这是我的查询:
$this->db->select('e.emp_no', 'e.birth_date', 'e.first_name', 'e.last_name', 'e.gender', 'e.hire_date')
->from('employees AS e')
->join('titles AS t', 'e.emp_no = t.emp_no')
->join('salaries AS s', 't.emp_no = s.emp_no')
->join('dept_emp AS de', 's.emp_no = de.emp_no')
->join('departments AS d', 'de.dept_no = d.dept_no')
->join('dept_manager AS dm', 'd.dept_no = dm.dept_no')
->limit($limit, $offset)
->order_by($sort_by, $sort_order)
->group_by('e.emp_no')
->where('t.title', 'staff');
然后我用这个返回数组:
$ret['rows'] = $q->get()->result();
print_r ($ret['rows']);
输出的只是emp_no:
Array ( [0] => stdClass Object ( [emp_no] => 10002 ) [1] => stdClass Object ( [emp_no] => 10005 ) [2] => stdClass Object ( [emp_no] => 10007 ) [3] => stdClass Object ( [emp_no] => 10011 ) )
如何输出所有选定的列?
PS:我也试过用result_array()
什么都没用。
