如何在 Codeigniter 4 中使用 WHERE CLAUSE

How to use WHERE CLAUSE in Codeigniter 4

你好,我有 2 个表学生和教员 我想把他们叫到我的索引(视图),所以我想出了如何加入他们。但是我有一个问题,我需要将这2个表分成一个类别但我不知道代码。有人可以帮我吗?

 public function getStudentReguler()
{
    return $this->db->table('student')
        ->join('faculty', 'faculty.id_faculty = student.id_student')
        ->where('category', *i want to be like, where categor = A*)
        ->get()->getResultArray();
}

谢谢

public function getStudentReguler()
{
    return $this->db->table('student')
        ->join('faculty', 'faculty.id_faculty = student.id_student')
        ->where('category', 'A')
        ->get()->getResultArray();
}

请试试这个:

$this->db->select('*')
->from('student')
->join('faculty', 'faculty.id_faculty = student.id_student')
->where('category', 'A')
->get()->getResultArray();
