如何在 Laravel 中的 DB::Select() 中通過變量添加 SQL 查詢

Question

我有一個DB::select()查詢，我想通過變量添加動態 SQL 。

這是我想要做的，但它返回 SQL 語法錯誤。

$restaurantSql = "";
$restaurantIds = [6,43,51];

if ($someOtherVariable) {
    $restaurantSql = "AND orders.restaurant_ids IN (".implode(",", $restaurantIds).")";
}

$result = DB::select(
    "SELECT *
    FROM orders
    JOIN restaurants ON orders.restauant_id = restaurants.id
    WHERE orders.status = 'complete' :restaurant_sql AND
    orders.created_at >= :start_date",
    ["restaurant_sql" => $restaurantSql, "start_date" => $startDate]
);

start_date根據 Laravel 中的文檔工作，但restaurant_sql不起作用。 知道如何實現這一目標嗎？

我認為你的問題在這里

$result = DB::select(
    "SELECT *
    FROM orders
    JOIN restaurants ON orders.restauant_id = restaurants.id
    WHERE orders.status = 'complete'". $restaurantSql. "AND
    orders.created_at >= :start_date",
    ["restaurant_sql" => $restaurantSql, "start_date" => $startDate]
);
