jone with three tables - El Forum - 09-20-2010 [eluser]shahmy[/eluser] Hi To All I have three tables in my database, 1.subject 2.grade 3.sub_to_grade. I have to create a query to retrieve subject name belongs to grade id.this subject and grade contain many to many relationship. I rote a query which i copy bellow. But it retrieve grade name belong to grade id. If any one know please help me. (Note: I am using xajax for retrieve) Thank You. Code: $this->db->select("*"); jone with three tables - El Forum - 09-21-2010 [eluser]Georgi Budinov[/eluser] Well this is because you have name field in both tables. The fastest is to change $this->db->select("*"); to $this->db->select("*, subject.name"); I am not very aware with the ActiveRecord functionality as I am not using it. You can check how to set aliases for tables and please don't use * in the select - it is always better to name all the fields you want to retrieve. jone with three tables - El Forum - 09-23-2010 [eluser]shahmy[/eluser] Hi..
