我有一个像这样的数组$articles
[
(int) 0 => [
'id' => '-@940039',
'xe_dsca' => 'ÜP2768G/1',
'xe_citg' => '1F0200',
'xe_cuni' => 'stk',
'xe_seak' => 'ÜP2768G/1',
'xe_seab' => '',
'xe_wght' => '0.0153',
'xe_cwun' => 'kg',
'xe_wgap' => '2',
'xe_seri' => '2',
'xe_ltct' => '2',
'xe_qual' => '2',
'xe_hama' => '2',
'xe_ctyo' => 'DE',
'xe_ccde' => '85045095',
'xe_cpln' => '240000',
'xe_spar' => '2',
'xe_wear' => '2',
'xe_ctyo_de' => null,
'xe_cean' => null,
'xe_ewm_dsce' => null,
'xe_cood' => null,
'xe_ewm_dsne' => null,
'xe_ewm_dsge' => null,
'xe_ewm_dsen' => null,
'xe_ewm_dscz' => null,
'xe_wgh1' => null,
'xe_wgh2' => null,
'xe_wgh3' => null
],
(int) 1 => [
'id' => '000-000500-00000',
'xe_dsca' => 'DUMMY ZEITBUCHUNG',
'xe_citg' => '1F0800',
'xe_cuni' => 'stk',
'xe_seak' => 'DUMMY ZEITBUCHUN',
'xe_seab' => '000-000500-00000',
'xe_wght' => '0',
'xe_cwun' => 'kg',
'xe_wgap' => '2',
'xe_seri' => '2',
'xe_ltct' => '2',
'xe_qual' => '2',
'xe_hama' => '2',
'xe_ccde' => '000',
'xe_cpln' => '930000',
'xe_spar' => '2',
'xe_wear' => '2',
'xe_ctyo' => null,
'xe_ctyo_de' => null,
'xe_cean' => null,
'xe_ewm_dsce' => null,
'xe_cood' => null,
'xe_ewm_dsne' => null,
'xe_ewm_dsge' => null,
'xe_ewm_dsen' => null,
'xe_ewm_dscz' => null,
'xe_wgh1' => null,
'xe_wgh2' => null,
'xe_wgh3' => null
]
在我的控制器中,我有这些行
foreach ($articles AS $article) {
$query = $this->Articles->query();
$query
->insert($required_article_fields)
->values($article)
->execute();
}
此代码工作正常,但有人建议我如何在重复密钥更新时插入?什么是一次保存多行数据的最佳做法?

您可以使用查询epilog()
方法
foreach ($articles AS $article) {
$query = $this->Articles->query();
$query
->insert($required_article_fields)
->values($article)
->epilog('ON DUPLICATE KEY UPDATE field=field+1')
->execute();
}
如果需要安全地传递值,也可以将QueryExpression对象传递给该方法。

根据https://stackoverflow.com/a/26590483/80353
的建议你可以做到
$query = $this->Articles->query();
$query->insert($required_article_fields);
// need to run clause('values') AFTER insert()
$valuesExpression = $query->clause('values')->values($articles);
$query->values($valuesExpression)
->epilog('ON DUPLICATE KEY UPDATE `field1`=VALUES(`field1`) ... ')
->execute();
我没有填写您要更新的所有字段,因为我不知道哪个字段是您唯一索引的一部分。
