How to compare only the month and year between 2 tables in MySQL

Question

I try to compare 2 DATE data type between 2 tables in Model section in my codeigniter project. Below is my code in model section:

function get_absenand_evaluation_submission_data_by_submission($id){
    
    $data = array();
    if ($this->evaluation_model->get_id_emp_by_subm_id($id))
    {
        $emp_data = $this->evaluation_model->get_id_emp_by_subm_id($id);
        foreach ($emp_data as $row)
            {
                    array_push($data, $row->emp_id);
            }
    }
    
    $this->db->select('e.fname,e.lname,e.nik,e.id, jt.name AS jabatan, ar.nik, ar.nilai', 
        DATEPART (year, 'ar.tanggal') AS 'ar.tahun',
         DATEPART(month, 'ar.tanggal') AS 'ar.bulan',
         DATEPART(year, 'es.date_nilai') AS 'es.tahun',
         DATEPART(month, 'es.date_nilai') AS 'es.bulan',);
    $this->db->from('employment e');
    $this->db->join('employment_job j', 'e.id = j.emp_id', 'INNER');
    $this->db->join('job_title jt', 'j.job_title = jt.id', 'INNER');
    $this->db->join('absen_rekap ar', 'ar.tanggal, ar.nik = e.nik', 'INNER');
    $this->db->join('evaluation_submission es', 'es.date_nilai', 'INNER');
    
    $this->db->where(('ar.tahun', 'es.tahun')&&('ar.bulan', 'es.bulan'));
    $this->db->order_by('e.fname', 'asc');

    if ($data){
        $this->db->where_not_in('e.id',$data);
    }
    $query = $this->db->get();
    if ($query->num_rows() > 0)
    {
        return $query->result();
    }
    else
    {
        return FALSE;
    }
}

I try it, but I get an error. "Parse error: syntax error, unexpected 'AS' (T_AS) in C:\xampp\htdocs\erp\hrm\models\evaluation_model.php on line 259"

I know, there's an error in my query but I don't have any idea how to fix it. Please help.

Thank you! (:

Okay, I've fix my query like the following code :

$this->db->select("e.fname, e.lname, e.nik, e.id, j.emp_id, j.job_title, jt.id, jt.name AS jabatan, ar.nik,
    DATEPART (year, ar.tanggal) AS 'ar.tahun',
     DATEPART(month,ar.tanggal) AS 'ar.bulan',
     DATEPART(year, es.date_nilai) AS 'es.tahun',
     DATEPART(month, es.date_nilai) AS 'es.bulan'" );
    $this->db->from('employment e');
    $this->db->join('employment_job j', 'e.id = j.emp_id', 'INNER');
    $this->db->join('job_title jt', 'j.job_title = jt.id', 'INNER');
    $this->db->join('absen_rekap ar', 'ar.nik = e.nik', 'INNER');
    $this->db->join('evaluation_submission es', 'es.bulan = ar.bulan', 'INNER');
    $this->db->where('ar.tahun', 'es.tahun');

but still get an error

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM (employment e) INNER JOIN employment_job j ON e.id = j.emp_id I' at line 2

SELECT e.fname, e.lname, e.nik, e.id, j.emp_id, j.job_title, jt.id, jt.name AS jabatan, ar.nik, DATEPART (year, ar.tanggal) AS 'ar.tahun', DATEPART(month, ar.tanggal) AS 'ar.bulan', DATEPART(year, es.date_nilai) AS 'es.tahun', DATEPART(month, es.date_nilai) AS 'es.bulan' FROM (employment e) INNER JOIN employment_job j ON e.id = j.emp_id INNER JOIN job_title jt ON j.job_title = jt.id INNER JOIN absen_rekap ar ON ar.nik = e.nik INNER JOIN evaluation_submission es ON es.bulan = ar.bulan WHERE ar.tahun = 'es.tahun' GROUP BY ar.nik ORDER BY e.fname asc

I don't know what's wrong with my query ):

======================================================================================= [update]

