Codeigniter GROUP_CONCAT

Question

I have:

$this->db->select('GROUP_CONCAT(prod_poster, poster2, poster3, poster4, poster5, poster6, poster7)');

And I have error for this and shows sql query:

SELECT GROUP_CONCAT(prod_poster, `poster2`, `poster3`, `poster4`, `poster5`, `poster6`, `poster7)`

it's problem because of ->>>> ` near poster7. this symbol must be inside bracket. whyc codeigniter do like this? and how to fix it?

Answer 1

Try doing:

$this->db->select('GROUP_CONCAT(prod_poster, poster2, poster3, poster4, poster5, poster6, poster7)', false);

If you pass false as the second argument of select() , it won't try to protect your query by adding in backticks (like it has in your example).
