This is how you use a join in CodeIgniter:
$this->db->select('*');
$this->db->from('blogs');
$this->db->join('comments', 'comments.id = blogs.id');
$query = $this->db->get();
// Produces:
// SELECT * FROM blogs
// JOIN comments ON comments.id = blogs.id1
You can see it in the User-Guide of CodeIgniter.
http://ellislab.com/codeigniter/user-guide/database/active_record.html#select


You have to remove de second table in from command:
Example:
$this->db->select('windows_users_image_upload.*,windows_users_info.display');
$this->db->from('windows_users_info');
$this->db->join("windows_users_image_upload","windows_users_image_upload.user_id = windows_users_info.user_id");
$this->db->where("windows_users_image_upload.".$field,$value);
$query = $this->db->get();

Codeigniter Subquery

I have this query can someone help me transfer it to codeigniter style in model.
SELECT
a.*,
(
SELECT COUNT(*) FROM `comment` c
WHERE c.comment_article_id = a.`News_News_ID`
) AS counta
FROM
`news_news` a
Update:
I try this and it work nicely but im not sure it is good practice
$sql="SELECT a.*,
( SELECT COUNT(*) FROM comment c WHERE c.comment_article_id = a.`News_News_ID` ) as counta
FROM `news_news` a";
$query = $this->db->query($sql, array('News_Cate_ID' => $cate), $start, $display);

Use join instead of sub query and according to your query you didn't need where condition while using joins
$this->db->select('a.*,COUNT(c.*) AS counta');
$this->db->from('news_news AS a');
$this->db->join('comment AS c', 'c.comment_article_id = a.News_News_ID');
$query = $this->db->get();
For more information

Try below code. This query will return each article with comment count
$this->db->select('a.*,COUNT(c.*) AS count');
$this->db->from('news_news a');
$this->db->join('comment c', 'a.News_News_ID = c.comment_article_id ','LEFT');
$this->db->group_by('a.News_News_ID')
$query = $this->db->get();

How to JOIN table with converting formate date on postgresql and Codeigniter

I'am new on postgresql, i have some query like this :
SELECT * FROM "trx_mutualfund_trade" RIGHT JOIN "trx_mutualfund_nav" ON "trx_mutualfund_trade"."mtr_trade_time"::timestamp::date = trx_mutualfund_nav.mna_efective_date ....
and i try to write CI code like this :
$this->db->select('*');
$this->db->from('mutualfund_trade');
$this->db->join('mutualfund_nav', 'mutualfund_trade.mtr_trade_time::timestamp::date = mutualfund_nav.mna_efective_date', 'right');
but that CI Code produces query like this :
SELECT * FROM "trx_mutualfund_trade" RIGHT JOIN "trx_mutualfund_nav" ON "trx_mutualfund_trade"."mtr_trade_time"::"timestamp::date" = mutualfund_nav.mna_efective_date...
So that can't run because there is an doublequote on ::"timestamp::date"
Anyone can help me to show me how to write the CI code corectly?
thanks

Use this:
$query = $this->db->query("SELECT * FROM trx_mutualfund_trade RIGHT JOIN trx_mutualfund_nav ON trx_mutualfund_trade.mtr_trade_time::timestamp::date = trx_mutualfund_nav.mna_efective_date");
$result = $query->result_array();
return $result

Convert to Codeigniter Query

How to write this query in codeigniter format?
SELECT rights_management.id, rights_management.tab_name FROM rights_management
WHERE rights_management.id NOT IN (SELECT r_m.tabid FROM r_m)
Thanks for the Help . .

You can write your sub query in CI using where clause
$this->db->select('rights_management.id, rights_management.tab_name');
$this->db->from('rights_management');
$this->db->where('`rights_management.id` NOT IN (SELECT r_m.tabid FROM `r_m`)', NULL, FALSE);

First of all you have to select r_m.tabid from table r_m and store it in array.
$this->db->select('r_m.tabid');
$this->db->from('r_m');
$query = $this->db->get();
$alb = $query->result_array();
Make it to an array
foreach($alb as $rs){
$not_need[]=$rs['tabid'];
}
After that fire the general active class using where_not_in.
$this->db->where_not_in('rights_management.id', $not_need);
$this->db->select('rights_management.id, rights_management.tab_name');
$this->db->from('rights_management');
$result= $this->db->get();

$this->db->query('SELECT rights_management.id, rights_management.tab_name FROM rights_management WHERE rights_management.id NOT IN (SELECT r_m.tabid FROM r_m)');
