我的代碼有問題。我必須使用 id 從 5 個(gè)表中刪除數(shù)據(jù)，這些表由主鍵和外鍵連接。這是我嘗試過的，但它會(huì)顯示添加訂閱表 ID。但是已經(jīng)添加了訂閱表 id。$subscription = DB::table('tbl_asset_subscription')->where('id',$post['asset_id'])->get(); foreach($subscription as $row) { DB::table('tbl_asset_subscription')->where('id',$row->id)->delete(); } $orderId = array(); foreach($subscription as $row) { $order = DB::table('tbl_asset_order')->where('subscription_id',$row->id)->first(); $orderId[] = $order->id; } foreach($orderId as $row) { DB::table('tbl_asset_payment')->where('order_id',$row->id)->delete(); DB::table('tbl_asset_order')->where('id',$row->id)->delete(); } DB::table('tbl_asset_versions')->where('asset_id',$post['asset_id'])->delete(); DB::table('tbl_assets')->where('id',$post['asset_id'])->delete(); // DB::table('tbl_asset_subscription')->where('asset_id',$post['asset_id'])->delete(); echo(json_encode(array("result" => true)));{ "message": "SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`piccoscript`.`tbl_asset_subscription`, CONSTRAINT `fk_tbl_asset_subscription_tbl_assets` FOREIGN KEY (`asset_id`) REFERENCES `tbl_assets` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION) (SQL: delete from `tbl_assets` where `id` = 1)", "exception": "Illuminate\\Database\\QueryException", "file": "/var/www/html/piccoscript/vendor/laravel/framework/src/Illuminate/Database/Connection.php", "line": 664, "trace": [ { "file": "/var/www/html/piccoscript/vendor/laravel/framework/src/Illuminate/Database/Connection.php", "line": 624, "function": "runQueryCallback", "class": "Illuminate\\Database\\Connection", "type": "->" },

您可以暫時(shí)禁用外鍵約束
在 Laravel 中，您可以執(zhí)行以下操作：
$orderId = array();
$subscription = DB::table('tbl_asset_subscription')->where('id',$post['asset_id'])->get();
DB::transaction(function() {
DB::statement('SET FOREIGN_KEY_CHECKS=0');
foreach($subscription as $row) {
DB::table('tbl_asset_subscription')->where('id', $row->id)->delete();
}
foreach($subscription as $row) {
$order = DB::table('tbl_asset_order')->where('subscription_id', $row->id)->first();
$orderId[] = $order->id;
}
if($orderId) {
DB::table('tbl_asset_payment')->whereIn('order_id', $orderId)->delete();
DB::table('tbl_asset_order')->whereIn('id', $orderId )->delete();
}
DB::table('tbl_asset_versions')->where('asset_id', $post['asset_id'])->delete();
DB::table('tbl_assets')->where('id', $post['asset_id'])->delete();
DB::statement('SET FOREIGN_KEY_CHECKS=1');
});
echo(json_encode(array("result" => true)));

$orderId 不是關(guān)聯(lián)數(shù)組，因此出現(xiàn)錯(cuò)誤。試試這個(gè)代碼。
foreach($subscription as $row)
{
$order = DB::table('tbl_asset_order')->where('subscription_id',$row->id)->first();
$orderId[] = array(
'id' => $order->id
);
}
foreach($orderId as $row)
{
DB::table('tbl_asset_payment')->where('order_id',$row->id)->delete();
DB::table('tbl_asset_order')->where('id',$row->id)->delete();
}
DB::table('tbl_asset_versions')->where('asset_id',$post['asset_id'])->delete();
DB::table('tbl_assets')->where('id',$post['asset_id'])->delete();
// DB::table('tbl_asset_subscription')->where('asset_id',$post['asset_id'])->delete();
echo(json_encode(array("result" => true)));
