Question

This is mine code, I asked the end_date from the tblTest. end_date is a datetime.
Here is the code, but it give me an error:

$this->db->select(date('end_date'));
$this->db->where('topActive', 'true');
$this->db->order_by('end_date');
$this->db->group_by('end_date');
$q = $this->db->get('tblTest');

Error:

Unknown column 'UTC1107_07pm30UTC' in 'field list'
SELECT `UTC1107_07pm30UTC` 
FROM (`tblTest`) 
WHERE `topActive` = 'true' 
GROUP BY `UTC1107_07pm30UTC` 
ORDER BY `UTC1107_07pm30UTC`

What am I doing wrong?

Thanks

Answer 1

in your select method, you’re passing a date object. this method accepts the names of the columns that you need returned. end_date is your column name, so use that.

$this->db->select('end_date');

UPDATE

This is the query that ended up working:

$this->db->select("DATE(end_date) as my_end_date", FALSE);
$this->db->where('topActive', 'true');
$this->db->order_by('my_end_date');
$this->db->group_by('my_end_date');
$q = $this->db->get('tblTest');
