raw query has schema in UPDATE

how to using raw query in UPDATE has schema like postgresql? i tried using INFORMATION_SCHEMA.TABLE in table name but still error. thanks


What error are you getting?


if i used $this->db->update('purchase.dpm',array(columns),array(value),condition) the error is Undefined table: 7 ERROR: relation "purchase.dpm" does not exist LINE 1

can the orm update the primary key value?
