查詢結果錯誤

Question

下面的查詢在我的codeigniter項目中使用，僅給我一條記錄，但是當我在數據庫中調用此查詢並給我3條記錄時。

$query = "SELECT `teacher_subjects`.*, `subjects`.* FROM `teacher_subjects` JOIN `subjects` ON `subjects`.`id` = `teacher_subjects`.`subject_id` WHERE `teacher_subjects`.`session_id` = 11 AND `teacher_subjects`.`class_section_id` = 5"; 

$query = $this->db->query($query);

Answer 1

嘗試這個，

$query_statement = "SELECT `teacher_subjects`.*, `subjects`.* FROM `teacher_subjects` JOIN `subjects` ON `subjects`.`id` = `teacher_subjects`.`subject_id` WHERE `teacher_subjects`.`session_id` = 11 AND `teacher_subjects`.`class_section_id` = 5"; 

$query = $this->db->query($query_statement);
return ($query->num_rows() > 0) ? $query->result() : false;
