AI代码解释 returnResponse::json(array('success'=>true,'last_insert_id'=>$data->id),200); 上面的写法自然是对的,返回的是当前写入的条目的ID。但是,如果是并发的系统,或者在流程处理中,没有使用 Company 模型进行数据操作,而是 DB::statement,DB::insert 这些,获取到的,可就不是最后的ID了。 兼容的...
问laravel 8: insert方法get last insert id in eloquent (İnsert Method)EN表要求：有PrimaryKey，...
php//頭部引入DB類useIlluminate\Support\Facades\DB;//在方法中獲取获取上一条insert语句产生的id$id= DB::getPdo()->lastInsertId();
那么，如果想要获取存入后数据条目的ID，如何返回呢？其实，save 方法本身就是链式调用的，会返回当前的 Company 模型对象。直接调用属性值即可：$data->id;封装到 Response 响应体内：return Response::json(array('success' => true, 'last_insert_id' => $data->id), 200);上面的写法自然是对的，返回的是...

看到了吧,没有加任何容错机制,只是对insert语句返回了lastInsertId(),,然后这个还要我们自己来$db->getLastInsID()来获取,不过单纯的insert也还好啦,,想加入事务机制呢,我们接着往下看源码: publicfunctionstartTrans() {$this->initConnect(true);if ( !$this->_linkID )returnfalse;//数据rollback 支持if (...
// 统计总数$count=User::count();// 统计分组$count=User::groupBy("is_enable")->selectRaw("count(id) as aggregate")->get();// 注意不能这样写:User::select('count(id) as aggregate')->groupBy("is_enable")->get(); 1. 2.
$users = DB::table('users')->skip(10)->take(5)->get(); 二、连接 Joins 查询构建器也可以用来编写连接语句。看看下面的例子: Basic Join Statement 复制代码代码如下: DB::table('users') ->join('contacts', '', '=', 'contacts.user_id') ...
You will often need to insert new related models. For example, you may wish to insert a new comment for a post. Instead of manually setting the post_id foreign key on the model, you may insert the new comment from its parent Post model directly:1$comment = new Comment(array('message'...
