問題描述

我使用 Laravel Query Builder 查詢 MySQL 數(shù)據(jù)庫，但它返回整數(shù)值作為字符串值.

I'm using Laravel Query Builder to query MySQL database but it returns integer values as string values.

我有以下查詢.

$query = DB::table('store_products')->select('products.id', 'products.name', 'products.unit_type', 'products.price', 'products.image_path', 'products.is_popular', 'store_products.price AS store_price')
           ->join('products', 'products.id', '=', 'store_products.product_id')
           ->join('product_categories', 'product_categories.product_id', '=', 'store_products.product_id')
           ->where('store_products.store_id', $store_id)
           ->where('store_products.product_id', $product_id);

此處查詢獲取存在于 Store_Products 中的 Product，用于給定 store_id.

Here the query gets Product which is existing in Store_Products for given store_id.

問題是，當(dāng)我使用查詢生成器時，它返回 id(這是產(chǎn)品的主鍵)作為 string.演員表好像有問題.

The problem is, it returns id (which is the Primary Key for Product) as string when I use Query Builder. Looks like there is something wrong with casts.

我該如何解決這個問題?

How can I solve this problem?

非常感謝您.

推薦答案

強(qiáng)制轉(zhuǎn)換不是解決方案，而是解決問題的方法.您的實際問題是缺少 mysqlnd 插件.

Casting is not a solution but a workaround to the problem. Your actual problem is missing mysqlnd plugin.

檢查mysqlnd是否像這樣安裝

$ sudo dpkg -l | grep 'mysqlnd'

如果沒有安裝，你需要像這樣安裝(假設(shè)你有php5)

If it's not installed, you need to install it like so (assuming you have php5)

$ sudo apt-get install php5-mysqlnd

這些命令適用于 ubuntu.如果您還有其他東西，只需將它們轉(zhuǎn)換為您合適的操作系統(tǒng)即可.

These commands are for ubuntu. If you have something else, just convert them to your appropriate OS.
