我正在尝试进行一个迁移，它会同时在不同的表上执行多个查询
$sql = ''; $sql .= "UPDATE card_series SET Code = 903 WHERE ID = 1600;"; $cardsSeries1600 = CardList::find() ->where(['seriesId' => 1600]) ->orderBy('ID'); $cardNum = 2; foreach ($cardsSeries1600->each() as $card) { if ($card->client_id != NULL) { $sql .= "DELETE FROM client_cards WHERE card_id = ".$card->ID.";"; } $number = str_pad($cardNum, 8, "0", STR_PAD_LEFT); $cardId = (1903).$number; $sql .= "UPDATE card_list SET ID = '".$cardId."', Code = 903, Number = '".$number."' WHERE ID = ".$card->ID.";"; $sql .= "UPDATE card_list_log SET card_id = '".$cardId."', Code = 903, Number = '".$number."' WHERE card_id = ".$card->ID.";"; $cardNum++; } \Yii::$app->db->createCommand($sql)->execute();
但最后，我只有一个第一个请求UPDATE card_series SET Code = 903 WHERE ID = 1600;
我尝试打印$sql变量，所有的请求都在那里，但只有第一个请求被执行
我该如何做才能让所有的请求一个接一个地执行？
你可以尝试以下方式。
public function safeUp() { $query = "你的查询语句"; $this->execute($query); }
