如何使用Eloquent ORM在Laravel中执行批量数据库插入?

我正在处理一个XML文档,循环遍历它的元素。我想在Laravel中完成如下内容:

$sXML = download_page('http://remotepage.php&function=getItems&count=100&page=1');
$oXML = new SimpleXMLElement($sXML);
$query = "INSERT INTO tbl_item (first_name, last_name, date_added) VALUES";
foreach($oXML->results->item->item as $oEntry){
    $query .=  "('" . $oEntry->firstname . "', '" . $oEntry->lastname . "', '" . date("Y-m-d H:i:s") . "'),";
}
mysql_query($query);

但我得到以下错误。

SQLSTATE[HY093]:无效的参数号:名称参数和位置参数混合。

也许更Laravel的解决这个问题的方法是使用一个集合,并利用时间戳将它与模型循环插入。

<?php

use App\Continent;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        collect([
            ['name' => 'América'],
            ['name' => 'África'],
            ['name' => 'Europa'],
            ['name' => 'Asia'],
            ['name' => 'Oceanía'],
        ])->each(function ($item, $key) {
            Continent::forceCreate($item);
        });
    }
}

抱歉我误会了。对于批量插入,这可能会有帮助,也许有了这个,你可以做出很好的种子和优化他们一点。

<?php

use App\Continent;
use Carbon\Carbon;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $timestamp = Carbon::now();
        $password = bcrypt('secret');

        $continents = [
            [
                'name' => 'América'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'África'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Europa'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Asia'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Oceanía'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
        ];

        Continent::insert($continents);
    }
}

其他回答

我们可以很容易地更新GTF答案来更新时间戳

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);

Coder::insert($data);

更新: 简化日期,我们可以像佩德罗·莫雷拉建议的那样使用碳

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'modified_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'modified_at'=> $now
       ),
    //...
);

Coder::insert($data);

UPDATE2:对于laravel 5,使用updated_at而不是modified_at

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'updated_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'updated_at'=> $now
       ),
    //...
);

Coder::insert($data);

问题解决了…修改迁移表

$table->timestamp('created_at')->nullable()->useCurrent();

解决方案:

Schema::create('spider_news', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('source')->nullable();
    $table->string('title')->nullable();
    $table->string('description')->nullable();
    $table->string('daterss')->nullable();

    $table->timestamp('created_at')->useCurrent();
    $table->timestamp('updated_at')->useCurrent();
});

在Laravel 5.7中,你可以使用insertUsing方法。

$query = [];
foreach($oXML->results->item->item as $oEntry){
    $date = date("Y-m-d H:i:s")
    $query[] = "('{$oEntry->firstname}', '{$oEntry->lastname}', '{$date}')";
}

Builder::insertUsing(['first_name', 'last_name', 'date_added'], implode(', ', $query));

对于类别关系插入,我遇到了同样的问题,但我不知道,除了在我的雄辩模型中,我使用Self()在foreach中有一个相同类的实例来记录多个保存和抓取id。

foreach($arCategories as $v)
{                
    if($v>0){
        $obj = new Self(); // this is to have new instance of own
        $obj->page_id = $page_id;
        $obj->category_id = $v;
        $obj->save();
    }
}

如果没有“$obj = new Self()”,它只保存单个记录(当$obj为$this时)
