Question

出于某些奇怪的原因，我的查询中的In条件下这些参数不起作用。

如果我对参数进行硬编码，查询将返回结果：

DB::select("SELECT * FROM my_table WHERE vendor_id IN (19009, 19010)

这些不会返回结果：

DB::select("SELECT * FROM my_table WHERE vendor_id IN (':vendor_ids')", [
  ':vendor_ids' => implode([
    19010,
    19009,
  ]),
]);

DB::select("SELECT * FROM my_table WHERE vendor_id IN (':vendor_ids')", [
  ':vendor_ids' => [
    19010,
    19009,
  ],
]);

DB::select("SELECT * FROM my_table WHERE vendor_id IN (':vendor_ids')", [
  ':vendor_ids' => '19009, 19010',
]);

Answer 1

使用const obj = { "data": [{ "order_id": "336566", "customer_name": "joel", "customer_surname": "kabeya", "total_items": "0", "completed_items": "0", "percent_complete": 1, "datetime_received": "2019-01-21 15:00:27", "delivery_date": "2019-01-24", "delivery_from": "10:30", "delivery_to": "12:00", "completed": "1", "shopper": "joel" }, { "order_id": "335719", "customer_name": "joel", "customer_surname": "kabeya", "total_items": "0", "completed_items": "0", "percent_complete": 1, "datetime_received": "2018-12-24 13:46:27", "delivery_date": "2018-12-30", "delivery_from": "10:30", "delivery_to": "12:00", "completed": "1", "shopper": "joel" }, { "order_id": "336531", "customer_name": "Tay", "customer_surname": "Z", "total_items": "0", "completed_items": "0", "percent_complete": 1, "datetime_received": "2019-01-11 08:42:27", "delivery_date": "2019-01-17", "delivery_from": "10:30", "delivery_to": "12:00", "completed": "1", "shopper": "joel" }, { "order_id": "336545", "customer_name": "joel", "customer_surname": "kabeya", "total_items": "0", "completed_items": "0", "percent_complete": 1, "datetime_received": "2019-01-17 19:00:27", "delivery_date": "2019-01-18", "delivery_from": "11:00", "delivery_to": "12:00", "completed": "0", "shopper": "joel" }, { "order_id": "241918", "customer_name": "Marietjie", "customer_surname": "Short", "total_items": "44", "completed_items": "7", "percent_complete": 0.15909090909091, "datetime_received": "2018-07-25 15:18:25", "delivery_date": "2018-10-29", "delivery_from": "12:00", "delivery_to": "13:00", "completed": "0", "shopper": "Tay" }, { "order_id": "281774", "customer_name": "Ashleigh", "customer_surname": "Hodge", "total_items": "16", "completed_items": "0", "percent_complete": 0, "datetime_received": "2018-10-04 15:59:19", "delivery_date": "2018-10-29", "delivery_from": "12:00", "delivery_to": "13:00", "completed": "0", "shopper": null }, { "order_id": "336544", "customer_name": "joel", "customer_surname": "kabeya", "total_items": "0", "completed_items": "0", "percent_complete": 1, "datetime_received": "2019-01-17 08:00:27", "delivery_date": "2019-01-19", "delivery_from": "13:00", "delivery_to": "14:00", "completed": "0", "shopper": "joel" }] } //Length console.log(obj.data.length) //Child Item console.log(obj.data[3].order_id)仅返回一行。

您需要分别绑定参数，例如IN(:paramters)。因此，如果执行以下操作，您应该会得到预期的结果

IN(:parameter1, parameter2)

要动态生成参数，如果有供应商ID遍历它们，并创建另一个关联数组

DB::select("SELECT * FROM my_table WHERE vendor_id IN (':vendor_id1, :vendor_id2',...)", 
    [':vendor_id1' => 1, ':vendor_id2' => 2]);

然后

$vendors = [];
foreach ($vendorId as $id) {
    $vendors[':vendor' . $id] = $id;
}

Answer 2

Laravel有一个非常不错的query builder

尝试一下：

$resultCollection = DB::table('my_table')
    ->select('*')
    ->whereIn('vendor_id', [19009, 19010])
    ->get();

如果您确实要使用原始查询，请尝试DB::raw

像这样：

$resultCollection = DB::table('my_table')
    ->whereRaw('vendor_id IN (?)', [19010,19009])
    ->get();

无法在DB :: select的Laravel中为IN条件使用参数
