更新数据库当前字段

Question

如何仅更新my_field？

$this->db->set('my_field', 'my_field+1', FALSE);
$this->db->where('my_other_field', 'test');
$this->db->update('my_table');

Answer 1

尝试这样，

$data['my_field'] = "value";

$this->db->where("");//where condition here
$this->db->update("tablename",$data);

或一线解决方案，

$this->db->update('tablename', $data, "where condition");

修改

$this->db->query("update my_table set my_field = my_field + 1 where my_other_field = test");