I change the code like the following :

function get_absenand_evaluation_submission_data_by_submission($id){
    
    $data = array();
    if ($this->evaluation_model->get_id_emp_by_subm_id($id))
    {
        $emp_data = $this->evaluation_model->get_id_emp_by_subm_id($id);
        foreach ($emp_data as $row)
            {
                    array_push($data, $row->emp_id);
            }
    }

    $this->db->select("e.fname, e.lname, e.nik, e.id, j.emp_id, j.job_title, jt.id, jt.name AS jabatan, ar.nik,
    DATEPART (year, ar.tanggal) AS 'ar.tahun',
     DATEPART(month,ar.tanggal) AS 'ar.bulan',
     DATEPART(year, es.date_nilai) AS 'es.tahun',
     DATEPART(month, es.date_nilai) AS 'es.bulan'" );
    $this->db->from('employment e');
    $this->db->join('employment_job j', 'e.id = j.emp_id', 'INNER');
    $this->db->join('job_title jt', 'j.job_title = jt.id', 'INNER');
    $this->db->join('absen_rekap ar', 'ar.nik = e.nik', 'INNER');
    $this->db->join('evaluation_submission es', 'es.bulan = ar.bulan', 'INNER');
    $this->db->where('ar.tahun = es.tahun');
    
    $this->db->group_by('ar.nik');
    $this->db->order_by('e.fname', 'asc');
    if ($data){
        $this->db->where_not_in('e.id',$data);
    }
    var_dump($this->db);
    $query = $this->db->get();
    if ($query->num_rows() > 0)
    {
        return $query->result();
    }
    else
    {
        return FALSE;
    }
}

I've tried the var_dump($this->db); , but it appeared like this :

What is that means?

For comparison, use `year()` and `month()` functions. – sridesmet Jan 08 '15 at 10:08 — sridesmet, Jan 08 '15 at 10:08

You have a several syntax error in your code. Maybe this is not an answer, but for code formatting, I need to be use the answer box.

There is an unopened */ after

$this->db->join('job_title jt', 'j.job_title = jt.id', 'INNER');

You are closing the string here:

$this->db->select('e.fname,e.lname,e.nik,e.id, jt.name AS jabatan, ar.nik, ar.nilai',

so there will be syntax error too.

You have error in your sql, there is an unnecessary , at the end of your first query, and the quotes are wrong also:

$this->db->select("e.fname,e.lname,e.nik,e.id, jt.name AS jabatan, ar.nik, ar.nilai,
DATEPART (year, 'ar.tanggal') AS 'ar.tahun',
DATEPART(month, 'ar.tanggal') AS 'ar.bulan',
DATEPART(year, 'es.date_nilai') AS 'es.tahun'");

And you need to wrap your conditions at here:

$this->db->where("('ar.tahun', 'es.tahun') && ('ar.bulan', 'es.bulan')");

Thank you for your answer. But I still get an error after fixing my syntax. See my edited code above. — Kelimutu, Jan 09 '15 at 09:00

Try this:

$this->db->select("e.fname,e.lname,e.nik,e.id, jt.name AS jabatan, ar.nik, ar.nilai, 
        DATEPART (year, ar.tanggal) AS 'ar.tahun',
         DATEPART(month,ar.tanggal) AS 'ar.bulan',
         DATEPART(year, es.date_nilai) AS 'es.tahun',
         DATEPART(month, es.date_nilai) AS 'es.bulan'" );

You were using your quotes wrongly. For more information: What is the difference between single-quoted and double-quoted strings in PHP?

I've tried it but I still get an error :( `You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FROM (employment e) INNER JOIN employment_job j ON e.id = j.emp_id` See my edited code above. – Kelimutu Jan 09 '15 at 08:58
Try `var_dump($this->db)` just to know how your query looks like, before you execute it. – sridesmet Jan 09 '15 at 12:18
Also, try `employment_job AS j` instead of `employment_job j`, and do this for all your tables – sridesmet Jan 09 '15 at 12:24
Another thing, your where clause is wrong: change it to: `$this->db->where('ar.tahun = es.tahun');` – sridesmet Jan 09 '15 at 12:31
