, i just want firstname and lastname parameter in that
Here is my join query. i want something like join(user.firstname).
$this->db->select('*');
$this->db->from('post');
$this->db->join('user', 'user.id = post.cop_id');
$this->db->join('source', 'post.source_id = source.id');
$query = $this->db->get();
return $query->result();
You can do something like this:
$this->db->select('post.*, source.*, user.firstname, user.lastname');
$this->db->from('post');
$this->db->join('user', 'user.id = post.cop_id');
$this->db->join('source', 'post.source_id = source.id');
$query = $this->db->get();
return $query->result();
The table.* indicates that you want all the fields from that table.
change $this->db->select('*');
to $this->db->select('user.firstname, user.lastname');
You can define that in the select:
$this->db->select(['post.id', 'post.title', 'post.description', 'user.firstname']);

Plz help
$this->db->select('*');
$this->db->from('blogs');
$this->db->join('comments', 'comments.id = blogs.id');
http://ellislab.com/codeigniter/user-guide/database/active_record.html#select
Please go through the user guide before posting it on stackoverflow
join query is there..
try this
$this->db->join('second_table', 'second_table.id = first_table.id');
try like this
$this->db->select('*');
$this->db->from('first_table');
$this->db->join('second_table', 'second_table.col_name = first_table.col_name');
$query=$this->db->get();
if($query->num_rows()>0){
return $query->result_array();
}
for joining table you may use join() methods.
$this->db->from(table1)
$this->db->join('table2','table1.id=table2.table1_id','join options');
on condition means in which condition you want to join tables .
Join options is optional.
Join Options are: left, right, outer, inner, left outer, and right outer
What is the format in codeigniter
SELECT seq,
code,
discipline,
bacc
FROM "psced-disc" p
JOIN table2 t
ON p.code=t.psced_id
WHERE t.tableID=table2;
I already tried this and its working but without the WHERE clause
$this->db->select('seq, code, discipline,bacc');
$this->db->from('psced-disc p');
$this->db->join('table2 t', 'p.code=t.psced_id');
$query = $this->db->get();
return $query->result();
I want to add the WHERE t.tableID=table2;
Can anyone help me with this. I'm getting stuck at it.
try this code:
$this->db->select('seq, code, discipline,bacc');
$this->db->from('psced-disc p');
$this->db->join('table2 t', 'p.code=t.psced_id');
$this->db->where(array("t.tableID"=>"table2")); // or $this->db->where("t.tableID = 'table2'");
$query = $this->db->get();
return $query->result();
Can someone Tell me how to join 3 table with php?
Example
SELECT FROM table1, table2,table on INNERJOIN -------------------
let I have 3 table.(question table ,answer table and category table)
Here is example form my webpage.
Time remaining 30 minutes(I will get "30 minutes" form Category table)
1. Question (from question table)
2. answer (from answer table)
I don't know how to join 3 table.
it should be like that,
$this->db->select('*');
$this->db->from('table1');
$this->db->join('table2', 'table1.id = table2.id');
$this->db->join('table3', 'table1.id = table3.id');
$query = $this->db->get();
as per CodeIgniters active record framework
I believe that using CodeIgniters active record framework that you would just use two join statements one after the other.
eg:
$this->db->select('*');
$this->db->from('table1');
$this->db->join('table1', 'table1.id = table2.id');
$this->db->join('table1', 'table1.id = table3.id');
$query = $this->db->get();
Give that a try and see how it goes.
I created a function to get an array with the values for the fields and to join. This goes in the model:
public function GetDataWhereExtenseJoin($table,$fields,$data) {
//pega os campos passados para o select
foreach($fields as $coll => $value){
$this->db->select($value);
}
//pega a tabela
$this->db->from($table);
//pega os campos do join
foreach($data as $coll => $value){
$this->db->join($coll, $value);
}
//obtem os valores
$query = $this->db->get();
//retorna o resultado
return $query->result();
}
This goes in the controller:
$data_field = array(
'NameProduct' => 'product.IdProduct',
'IdProduct' => 'product.NameProduct',
'NameCategory' => 'category.NameCategory',
'IdCategory' => 'category.IdCategory'
);
$data_join = array
( 'product' => 'product_category.IdProduct = product.IdProduct',
'category' => 'product_category.IdCategory = category.IdCategory',
'product' => 'product_category.IdProduct = product.IdProduct'
);
$product_category = $this->mmain->GetDataWhereExtenseJoin('product_category', $data_field, $data_join);
result:
echo '<pre>';
print_r($product_category);
die;
I think in CodeIgniter the best to use ActiveRecord as wrote above.
One more thing: you can use method chaining in AR:
$this->db->select('*')->from('table1')->join('table2','table1.id=table2.id')->...
$this->db->select('*');
$this->db->from('table1');
$this->db->join('table2', 'table1.id = table2.id','JOIN Type');
$this->db->join('table3', 'table1.id = table3.id');
$query = $this->db->get();
this will give you result from table1,table2,table3 and you can use any type of join in the third variable of $this->db->join() function such as inner,left, right etc.
For executing pure SQL statements (I Don't Know About the FRAMEWORK- CodeIGNITER!!!)
you can use SUB QUERY!
The Syntax Would be as follows
SELECT t1.id
FROM example t1 INNER JOIN
(select id from (example2 t1 join example3 t2 on t1.id = t2.id)) as t2 ON t1.id = t2.id;
Hope you Get My Point!
$this->db->select('*');
$this->db->from('table1');
$this->db->join('table2', 'table1.id = table2.id', 'inner');
$this->db->join('table3', 'table1.id = table3.id', 'inner');
$this->db->where("table1", $id );
$query = $this->db->get();
Where you can specify which id should be viewed or select in specific table. You can also select which join portion either left, right, outer, inner, left outer, and right outer on the third parameter of join method.
you can modiv your coding like this
$this->db->select('a.nik,b.nama,a.inv,c.cekin,c.cekout,a.tunai,a.nontunai,a.id');
$this->db->select('DATEDIFF (c.cekout, c.cekin) as lama');
$this->db->select('(DATEDIFF (c.cekout, c.cekin)*c.total) as tagihan');
$this->db->from('bayar as a');
$this->db->join('pelanggan as b', 'a.nik = b.nik');
$this->db->join('pesankamar_h as c', 'a.inv = c.id');
$this->db->where('a.user_id',$id);
$query = $this->db->get();
return $query->result();
i hope can be resolve your SQL
function fetch_comments($ticket_id){
$this->db->select('tbl_tickets_replies.comments,
tbl_users.username,tbl_roles.role_name');
$this->db->where('tbl_tickets_replies.ticket_id',$ticket_id);
$this->db->join('tbl_users','tbl_users.id = tbl_tickets_replies.user_id');
$this->db->join('tbl_roles','tbl_roles.role_id=tbl_tickets_replies.role_id');
return $this->db->get('tbl_tickets_replies');
}
