如何从codeigniter中的mysql列值中删除前导零

Question

如何从codeigniter中的MySQL列值中删除前导零值。 用于where condition.Thanks in Advance

查询语法如下， delivery_order_no可以是0001

$this->db->where("delivery_order_no","1");

Answer 1

您可以使用 intval（）功能

    $string= '0021';
$this->db->where("delivery_order_no",intval($string));

Answer 2

将delivery_order_no转换为整数，这将删除前导零。

$this->db->where("0 + delivery_order_no = $id");
