Question

I’m trying to join tables and getting below error in codeigniter.

Error Number: 1054

Unknown column 'links.client_id' in 'on clause'

SELECT *, `keywords`.`key_id`, `keywords`.`key_name` 
FROM (`keywords`) 
LEFT JOIN `resources` ON `resources`.`client_id` = `links`.`client_id` 
JOIN `links` ON `keywords`.`link_id` = `links`.`link_id` 
WHERE `links`.`client_id` = '181' ORDER BY `links`.`link_id` desc

I have Links table and client_id column in there. I also spelt them correctly. Below is the query in link model:

$this->db->select('*');
$this->db->from('links');
$this->db->join('resources', 'resources.client_id = links.client_id', 'LEFT');
$this->db->where('link_id', $link_id);
$query = $this->db->delete('links');
return $query;

What could be wrong?

Answer 1

I think this line is wrong:

LEFT JOIN `resources` ON `resources`.`client_id` = `links`.`client_id` 

I am guessing you want something like:

LEFT JOIN `resources` ON `resources`.`client_id` = `keywords`.`client_id` 

because you are joining resources and keywords
