Model::update() 当MySQL字段类型为bigint整型，更新条件字段值长度大于16的字符串类型，无法更新成功

CREATE TABLE test (
id int unsigned NOT NULL AUTO_INCREMENT COMMENT '表自增id',
order_no bigint NOT NULL DEFAULT '0' COMMENT '分单编号',
order_sn bigint NOT NULL DEFAULT '0' COMMENT '订单编号',
update_time int unsigned NOT NULL DEFAULT '0' COMMENT '更新时间',
create_time int unsigned NOT NULL DEFAULT '0' COMMENT '创建时间',
PRIMARY KEY (id),
UNIQUE KEY order_no (order_no),
KEY order_sn (order_sn)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='测试';

INSERT INTO test (id, order_no, order_sn, update_time, create_time) VALUES (1, 3021080720351340511, 0, 0, 0);

// $data = ['order_sn'=>'21080715996084293','order_no'=>'3021080720351340511']; //字符串类型长度大于16更新不了
$data = ['order_sn'=>'21080715996084293','order_no'=>3021080720351340511]; //整型这样可以更新
$result =  \app\model\Test::update($data,['order_no'=>$data['order_no']]);
return json($result);

Start by reproducing the provided test table and Model::update() calls, comparing the string and integer forms of the bigint order_no value. Trace the Model::update() path and its MySQL value handling; done means a string longer than 16 digits updates the matching row successfully without changing integer behavior.
