Field Name Problem In CI3

Exquise me; it is my mistake. $this->db->query("SELECT [ID] FROM table"); not generates error message.

PHP Code:

$res=$this->db->select('[ID],[A],[B]')->FROM('DBTABLE')->GET()->RESULT(); 


is generating this field name error. This code hasn't generating error CI2. But after upgrade CI3 this model is generating error.

I think this is a query escaping problem. Because when i will change my code to

PHP Code:

$res=$this->db->select('[ID],[A],[B]',false)->FROM('DBTABLE')->GET()->RESULT(); 


it isn't generating error message again. Because escaped select function resulting SELECT "[ID]","[A]","[B]" FROM "DBTABLE"

This result is about table names too. In CI2; bracketed table names and select column hasn't problem but this occured in CI3. I think function has to remove brackets before escaping them.


In CI2

PHP Code:

$res=$this->db->select('[ID],[A],[B]',false)->FROM('[DBTABLE]')->GET()->RESULT(); 


hasn't problem but after CI3 upgrade they are problem for query now.
